Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a dual SIM card security authentication method and device. Background Technology

[0002] In current daily use of mobile phones, security authentication is required in some scenarios.

[0003] For example, in mobile NFC payment scenarios, payment applications need to perform security authentication on the mobile phone during payment to confirm the identity of the mobile phone user and ensure payment security. Therefore, when an NFC payment application makes a payment, it initiates a security authentication request to the mobile phone's SIM (subscriber identification module) card. The mobile phone then determines the identity of the mobile phone user by reading the user's identity information on the SIM card, thereby ensuring payment security.

[0004] Current mobile phones can support dual SIM cards, and some phones also support eSIM cards in addition to dual SIM cards. However, in the current mobile phone SIM card security authentication methods, only SIM card 1 supports security authentication function. The SIM card security authentication capability of mobile phones is relatively poor, which reduces the overall security of mobile phones. Summary of the Invention

[0005] This application provides a dual SIM card security authentication method and device. By performing security authentication on SIM card 1 and SIM card 2, the method obtains the first security authentication result information corresponding to SIM card 1 and the second security authentication result information corresponding to SIM card 2, thereby realizing dual SIM card security authentication for both SIM card 1 and SIM card 2 simultaneously, improving the reliability of SIM card security authentication and enhancing the security of terminal device use.

[0006] In a first aspect, embodiments of this application provide a dual SIM card security authentication method. This method is applied to a terminal device that supports SIM card 1, SIM card 2, and eSIM card. The terminal device can enable SIM card 1 and SIM card 2, or it can enable SIM card 1 and eSIM card. The method includes: when it is determined that the dual SIM card security authentication function of the terminal device is enabled, the terminal device detects a first dual SIM card security authentication request; then, the terminal device performs security authentication on SIM card 1 according to the first dual SIM card security authentication request, obtaining first security authentication result information corresponding to SIM card 1; similarly, the terminal device performs security authentication on SIM card 2 according to the first dual SIM card security authentication request, obtaining second security authentication result information corresponding to SIM card 2; finally, the terminal device determines the dual SIM card security authentication result information based on the first and second security authentication result information.

[0007] In this possible implementation, to achieve dual SIM card security authentication, the user enables the dual SIM card security authentication function on the terminal device, allowing the terminal device to perform security authentication on both SIM cards simultaneously. Therefore, upon detecting a first dual SIM card security authentication request, the terminal device can perform security authentication on both the first and second SIM cards separately, obtaining the first security authentication result information for SIM card 1 and the second security authentication result information for SIM card 2, and then obtaining the dual SIM card security authentication result information. This achieves dual SIM card security authentication, improves the reliability of SIM card security authentication, and enhances the security of terminal device use.

[0008] In one possible implementation, the terminal uses SIM card 1 and SIM card 2. The method further includes: detecting a first SIM card switching command; detecting whether the dual SIM card security authentication function is enabled; disabling SIM card 2 and enabling eSIM card according to the first SIM card switching command; performing security authentication on SIM card 2 when the dual SIM card security authentication function is enabled to obtain third security authentication result information; and determining the dual SIM card security authentication result information based on the first security authentication result information and the third security authentication result information.

[0009] In this possible implementation, when the terminal device switches SIM cards, it can still perform security authentication on SIM card 2. Even when the terminal device disables SIM card 2 and enables the eSIM card, the security authentication of both SIM cards is not interrupted, achieving full-time security authentication for both SIM cards. Furthermore, security authentication for both SIM cards can still be performed in eSIM scenarios, enabling multi-scenario applications of this embodiment and improving the adaptability and flexibility of dual-SIM card security authentication across various scenarios.

[0010] In one possible implementation, the above-mentioned deactivation of SIM card 2 and activation of eSIM card includes: deactivating SIM card 2, maintaining a high level on the power supply pin corresponding to SIM card 2; and then activating eSIM card.

[0011] In this possible implementation, SIM card 2 is disabled but the power supply pin corresponding to SIM card 2 is still kept at a high level, ensuring that the terminal device can still perform security authentication on SIM card 2 even after SIM card 2 is disabled. Specifically, a method is provided that SIM card 2 can still be used for security authentication after it is disabled, which improves the feasibility of the embodiments of this application.

[0012] In another possible implementation, after deactivating SIM card 2 and enabling eSIM card, and before performing security authentication on SIM card 2, the method also includes: powering on the power supply pins of SIM card 2.

[0013] In this possible implementation, the power supply pin of SIM card 2 is powered on before security authentication of SIM card 2, ensuring that the terminal device can still perform security authentication of SIM card 2 even after SIM card 2 is disabled. Specifically, it provides another method to still perform security authentication of SIM card 2 after it is disabled, which improves the feasibility of the embodiments of this application.

