[0031] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.
[0032] An electronic certificate is a terminal device with specific functions, such as one or more of identity authentication (such as student card, employee card), access control, and bus card. It is equipped with a SIM card, in which a specific application is written to achieve specific functions.
[0033] However, it is difficult to flexibly add new electronic cards according to the existing scenarios, and it is difficult to update the electronic card data. The electronic certificate can only realize its factory functions and is difficult to expand.
[0034] Research has found that the electronic card of the existing electronic certificate is written into the SIM card of the electronic certificate. Adding or updating the electronic card depends on the SIM card in the electronic certificate, which requires the authorization of the operator, resulting in limited scenarios for expanding the functions of the electronic certificate.
[0035] Based on this, in an embodiment of the present application, an electronic certificate is provided, including a certificate body, a controller, a communication module, and a SIM card and SE chip that are independent of each other in structure; the SE chip, SIM card and controller are all independently arranged inside the certificate body; the SE chip is connected to the controller, and the controller is connected to the SIM card; the controller is used to connect to a business platform through the SIM card and the communication module to interact with the business platform for data; the controller is also used to interact with the SE chip for data, send the acquired data to the SE chip, install a new electronic card in the SE chip, update the original electronic card and its business data, thereby expanding the air card issuance capability for the electronic certificate based on the SE chip and the controller and realizing online downloading, updating of SE applications and other operations, using the SE chip to achieve function expansion, and adding additional functions without operator management.
[0036] Please refer to Figure 1 , Figure 1 The circuit diagram of the electronic certificate described in the embodiment of the present application is shown; Figure 1As shown, it includes a certificate body, a controller 101, a communication module, and a SIM card and an SE chip 102 that are independent of each other in structure; the SE chip 102, the SIM card and the controller 101 are independently arranged inside the certificate body;
[0037] The SE chip 102 is connected to the controller 101, and the controller 101 is connected to the SIM card 100;
[0038] The controller 101 is used to connect to the service platform through the SIM card 100 and the communication module to exchange data with the service platform;
[0039] The controller 101 is also used to perform data exchange with the SE chip 102 .
[0040] The SIM card 100 and the SE chip 102 are independent of each other in structure, that is, the SIM card 100 and the SE chip 102 are separated.
[0041] In some embodiments, the electronic certificate and the SE chip are equipped with an electronic wallet; and / or;
[0042] The certificate body is provided with a card slot for accommodating the SIM card; and / or;
[0043] The SE chip and the controller are fixed on a circuit board included in the electronic certificate.
[0044] Specifically, a card slot for a SIM card 100 is provided in the certificate body, and the SIM card can be removed and installed.
[0045] The SE chip 102 and the controller 101 are fixed on a circuit board.
[0046] In some embodiments, the communication module is integrated into the controller 101, that is, the chip used by the controller 101 is integrated with a communication module, such as a smart 4G module.
[0047] In some embodiments, the communication module may be independent of the controller 101 .
[0048] That is to say, in some embodiments, in the electronic certificate, the controller 101 is integrated with the communication module or is independent of the communication module.
[0049] In the embodiment of the present application, the communication module is exemplarily a cellular network module, that is, a 2g / 3g / 4g / 5g module. The communication module accesses the Internet based on the SIM card 100.
[0050] Cellular networks (especially 4G and 5G networks) have extensive coverage around the world, which ensures that electronic certificates can maintain good communication connections regardless of whether they are in cities, suburbs or some remote areas. Moreover, electronic certificates mainly realize functions such as campus cards, senior citizen cards, and bus cards. It is difficult to ensure stable WiFi network coverage in these scenarios. Therefore, cellular networks are used to achieve network connection.
[0051] Moreover, the 2G / 3G / 4G / 5G network modules are generally compatible with the mobile communication networks in the electronic cards, which means that the electronic card in the electronic certificate can be easily integrated into the existing communication system of the electronic certificate without complicated network configuration or modification.
[0052] The controller 101 is used to interact with the business platform and obtain data to realize data interaction between the electronic card and the business platform. The obtained data can be electronic card data or business data of the electronic card.
[0053] The controller 101 is used to connect to the service platform through the SIM card 100 and the communication module, and to perform data interaction with the service platform. Specifically, the controller 101 obtains the first electronic card data of at least one electronic card from the service platform, and transmits the first electronic card data of the at least one electronic card to the SE chip 102, so that the SE chip 102 processes the first electronic card data, constructs a new electronic card, and obtains the initial service data in the electronic card.
[0054] In the embodiment of the present application, the controller 101 is further configured to obtain electronic card update data from the service platform, and send the electronic card update data to the SE chip 102 to update the electronic card in the SE chip 102 .
