Description

Encryption method selection, device, terminal equipment, and computer-readable storage medium

[0001] This application claims priority to Chinese Patent Application No. 202510041905.1, filed on January 8, 2025, entitled "Encryption Method Selection Method, Apparatus, Terminal Equipment and Computer-Readable Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, specifically to an encryption method selection method, apparatus, terminal device, and computer-readable storage medium. Background Technology

[0003] Wireless network connectivity (Wi-Fi connectivity) has become a widely used and relied-upon wireless connectivity technology in daily life. Many devices and applications support the use of Wi-Fi connectivity and rely on Wi-Fi connectivity to further realize their functions and technologies.

[0004] In existing technologies, the main encryption methods used in Wi-Fi connections include OPEN, WEP, WPA, WPA2, and WPA3, with OPEN, WPA2, and WPA3 being the most widely used. Furthermore, existing network devices, such as routers, are increasingly supporting multiple hybrid encryption methods, such as WPA / WPA2, WPA2 / WPA3, and WEP / WPA / WPA2. Therefore, when a network device's encryption mode is configured to support multiple encryption methods simultaneously, the terminal device can also choose different encryption methods for communication connections, provided its system supports them.

Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of the aforementioned features.

The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0075] First, let's explain the terms used in this application:

[0076] WPA2 (Wi-Fi Protected Access II) is a wireless network security protocol introduced by the Wi-Fi Alliance to improve the security of wireless networks. WPA2 is an improvement over the earlier WPA (Wi-Fi Protected Access), primarily employing stronger encryption mechanisms and authentication methods. WPA2 is widely supported, from home routers to enterprise-level network equipment and various Wi-Fi terminal devices (such as laptops, smartphones, and tablets).

[0077] WPA3 (Wi-Fi Protected Access III) is a next-generation wireless network security protocol introduced by the Wi-Fi Alliance. It aims to replace and improve upon WPA2 to address increasingly complex security threats and enhance user network security. WPA3 introduces a series of new features and improvements to provide greater security and ease of use. In some mixed environments, some devices may not support WPA3. In such cases, a WPA2 / WPA3 hybrid mode can be used to ensure compatibility, but it's crucial to ensure a successful transition to a pure WPA3 environment.

[0078] AP: Access Point, short for Wireless Access Point. A wireless access point is a device in a wireless local area network (WLAN) that allows wireless devices (such as laptops, smartphones, tablets, etc.) to connect to a wired network. It acts as a bridge, connecting wireless devices to a wired network that is connected to the internet or a local area network (LAN). Network devices include, but are not limited to, routers, smartphones, etc., in AP mode for any specific Wi-Fi network.

[0079] STA: Station, typically used to refer to client devices in a wireless network, i.e., terminal devices, also known as Wi-Fi terminal devices. STA devices include, but are not limited to, any smartphones, tablets, laptops, etc., that have Wi-Fi STA mode.

[0080] BSSID: Basic Service Set Identifier, is a key concept in wireless networks. It is used to uniquely identify a wireless access point (AP) or a basic service set (BSS) within a wireless network. BSSID is typically the MAC address (Media Access Control address) of the wireless access point, used to distinguish different wireless networks and access points, especially in environments with multiple wireless network coverage.

[0081] This application provides an encryption method selection method, apparatus, terminal device, and computer-readable storage medium. Specifically, this application provides an encryption method selection apparatus applicable to the encryption method selection method. The encryption method selection apparatus includes a processing module for a terminal device, which can be a laptop, smartphone, tablet, or other device capable of connecting to a wired network via a wireless access point.

[0082] In the current technology, with the popularization and version upgrades of WPA3, both terminal devices and network devices have shown different preferences for WPA2 and WPA3. WPA2 and WPA3 each have their advantages and disadvantages. Because WPA2 has been used for a long time and has undergone many years of use and iteration, most network devices now support WPA2, and its connection process is relatively stable. Its disadvantage is relatively poor security, as it can be cracked by intercepting related information. WPA3, on the other hand, is a newer encryption method. Some network devices on the market do not yet support WPA3, and the compatibility of some network devices with WPA3 is not perfect. Its connection stability is relatively worse than WPA2, but WPA3 has better security; its complex encryption algorithm is not easy to crack.