[0014] In one possible implementation, the terminal uses SIM card 1 and eSIM card. The method further includes: detecting a second SIM card switching command; detecting whether the dual SIM card security authentication function is enabled; disabling the eSIM card and enabling SIM card 2 according to the second SIM card switching command; performing security authentication on SIM card 2 when the dual SIM card security authentication function is enabled to obtain fourth security authentication result information; and determining the dual SIM card security authentication result information based on the first security authentication result information and the fourth security authentication result information.

[0015] In this possible implementation, when the terminal device switches from eSIM card to SIM card 2, the terminal device can still perform security authentication on SIM card 2 after the switch, without interrupting the terminal device's security authentication of both SIM cards, thus achieving all-time dual SIM card security authentication. Furthermore, the ability to continue dual SIM card security authentication even in this switching scenario enables multi-scenario application of this embodiment, improving the adaptability and flexibility of dual SIM card security authentication across various scenarios.

[0016] In one possible implementation, before detecting the first dual SIM card security authentication request, the method further includes: detecting a dual SIM card security authentication function enable command; and enabling the dual SIM card security authentication function according to the dual SIM card security authentication function enable command.

[0017] In this possible implementation, the terminal can enable the dual SIM card security authentication function according to the dual SIM card security authentication function enable command; thereby realizing the selective enabling of the dual SIM card security authentication function for the terminal, improving the flexibility and implementability of the embodiments of this application. In one possible implementation, before obtaining the first dual SIM card security authentication trigger information and after obtaining the dual SIM card security authentication function enable information, the method further includes: detecting whether SIM card 1 and SIM card 2 are simultaneously present.

[0018] In this possible implementation, the terminal can detect whether SIM card 1 and SIM card 2 are both present, thereby ensuring that the terminal can enable the dual SIM card security authentication function, which improves the feasibility of the embodiments of this application.

[0019] In one possible implementation, the method further includes: determining that SIM card 1 and SIM card 2 are not simultaneously present; generating a notification that both SIM cards are not simultaneously present.

[0020] In one possible implementation, the method further includes: determining that the dual SIM card security authentication result information indicates that the dual SIM card security authentication has failed; and generating a dual SIM card security authentication failure notification.

[0022] Thirdly, embodiments of this application propose a computer-readable storage medium storing a computer program or instructions, which, when executed, implements the aforementioned mode control method.

[0042] In current daily use of mobile phones, security authentication is required in some scenarios.

[0043] For example, in mobile NFC payment scenarios, payment applications need to perform security authentication on the mobile phone during payment to confirm the identity of the mobile phone user and ensure payment security. Therefore, when an NFC payment application makes a payment, it initiates a security authentication request to the mobile phone's SIM (subscriber identification module) card. The mobile phone then determines the identity of the mobile phone user by reading the user's identity information on the SIM card, thereby ensuring payment security.

[0044] Current mobile phones support dual SIM cards, and some phones also support eSIM cards. However, in the current mobile phone SIM card security authentication methods, only SIM card 1 supports security authentication. SIM card 2 and eSIM cards can only be used as regular SIM cards and do not support security authentication. This makes it impossible to fully utilize the security features of two SIM cards, thus reducing the overall security of the mobile phone.

[0045] Based on this, embodiments of this application provide a dual SIM card security authentication method. This method is applied to a terminal that supports SIM card 1, SIM card 2, and eSIM card. The terminal can enable SIM card 1 and SIM card 2, or it can enable SIM card 1 and eSIM card. The method includes: when it is determined that the dual SIM card security authentication function of the terminal is enabled, detecting a first dual SIM card security authentication request; performing security authentication on SIM card 1 of the terminal according to the first dual SIM card security authentication request to obtain first security authentication result information corresponding to SIM card 1; performing security authentication on SIM card 2 of the terminal according to the first dual SIM card security authentication request to obtain second security authentication result information corresponding to SIM card 2; and determining dual SIM card security authentication result information based on the first and second security authentication result information.

[0046] In this embodiment, by performing security authentication on SIM card 1 and SIM card 2, the first security authentication result information corresponding to SIM card 1 and the second security authentication result information corresponding to SIM card 2 are obtained, thereby realizing dual SIM card security authentication for SIM card 1 and SIM card 2 simultaneously, improving the reliability of SIM card security authentication and enhancing the security of terminal use.

These different processing units may be independent devices or integrated into one or more processors.

[0054] The controller can generate operation control signals based on the instruction opcode and timing signals to complete the control of instruction fetching and execution.

[0055] The processor 110 may also include a memory for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. This memory can store instructions or data that the processor 110 has just used or that are used repeatedly. If the processor 110 needs to use the instruction or data again, it can retrieve it directly from the memory. This avoids repeated accesses, reduces the waiting time of the processor 110, and thus improves the efficiency of the system.