[0055] The electronic card data is the data required to activate the electronic card, such as the application code, or the electronic card installation package, which is a collection of all files, data and codes required for the electronic card application, used to build the electronic card.
[0056] The electronic card update data is used to update the version of the electronic card in the SE chip 102, repair the failure of the electronic card, etc.
[0057] The business data refers to the business information related to the electronic card. This business information is necessary for the normal operation of the electronic card function and reflects the usage and status of the card, such as the recharge balance, identity information, validity period, etc.
[0058] The business platform is a business platform corresponding to the electronic card, such as a transportation company business platform corresponding to a bus card, a campus card business platform corresponding to a campus card, and an elderly card management platform corresponding to an elderly card.
[0059] The business platform may be a server, a cloud, etc.
[0060] The controller 101 may also be referred to as MCU.
[0061] The electronic card is provided with a SIM card 100, and the electronic card in the electronic certificate is pre-installed in the SIM card 100 when leaving the factory.
[0062] The electronic certificate in the embodiment of the present application has a new SE chip 102 in addition to the independent SIM card 100. When a new electronic card needs to be expanded, the application of the electronic card is independent of the SIM card 100 and is installed in the SE chip 102, thereby realizing functional expansion of the electronic certificate such as application download and update based on the independent SE chip 102 without the need for operator authorization.
[0063] At the same time, the use of an independent SE chip 102 can increase the flexibility of the electronic certificate. Since the SE chip 102 is an independent hardware component, it can be upgraded, replaced or reconfigured as needed to adapt to different application scenarios and requirements.
[0064] The SE chip 102 is a hardware security module that provides a private space isolated from the host operating system (Host OS) for storing, processing and protecting sensitive data, such as payment credentials, digital certificates, etc. The following is a detailed description of this process, which can ensure the integrity and security of the data and prevent it from being tampered with or stolen by malware or attackers. The SE of the electronic certificate complies with the financial industry standards and has a higher security level.
[0065] Based on this, an electronic wallet is installed in the SE chip 102 in the embodiment of the present application, thereby making the payment service of the electronic certificate more secure.
[0066] In the electronic certificate described in the embodiment of the present application, the controller 101 serves as a host, and the SE chip 102 serves as a slave.
[0067] In the electronic certificate described in the embodiment of the present application, the SE chip 102 is connected to the controller 101. Specifically, the controller 101 includes a host data interface, and the SE chip 102 includes a slave data interface; the host data interface of the controller 101 and the slave data interface of the SE chip 102 are connected through a data line to perform data exchange through the data line.
[0068] Specifically, the host data interface of the controller 101 is an SPI interface, and the slave data interface of the SE chip 102 is an SPI interface; the controller 101 and the SE chip 102 are communicatively connected via an SPI data line to perform data exchange via the SPI data line.
[0069] Furthermore, the ISR interface of the controller 101 is connected to the IO interface of the SE chip 102 via a signal line, and the controller 101 receives a target signal output by the IO interface of the SE chip 102 via the ISR interface.
[0070] The SPI data line is a high-speed, full-duplex synchronous serial communication bus. The SPI interface 1021 supports high-speed data transmission and is suitable for scenarios where fast data exchange is required in electronic certificates. The IO interface supports basic data read and write operations, transmission enable status and other signals.
[0071] The SE chip 102 acts as a slave, generates an interrupt signal, and sends the interrupt signal to the controller 101 through a signal line connected to the controller 101; the controller 101 acts as a host, and processes the interrupt signal.
[0072] Exemplarily, the NFC module 1022 generates an interrupt signal when the communication with the external NFC device is completed. For example, the SE chip 102 sends an interrupt signal through the IO port after the card is swiped. After receiving the interrupt signal, the controller 101 wakes up from the sleep state.
[0073] When the SE chip 102 sends an interrupt signal through the IO port after a card swiping event occurs, the controller 101 wakes up from the sleep state after receiving the signal. The controller 101 can respond to the signal quickly and wake up from the sleep state almost without delay, achieving real-time response, ensuring the efficiency of the electronic certificate system and the smoothness of the user experience; in most cases, the controller 101 is in a sleep state to save energy, and the controller 101 will only be awakened when the interrupt signal is triggered, thereby avoiding unnecessary energy consumption. This on-demand wake-up method helps to extend the battery 104 life of the device.
[0074] Therefore, in the embodiment of the present application, the SE chip 102 and the controller 101 are connected via two data lines, an SPI data line and an IO signal line, each having its own division of labor, thereby improving the efficiency and reliability of the interaction between the SE chip 102 and the controller 101 and saving energy.