[0060] The UART interface is a universal serial data bus used for asynchronous communication. This bus can be a bidirectional communication bus. It converts the data to be transmitted between serial and parallel communication.

For example, the processor 110 communicates with the Bluetooth module in the wireless communication module 160 via the UART interface to implement Bluetooth functionality. In some embodiments, the audio module 170 can transmit audio signals to the wireless communication module 160 via the UART interface to enable music playback through Bluetooth headphones.

[0061] The MIPI interface can be used to connect the processor 110 to peripheral devices such as the display screen 194 and the camera 193. The MIPI interface includes a camera serial interface (CSI) and a display serial interface (DSI). In some embodiments, the processor 110 and the camera 193 communicate via the CSI interface to enable the shooting function of the terminal device 100. The processor 110 and the display screen 194 communicate via the DSI interface to enable the display function of the terminal device 100.

[0062] The GPIO interface can be configured via software. It can be configured as a control signal or a data signal. In some embodiments, the GPIO interface can be used to connect the processor 110 to a camera 193, a display screen 194, a wireless communication module 160, an audio module 170, a sensor module 180, etc. The GPIO interface can also be configured as an I2C interface, an I2S interface, a UART interface, a MIPI interface, etc.

It can also be used to connect headphones for audio playback. This interface can also be used to connect other terminal devices, such as AR devices.

[0064] It is understood that the interface connection relationships between the modules illustrated in the embodiments of the present invention are merely illustrative and do not constitute a structural limitation on the terminal device 100. In other embodiments of this application, the terminal device 100 may also employ different interface connection methods or combinations of multiple interface connection methods as described in the above embodiments.

[0065] The charging management module 140 receives charging input from a charger. The charger can be a wireless charger or a wired charger. In some wired charging embodiments, the charging management module 140 receives charging input from the wired charger via the USB interface 130.

In other embodiments, the power management module 141 and the charging management module 140 may be located in the same device.

[0067] The wireless communication function of the terminal device 100 can be implemented through antenna 1, antenna 2, mobile communication module 150, wireless communication module 160, modem processor and baseband processor, etc.

[0068] Antennas 1 and 2 are used to transmit and receive electromagnetic wave signals. Each antenna in terminal device 100 can be used to cover one or more communication frequency bands.

In some embodiments, at least some functional modules of the mobile communication module 150 may be housed in the processor 110. In some embodiments, at least some functional modules of the mobile communication module 150 and at least some modules of the processor 110 may be housed in the same device.

[0070] The modem processor may include a modulator and a demodulator. The modulator modulates the low-frequency baseband signal to be transmitted into a mid-to-high frequency signal. The demodulator demodulates the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to the baseband processor for processing. After processing by the baseband processor, the low-frequency baseband signal is transmitted to the application processor. The application processor outputs sound signals through an audio device (not limited to speaker 170A, receiver 170B, etc.) or displays images or videos through the display screen 194. In some embodiments, the modem processor may be a separate device. In other embodiments, the modem processor may be independent of the processor 110 and may be housed in the same device as the mobile communication module 150 or other functional modules.

[0071] The wireless communication module 160 can provide solutions for wireless communication applications on the terminal device 100, including wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), and infrared (IR) technologies. The wireless communication module 160 can be one or more devices integrating at least one communication processing module. The wireless communication module 160 receives electromagnetic waves via antenna 2, performs frequency modulation and filtering of the electromagnetic wave signals, and sends the processed signal to processor 110.

[0073] Terminal device 100 implements display functions through a GPU, display screen 194, and application processor. The GPU is a microprocessor for image processing, connected to the display screen 194 and the application processor. The GPU is used to perform mathematical and geometric calculations and for graphics rendering. Processor 110 may include one or more GPUs, which execute program instructions to generate or modify display information.

[0074] Display screen 194 is used to display images, videos, etc. Display screen 194 includes a display panel. The display panel may be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a miniature LED, a microLED, a quantum dot light-emitting diode (QLED), etc. In some embodiments, terminal device 100 may include one or N displays 194, where N is a positive integer greater than 1.

[0075] Terminal device 100 can perform shooting functions through ISP, camera 193, video codec, GPU, display 194 and application processor.

[0076] The ISP (Image Signal Processor) is used to process data fed back from the camera 193. For example, when taking a picture, the shutter is opened, and light is transmitted through the lens to the camera's photosensitive element. The light signal is converted into an electrical signal, and the camera's photosensitive element transmits the electrical signal to the ISP for processing, transforming it into an image visible to the naked eye. The ISP can also perform algorithmic optimization of image noise, brightness, and skin tone. The ISP can also optimize parameters such as exposure and color temperature of the shooting scene. In some embodiments, the ISP can be set in the camera 193.

[0077] Camera 193 is used to capture still images or videos. An object is projected onto a photosensitive element by generating an optical image through the lens. The photosensitive element can be a charge-coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the light signal into an electrical signal, which is then passed to an ISP for conversion into a digital image signal. The ISP outputs the digital image signal to a DSP for processing. The DSP converts the digital image signal into image signals in standard RGB, YUV, or other formats. In some embodiments, the terminal device 100 may include one or N cameras 193, where N is a positive integer greater than 1.

[0078] A digital signal processor (DSP) is used to process digital signals. Besides digital image signals, it can also process other digital signals. For example, when terminal device 100 selects a frequency, the DSP can perform Fourier transforms on the frequency energy.

[0079] Video codecs are used to compress or decompress digital video. Terminal device 100 may support one or more video codecs. Thus, terminal device 100 can play or record videos in various encoding formats, such as Moving Picture Experts Group (MPEG) 1, MPEG 2, MPEG 3, MPEG 4, etc.

[0080] NPU stands for Neural Network (NN) Computing Processor.

Furthermore, internal memory 121 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, universal flash storage (UFS), etc. Processor 110 executes various functional applications and data processing of terminal device 100 by running instructions stored in internal memory 121 and / or instructions stored in memory located in the processor.

[0087] Microphone 170C, also known as a "microphone" or "voice transducer," is used to convert sound signals into electrical signals. When making a phone call or sending a voice message, the user can speak by bringing their mouth close to microphone 170C, inputting the sound signal into microphone 170C. Terminal device 100 may be equipped with at least one microphone 170C. In some embodiments, terminal device 100 may be equipped with two microphones 170C, which, in addition to collecting sound signals, can also perform noise reduction. In other embodiments, terminal device 100 may be equipped with three, four, or more microphones 170C, which can collect sound signals, reduce noise, identify the sound source, and perform directional recording, etc.

[0089] Pressure sensor 170A is used to sense pressure signals and convert them into electrical signals. In some embodiments, pressure sensor 170A can be disposed on display screen 194. There are many types of pressure sensors 170A, such as resistive pressure sensors, inductive pressure sensors, and capacitive pressure sensors. A capacitive pressure sensor may include at least two parallel plates with conductive material. When force is applied to pressure sensor 170A, the capacitance between the electrodes changes. Terminal device 100 determines the pressure intensity based on the change in capacitance. When a touch operation is applied to display screen 194, terminal device 100 detects the intensity of the touch operation based on pressure sensor 170A. Terminal device 100 can also calculate the touch position based on the detection signal from pressure sensor 170A. In some embodiments, touch operations applied to the same touch position but with different touch operation intensities can correspond to different operation commands. For example: when a touch operation with an intensity less than a first pressure threshold is applied to the SMS application icon, a command to view an SMS is executed. When a touch operation with an intensity greater than or equal to the first pressure threshold is applied to the SMS application icon, a command to create a new SMS is executed.

[0090] The gyroscope sensor 170B can be used to determine the motion attitude of the terminal device 100. In some embodiments, the gyroscope sensor 170B can determine the angular velocity of the terminal device 100 about three axes (i.e., the x, y, and z axes). The gyroscope sensor 170B can be used for image stabilization. For example, when the shutter is pressed, the gyroscope sensor 170B detects the angle of the shaking of the terminal device 100, calculates the distance that the lens module needs to compensate based on the angle, and allows the lens to counteract the shaking of the terminal device 100 through reverse movement, thus achieving image stabilization. The gyroscope sensor 170B can also be used in navigation and motion-sensing game scenarios.

[0091] The barometric pressure sensor 170C is used to measure air pressure. In some embodiments, the terminal device 100 calculates altitude using the air pressure value measured by the barometric pressure sensor 170C to assist in positioning and navigation.

[0092] The magnetic sensor 170D includes a Hall sensor. The terminal device 100 can use the magnetic sensor 170D to detect the opening and closing of the flip cover. In some embodiments, when the terminal device 100 is a flip phone, the terminal device 100 can detect the opening and closing of the flip cover using the magnetic sensor 170D.

[0095] The proximity sensor 170G may include, for example, a light-emitting diode (LED) and a light detector, such as a photodiode. The LED may be an infrared LED. The terminal device 100 emits infrared light outward through the LED. The terminal device 100 uses the photodiode to detect infrared reflected light from nearby objects. When sufficient reflected light is detected, it can be determined that there is an object near the terminal device 100. When insufficient reflected light is detected, the terminal device 100 can determine that there is no object near the terminal device 100. The terminal device 100 may use the proximity sensor 170G to detect when a user holds the terminal device 100 close to their ear for a call, so as to automatically turn off the screen to save power.