[0075] In addition to being difficult to expand into electronic cards, electronic certificates based on traditional technology also lack NFC payment capabilities and can only be paid using WeChat / Alipay QR codes, which is not convenient to use. In particular, the screenless version of the electronic certificate cannot have payment functions, making it difficult to pay with special cards such as senior citizen cards and student cards.
[0076] Based on this, the electronic certificate described in the embodiment of the present application further includes an NFC module and a coil antenna 103; the SE chip 102 is connected to the coil antenna 103 via the NFC module;
[0077] The SE chip 102 communicates with an external NFC device through the NFC module and the coil antenna 103;
[0078] The controller 101 is connected to the SE chip 102 .
[0079] That is to say, in the embodiment of the present application, the electronic certificate has a connection relationship between the controller 101-SE module and the coil antenna 103.
[0080] In some embodiments, the NFC module 1022 is integrated into the SE chip 102. In other words, the SE chip 102 is integrated with the NFC module 1022.
[0081] Specifically, the SE chip 102 in the embodiment of the present application extends two metal probes, which are connected to the coil antenna 103 through the metal probes, so that the coil antenna 103 is located outside the electronic certificate.
[0082] Placing the coil antenna 103 outside can make it closer to an external NFC (near field communication) device, thereby enhancing the communication effect and transmission speed. NFC technology communicates based on magnetic field induction, so the closer the physical distance between the antennas, the better the communication effect.
[0083] So, please refer to Figure 2 The SE chip 102 described in the embodiment of the present application integrates an NFC module 1022 and an SPI interface 1021.
[0084] In the electronic certificate described in the embodiment of the present application, a tuning capacitor is further provided between the coil antenna 103 and the SE chip 102 .
[0085] In electronic certificates, the addition of tuning capacitors can ensure the stability and reliability of NFC communication. Since electronic certificates are usually used in various environments, such as different temperatures, humidity, and electromagnetic interference, stable and reliable NFC communication is essential for the normal operation of electronic certificates. Tuning capacitors can help electronic certificates maintain stable communication performance in various environments.
[0086] The SE chip 102 communicates with an external NFC device through the coil antenna 103 to realize various functions such as card payment and access control, thereby providing users with great convenience and security functions.
[0087] In the electronic certificate described in the embodiment of the present application, the NFC module and the coil antenna 103 constitute a receiver, which is used to exchange data with an external NFC reader / writer, receive target data transmitted by the external NFC reader / writer, and transmit the received target data to the SE chip 102.
[0088] Exemplarily, the SE chip 102, based on the NFC module and the coil antenna 103, receives the second electronic card data of the electronic card transmitted by the external NFC reader / writer. Specifically, the SE chip 102, based on the NFC module 1022, receives the second electronic card data sent by the corresponding NFC transmitter.
[0089] That is, the second electronic card data is written into the SE through the NFC channel using the smart card standard format.
[0090] Based on this, in the information processing method of the electronic certificate described in the embodiment of the present application, when using the SE chip 102 for function expansion, the new electronic card can be loaded based on the communication between the controller 101 and the business platform, or the new electronic card can be loaded based on the NFC module 1022.
[0091] In the embodiment of the present application, the SE chip 102 can also obtain the electronic card update data based on the NFC module 1022; specifically, the SE chip 102 receives the electronic card update data sent by the corresponding NFC sending end based on the NFC module 1022.
[0092] In this way, the electronic card described in the embodiment of the present application is based on the NFC module 1022 and has NFC function, and realizes functions such as card payment, access control, adding new electronic cards, and updating new electronic cards based on the NFC function; especially for electronic certificates without screens, the payment function is particularly important.
[0093] In some embodiments, the electronic certificate further includes a Bluetooth module, wherein the controller 101 and the SE chip 102 perform data exchange based on the Bluetooth module, and the Bluetooth module serves as the master control of the SE chip 102; or, the Bluetooth module and the SE chip 102 perform data exchange through the controller 101, and the controller 101 serves as the master control of the SE chip 102;
[0094] and / or,
[0095] The SE chip 102 also exchanges data with external devices through the Bluetooth module.
[0096] In other words, contactless payment can be realized based on the Bluetooth module.
[0097] The electronic certificate may use a Bluetooth module instead of an NFC module to realize contactless payment, or it may have both the functions of contactless payment based on a Bluetooth module and contactless payment based on an NFC module.
[0098] When implementing contactless payment based on Bluetooth, the Bluetooth module can be used as the main control of the SE module, and the 4g chip can be used as the communication module. At this time, the SE module and the 4g chip interact through the Bluetooth module.