[0098] Temperature sensor 170J is used to detect temperature. In some embodiments, terminal device 100 uses the temperature detected by temperature sensor 170J to execute a temperature handling strategy. For example, when the temperature reported by temperature sensor 170J exceeds a threshold, terminal device 100 reduces the performance of the processor located near temperature sensor 170J to reduce power consumption and implement thermal protection. In other embodiments, when the temperature is below another threshold, terminal device 100 heats battery 142 to prevent abnormal shutdown of terminal device 100 due to low temperature. In still other embodiments, when the temperature is below yet another threshold, terminal device 100 boosts the output voltage of battery 142 to prevent abnormal shutdown due to low temperature.

[0099] Touch sensor 170K, also known as a "touch device," can be located on display screen 194. The touch sensor 170K and display screen 194 together form a touchscreen, also known as a "touchscreen." Touch sensor 170K detects touch operations applied to or near it. The touch sensor can transmit the detected touch operation to the application processor to determine the type of touch event. Visual output related to the touch operation can be provided through display screen 194. In other embodiments, touch sensor 170K may also be located on the surface of terminal device 100, in a different position than display screen 194.

For example, different vibration feedback effects can correspond to touch operations performed on different applications (such as taking photos, playing audio, etc.). Motor 191 can also correspond to different vibration feedback effects for touch operations performed on different areas of the display screen 194. Different application scenarios (such as time reminders, receiving messages, alarm clocks, games, etc.) can also correspond to different vibration feedback effects. The touch vibration feedback effect can also be customized.

[0103] Indicator 192 can be an indicator light, used to indicate charging status, power changes, or to indicate messages, missed calls, notifications, etc.

[0104] The SIM card interface 195 is used to connect a SIM card. The SIM card can be inserted into or removed from the SIM card interface 195 to make contact with and separate from the terminal device 100. The terminal device 100 can support one or N SIM card interfaces, where N is a positive integer greater than 1. The SIM card interface 195 can support Nano SIM cards, Micro SIM cards, SIM cards, etc. Multiple cards can be inserted into the same SIM card interface 195 simultaneously. The multiple cards can be of the same or different types. The SIM card interface 195 is also compatible with different types of SIM cards. The SIM card interface 195 is also compatible with external memory cards. The terminal device 100 interacts with the network through the SIM card to realize functions such as calls and data communication. In some embodiments, the terminal device 100 uses an eSIM, i.e., an embedded SIM card. The eSIM card can be embedded in the terminal device 100 and cannot be separated from the terminal device 100.

[0105] Figure 2A , 2B The diagram below illustrates the architecture of multiple SIM cards in the terminal device provided in the embodiments of this application (2C). Figure 2A , 2B As shown in Figure 2C, the terminal device in this embodiment can support SIM card 1 and SIM card 2. In one possible implementation, the terminal device also supports an eSIM card. Specifically, as shown... Figure 2A As shown, SIM card slot 1 is the SIM card interface for SIM1. The VCC1 pin of slot 1 supplies power to SIM1, and the VPP1 pin is a reserved communication pin. The system-on-a-chip (SOC) of the terminal device interacts with SIM1 via the Single-Wire Protocol (SWP) to read the user identity information corresponding to SIM1. Similarly, SIM card slot 2 is the SIM card interface for SIM2. The VCC2 pin of slot 2 supplies power to SIM2, and the VPP2 pin is a reserved communication pin. The SOC of the terminal device interacts with SIM2 via the SWP to read the user identity information corresponding to SIM2. This terminal device uses a contactless front-end (CLF). The (end) chip module includes an eSIM card, which can directly interact with the terminal device's SOC. Furthermore, when the eSIM card is enabled, the terminal device can independently control the power supply to SIM card 1 and SIM card 2. Therefore, whether SIM card 1 and SIM card 2 are enabled, or SIM card 1 and eSIM card are enabled, the terminal device has the hardware capability to perform security authentication on SIM card 1 and SIM card 2.

[0106] In the embodiments of this application, such as Figure 2A As shown, the eSIM card can be built into the CLF module; in addition, the eSIM card can also be used as... Figure 2B As shown, it can be directly connected to the SOC; or it can be connected as follows: Figure 2C As shown, since it is built into the SOC, the location of the eSIM card is not limited in this embodiment of the application.

[0107] In this embodiment, the terminal device can perform security authentication on SIM card 1 and SIM card 2 using a single-wire protocol (SWP) to obtain the corresponding SIM card security authentication result information. Single-wire connection is a specification for a single-wire connection between the SIM card and the near-field communication (NFC) chip of the cellular phone. SWP is an interface between the contactless front-end (CLF) and the SIM card chip. It is a protocol used for contactless communication. For example, in existing single-wire protocols, pin C6 of the SIM card chip is connected to the CLF for SWP support. It is a bit-oriented full-duplex protocol, meaning it can transmit and receive simultaneously. When communicating between the SIM card and the SOC, the terminal's CLF or PMU can provide power to the SIM card, transmitting clock, data, and signals for bus management. The transmitted data is represented by the binary states of voltage and current on the single wire.

[0108] The software system of terminal device 100 can adopt a layered architecture, event-driven architecture, microkernel architecture, microservice architecture, or cloud architecture. This embodiment of the invention uses the layered architecture Android system as an example to exemplify the software structure of terminal device 100.

[0109] The following is combined with Figures 3 to 5 The technical solutions of this application will be described in detail with specific method embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0110] For example, Figure 3 A flowchart illustrating a dual-SIM card security authentication method provided in an embodiment of this application. (Refer to...) Figure 3 As shown, the dual SIM card security authentication method may specifically include the following steps:

[0111] 301. The terminal device detected a command to enable the dual SIM card security authentication function.

[0112] The terminal device detects a command to enable the dual SIM card security authentication function. This command instructs the terminal device to enable the dual SIM card security authentication function.

[0113] In this embodiment, the terminal device may support SIM card 1 and SIM card 2, or it may support SIM card 1, SIM card 2 and eSIM card. When the terminal device supports SIM card 1, SIM card 2 and eSIM card, the terminal device may enable SIM card 1 and SIM card 2, or it may enable SIM card 1 and eSIM card. The specifics are not limited here.

[0114] In this embodiment of the application, the terminal device has the function of simultaneously performing security authentication on dual SIM cards. That is, when SIM card authentication is required, the terminal device can perform security authentication on both SIM card 1 and SIM card 2, and use the security authentication results of SIM card 1 and SIM card 2 as the results of SIM card security authentication.

[0115] For example, a terminal device can receive a dual SIM card security authentication function activation command from a user. This command instructs the terminal device to activate the dual SIM card security authentication function. After receiving this command, the terminal device can detect the corresponding instruction, which is the dual SIM card security authentication function activation command. The terminal device can then activate the dual SIM card security authentication function according to this command.

[0116] 302. The terminal device determines whether both SIM cards are in place.

[0117] After detecting the dual SIM card security authentication function activation command, the terminal device can determine whether SIM card 1 and SIM card 2 are both in place, thereby confirming whether dual SIM card security authentication can be achieved.

[0118] In one possible implementation, the terminal device can generate a notification that the dual SIM cards are not simultaneously present when it determines that both SIM cards are not simultaneously present. This notification is used to inform the user that the terminal device does not have both SIM cards simultaneously present.

[0119] In one possible implementation, the terminal device may generate a dual SIM card simultaneous presence notification upon determining that both SIM cards are simultaneously present, to inform the user that both SIM cards are now in use. Alternatively, in this implementation, the terminal device may not generate a dual SIM card simultaneous presence notification; this is not limited here.

[0120] 303. Enable dual SIM card security authentication function on terminal devices.

[0121] When a dual SIM card security authentication function activation command is detected, and both SIM card 1 and SIM card 2 are in place, the terminal device enables the dual SIM card security authentication function.

[0122] In this embodiment of the application, after the terminal device enables the dual SIM card security authentication function, when SIM card security authentication is required, the terminal device can perform security authentication on both SIM card 1 and SIM card 2, and use the security authentication results of SIM card 1 and SIM card 2 as the results of SIM card security authentication.

[0123] In one possible implementation, the terminal device can enable the dual SIM card security authentication function if it does not detect the command to enable the dual SIM card security authentication function, but the specific implementation is not limited here.

[0124] 304. The terminal device detected the first dual SIM card security authentication request.

[0125] When the dual SIM card security authentication function of the terminal device is enabled, the terminal device can detect the first dual SIM card security authentication request, and the terminal device can perform security authentication on SIM card 1 and SIM card 2 through the first dual SIM card security authentication request.

[0126] It is understood that, in this embodiment of the application, when the dual SIM card security authentication function of the terminal device is enabled, the terminal device can activate the dual SIM card security authentication function to perform security authentication on SIM card 1 and SIM card 2 after detecting the SIM card security authentication request. Therefore, it can be understood that the SIM card security authentication request is a dual SIM card security authentication request.

[0127] For example, when a mobile phone makes an NFC payment, the NFC payment application installed on the phone needs to verify the user's identity, which can be done through SIM card security authentication. Therefore, the NFC payment application can generate a corresponding SIM card security authentication request. Since the terminal device in this embodiment supports dual SIM card security authentication, this SIM card security authentication request can be a dual SIM card security authentication request. It can be understood that this dual SIM card security authentication trigger information is used to trigger the terminal device to perform security authentication for SIM card 1 and SIM card 2.