[0099] Alternatively, a 4G chip is used as the main control of the SE module, and the 4G chip serves as a transit channel between the Bluetooth and SE modules.
[0100] Please refer to Figure 1 The electronic certificate described in the embodiment of the present application also includes a power module and a switch 106, the power module is connected to the controller 101; the power module is connected to the SE chip 102 through the switch 106, and the control input end of the switch 106 is connected to the signal output end of the switch 106 of the controller 101.
[0101] In the embodiment of the present application, the SE chip 102 (Secure Element) is a core component in the electronic certificate that stores sensitive information (such as payment credentials, access control keys, etc.), and its security is of vital importance. By controlling the power supply of the SE chip 102 by the controller 101, it can be ensured that the SE chip 102 is powered off when it is not needed, so that the SE chip 102 is in a closed state when it is not authorized or not needed, thereby effectively preventing illegal access or data leakage and improving data security; the controller 101 can control the power supply of the SE chip 102 according to the usage of the electronic certificate to avoid continuous power consumption of the SE chip 102 when idle. When the SE chip 102 needs to be used, the controller 101 can respond quickly and power it to ensure that the SE chip 102 can immediately enter the working state.
[0102] In the embodiment of the present application, specifically, the switch 106 module includes a battery 104 and a voltage conversion circuit 105, the output end of the battery 104 is connected to the voltage conversion circuit 105, the output end of the voltage conversion circuit 105 is connected to the controller 101 and the SE chip 102, and the voltage conversion circuit 105 can stably convert the voltage of the battery 104 into a chip voltage, for example, stably convert it into 1.8V.
[0103] Preferably, in the electronic certificate described in the embodiment of the present application, the voltage conversion circuit 105 adopts a low voltage difference linear regulator.
[0104] Low Dropout Regulator, or LDO (Low Dropout Regulator); The working principle of LDO is to control the conduction degree of an adjustment tube (usually a transistor) based on the voltage difference between the input voltage and the output voltage to achieve the purpose of stabilizing the output voltage.
[0105] LDO has the characteristic of low voltage difference, that is, when the difference between the input voltage and the output voltage is very small, it can still stably output the voltage required by the SE chip 102 and the controller 101, ensuring the stable operation of the SE chip 102 and the controller 101.
[0106] Those skilled in the art can clearly understand that in the several embodiments provided in the present application, it should be understood that the disclosed components can be implemented in other ways. The device embodiments described above are only schematic. For example, the division of the modules is only a logical function division. There may be other division methods in actual implementation. For example, multiple modules or components can be combined or integrated into another system, or some features can be ignored or not executed. Another point is that the mutual coupling or direct coupling or communication connection shown or discussed can be through some communication interfaces, and the indirect coupling or communication connection of devices or modules can be electrical, mechanical or other forms.
[0107] The modules described as separate components may or may not be physically separated, and the components shown as modules may or may not be physical units, that is, they may be located in one place or distributed on multiple network units. Some or all of the units may be selected according to actual needs to achieve the purpose of the solution of this embodiment.
[0108] In addition, each functional unit in each embodiment of the present application may be integrated into one processing unit, or each unit may exist physically separately, or two or more units may be integrated into one unit.
[0109] In some embodiments, the independent SIM card 100, the independent SE chip 102, and the controller 103 are located on the same circuit board.
[0110] In some embodiments, the independent SIM card 100, the independent SE chip 102, and the controller 103 on the same circuit board are located in the same plane to facilitate wiring harness arrangement.
[0111] In some embodiments, the certificate body includes a display screen, buttons, etc., and electronic certificate devices such as electronic student certificates and pension certificates can perform functions such as making and receiving calls and sending text messages.
[0112] It should be noted that in traditional technology, hardware version upgrades usually include steps such as redesigning hardware circuits and wiring, replacing hardware components, and adjusting the adaptation method to solve the compatibility between old and new hardware versions. Therefore, in traditional technology, the hardware version upgrade cycle of electronic certificates is long and the cost is high. Although the electronic certificate described in the embodiment of the present application also upgrades the electronic certificate, there is no need to change the original hardware architecture of the electronic certificate. Only the SPI interface is expanded to connect the SE chip, and the material cost only increases the SE chip and the NFC antenna."; "SPI is a universal bus protocol, and general MCUs have this interface. At the same time, the electronic certificate main control also has this interface. The SE chip can be connected to the SPI bus to achieve communication between the two chips. This process will not affect the software design and functions of the original electronic certificate.
[0113] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