[0128] In one possible implementation, the first dual-SIM security authentication request may simply request SIM card security authentication without specifying whether the authentication is for a single SIM card or two SIM cards; that is, it does not request dual-SIM card security authentication. Since the dual-SIM security authentication function of the terminal device is already enabled, the terminal device can request dual-SIM card security authentication based on the first SIM card security authentication request.

[0129] In another possible implementation, the first dual SIM card security authentication request can also be for the security authentication of SIM card 1 and SIM card 2, that is, the first dual SIM card security authentication request is limited to dual card security authentication.

[0130] In one possible implementation, the terminal device may detect only a single SIM card security authentication request. For example, the terminal device may detect a single SIM card security authentication request only for SIM card 1. When the dual SIM card security authentication function of the terminal device is enabled, the terminal device can also perform security authentication on SIM card 1 based on the single SIM card security authentication request and obtain the corresponding SIM card 1 security authentication result information.

[0131] 305. The terminal device performs security authentication on SIM card 1 and SIM card 2, and obtains the corresponding SIM card security authentication result information.

[0132] The terminal device performs security authentication on SIM card 1 according to the first dual SIM card security authentication request and obtains the first security authentication result information; the terminal device performs security authentication on SIM card 2 according to the first dual SIM card security authentication request and obtains the second security authentication result information.

[0133] In one possible implementation, the terminal device supports SIM card 1, SIM card 2, and eSIM card. The terminal enables SIM card 1 and SIM card 2. The terminal device can perform security authentication on SIM card 1 according to a first dual-SIM card security authentication request, obtaining a first security authentication result. The terminal device can also perform security authentication on SIM card 2 according to the same request, obtaining a second security authentication result. In this possible implementation, such as... Figure 2A , 2B As shown in Figure 2C, the terminal device performs security authentication on the SIM card by reading the user identity information in the SIM card through the reserved VPP pin.

[0134] In another possible implementation, the terminal device supports SIM card 1, SIM card 2 and eSIM card. The terminal enables SIM card 1 and eSIM card. The terminal device can perform security authentication on SIM card 1 according to the first dual SIM card security authentication request and obtain the first security authentication result information. The terminal device can also perform security authentication on SIM card 2 according to the first dual SIM card security authentication request and obtain the second security authentication result information.

[0135] Among the possible implementations, such as Figure 2A , 2BAs shown in Figure 2C, for the already activated SIM card 1, the user identity information in the SIM card is read through the reserved VPP pin in the conventional manner. For SIM card 2, although the terminal device has not activated SIM card 2, when performing security authentication on SIM card 2, the user identity information in the SIM card 2 can be read through the reserved VPP pin of SIM card 2 while the power supply pin (VCC pin) of SIM card 2 is powered on.

[0136] 306. The terminal device confirms the security authentication result information of the dual SIM cards.

[0137] The terminal device determines the dual SIM card security authentication result information based on the first security authentication result information corresponding to SIM card 1 and the second security authentication result information corresponding to SIM card 2.

[0138] Specifically, if both the first security authentication result information and the second security authentication result information indicate that the security authentication has been successfully passed, the terminal device can determine that the dual SIM card security authentication result is that the dual SIM card security authentication has been successfully passed; if at least one of the first security authentication result information and the second security authentication result information indicates that the security authentication has failed, the terminal device can determine that the dual SIM card security authentication result is that the dual SIM card security authentication has failed.

[0139] In one possible implementation, when the dual SIM card security authentication result is that the dual SIM cards have failed the security authentication, the terminal device can generate a dual SIM card security authentication failure notification. This dual SIM card security authentication failure notification is used to notify the user that the dual SIM card security authentication result has failed.

[0140] One possible implementation is, such as Figure 4 As shown, the terminal device supports SIM card 1, SIM card 2, and eSIM card. The terminal enables SIM card 1 and SIM card 2. Figure 3 The method shown also includes:

[0141] 401. The terminal device detected a first SIM card switching command.

[0142] The terminal device detects a first SIM card switching command, which instructs the terminal device to disable SIM card 2 and enable the eSIM card.

[0143] 402. Check whether the dual SIM card security authentication function is enabled on the terminal device.

[0144] After detecting the first SIM card switching command, the terminal device checks whether the dual SIM card security authentication function is enabled. Understandably, after switching SIM cards, the terminal device needs to determine whether the user still needs to enable the dual SIM card security authentication function; therefore, after detecting the SIM card switching command, the terminal device needs to check whether the dual SIM card security authentication function is enabled.

[0145] If the terminal device confirms that the dual SIM card security authentication function is enabled, then proceed with the subsequent steps as shown in Figures 403-404; if the terminal device confirms that the dual SIM card security authentication function is disabled, then the terminal device only performs step 403 to disable SIM card 2 and enable eSIM card, and does not perform steps 404 and 405.

[0146] 403. The terminal device, according to the first SIM card switching instruction, disables SIM card 2 and enables the eSIM card;

[0147] According to the first SIM card switching instruction, the terminal device disables SIM card 2 and enables eSIM card.

[0148] In one possible implementation, to achieve dual SIM card security authentication, the terminal device will not power the SIM card 2 pins when SIM card 2 is disabled. Figure 2A , 2B Instead of powering down the VCC pin in SIM 2C, the terminal device continuously supplies power to this power supply pin so that it can perform security authentication of SIM card 2.

[0149] In another possible implementation, the terminal device can power down the power supply pin of the SIM card when SIM card 2 is disabled, and power up the power supply pin again when the SIM card security authentication needs to be recorded later. The specific implementation is not limited here.

[0150] 404. When the dual SIM card security authentication function is enabled, the terminal device performs security authentication on SIM card 2 and obtains the third security authentication result information.

[0151] When the terminal device confirms that the dual SIM card security authentication function is enabled, it performs security authentication on SIM card 2 and obtains the third security authentication result information.

[0152] In one possible implementation, when the terminal device disables SIM card 2, it does not power the SIM card 2's power supply pins. Figure 2A , 2B Instead of powering down the VCC pin in SIM 2C, the terminal device continuously supplies power to this pin to enable security authentication of SIM card 2. Therefore, the terminal device can perform security authentication of SIM card 2 in the same way as when SIM card 2 is not deactivated.

[0153] In another possible implementation, when the terminal device disables SIM card 2, it can power down the power supply pin of SIM card 2. When subsequent security authentication of SIM card 2 is required, the power supply pin is then powered up again. Therefore, when the terminal device performs security authentication on SIM card 2, it needs to first power down the power supply pin of SIM card 2. Figure 2A , 2B The system powers on the VCC pin of SIM card 2 and then obtains the user identity information corresponding to SIM card 2 through the VPP pin of SIM card 2 for security authentication.

[0154] 405. The terminal device determines the dual SIM card security authentication result information based on the first security authentication result information and the third security authentication result information.

[0155] The terminal device determines the dual SIM card security authentication result information based on the first security authentication result information and the third security authentication result information.

[0156] In this embodiment of the application, it can be understood that the first security authentication result information has already been obtained in step 304, therefore in Figure 4 The method shown does not require re-authenticating the SIM card 1 to obtain the first security authentication result information.

[0157] In this embodiment, step 405, which determines the dual SIM card security authentication result information based on the first security authentication result information and the third security authentication result information, is similar to step 306 and will not be described again here.

[0158] Another possible implementation, such as Figure 5 As shown, the terminal device supports SIM card 1, SIM card 2, and eSIM card. The terminal enables SIM card 1 and eSIM card. Figure 3 The method shown also includes:

[0159] 501. The terminal device detected a second SIM card switching command.

[0160] The terminal device detects a second SIM card switching command, which instructs the terminal device to disable the eSIM card and enable SIM card 2.

[0161] 502. Check whether the dual SIM card security authentication function is enabled on the terminal device.

[0162] Upon detecting a second SIM card switching command, the terminal device can check whether the dual SIM card security authentication function is enabled. Understandably, after switching SIM cards, the terminal device needs to determine whether the user still needs to enable the dual SIM card security authentication function; therefore, upon detecting a SIM card switching command, the terminal device needs to check whether the dual SIM card security authentication function is enabled.

[0163] If the terminal device confirms that the dual SIM card security authentication function is enabled, then the subsequent steps shown in Figures 503-505 will be executed; if the terminal device determines that the dual SIM card security authentication function is disabled, then the terminal device will only execute step 503 to disable the eSIM card and enable the SIM card 2, and will not execute steps 504 and 505.

[0164] 503. The terminal device disables the eSIM card and enables the SIM card 2 according to the second SIM card switching instruction.

[0165] According to the second SIM card switching instruction, the terminal device disables the eSIM card and enables the SIM card 2.

[0166] 504. When the dual SIM card security authentication function is enabled, the terminal device performs security authentication on the SIM card 2 and obtains the fourth security authentication result information.

[0167] When the terminal device confirms that the dual SIM card security authentication function is enabled, it performs security authentication on SIM card 2 and obtains the fourth security authentication result information.

[0168] 505. The terminal device determines the dual SIM card security authentication result information based on the first security authentication result information and the fourth security authentication result information.

[0169] The terminal device determines the dual SIM card security authentication result information based on the first security authentication result information and the fourth security authentication result information.