[0083] Stability and security are characteristics of WPA2 and WPA3, respectively, and the degree of emphasis on these two features varies in different usage environments. For WPA2 / WPA3 hybrid encryption, terminal devices can choose to use either WPA2 or WPA3 encryption.

[0084] For example, as the Android operating system continues to upgrade, support for WPA3 has been gradually added in different versions of Android. When a terminal device supports WPA3, it will prioritize the use of WPA3 encryption. Therefore, under the WPA2 / WPA3 hybrid encryption method, there is a logic for choosing between WPA2 and WPA3. In an Android device, when attempting to connect to a Wi-Fi network and updating an old configuration, WPA3 is prioritized. If the configuration information of the network device (AP, Access Point) to be connected to before connection uses the KeyMgmt (Key Management) encryption algorithm PSK (Pre-Shared Key) and the terminal device's own system supports WPA3 upgrade functionality, then the encryption algorithm will be upgraded from PSK to SAE (Simultaneous Authentication of Equals), that is, WPA2 will be upgraded to WPA3. In practical applications, the terminal device triggers a scan of the surrounding environment's access points (APs) to obtain and search for the SSID (Service Set Identifier) ​​of the AP to be connected to. If there is an AP that supports WPA3 in the set of APs with the same name, and there is no AP that only supports WPA2, then WPA2 can be upgraded to use WPA3.

[0085] For example, in Apple's iOS system, when a phone is used as a hotspot (in this case, the terminal device is an access point (AP) device, not a standalone (STA) device), there is a maximum compatibility setting in its settings interface. When maximum compatibility is enabled, the hotspot is configured to use the 2.4GHz band with WPA2 encryption; when maximum compatibility is disabled, the hotspot is configured to use the 5GHz band with WPA2 / WPA3 hybrid encryption. It is evident that in the current environment, Apple's system can change the encryption method for hotspots according to user needs.

[0086] However, existing encryption upgrade methods only include the upgrade logic for WPA2 to WPA3. Furthermore, Apple's maximum compatibility settings do not apply to network connections on STA devices.

[0087] Therefore, existing encryption method selection or upgrade methods have technical problems such as the terminal device being unable to select the preferred encryption method according to the user's settings preferences, and the terminal device being unable to automatically switch encryption methods when one of the encryption methods fails to connect after determining the encryption method for communication.

[0088] This application provides an encryption method selection method, apparatus, terminal device, and computer-readable storage medium. The method involves: determining a first encryption method for the terminal device; establishing a communication connection with a network device based on the first encryption method; determining that communication with the network device is interrupted; calculating a first score for the first encryption method and a second score for a second encryption method; and selecting a target encryption method from the first and second encryption methods based on the first and second scores.

[0089] In summary, the encryption method selection method in this application embodiment enables the terminal device to calculate the score of the selectable encryption methods when communication with the network device is abnormal, and select the target encryption method to establish a communication connection based on the score. This achieves the technical effect of switching to another encryption method to attempt to repair the communication connection when the selected encryption method fails to establish a communication connection, thereby improving the user experience and meeting user needs.

[0090] The following sections provide detailed descriptions of each example. It should be noted that the order in which the embodiments are described is not intended to limit the priority of the embodiments.

[0091] Please refer to Figure 1, which is a schematic diagram of a scenario illustrating the encryption method selection method provided in this application embodiment. The encryption method selection system may include a terminal device 100 and a processing module 200. The terminal device 100 and the processing module 200 can communicate with each other in any way, including but not limited to signal communication via electronic circuits or wireless signals. Wireless signals can be computer network communication using the TCP / IP protocol suite (TCP / IP) or User Datagram Protocol (UDP). The terminal device 100 can receive control signals from a remote control or control panel, and it can also receive instruction information sent by the processing module 200. The terminal device 100 can perform corresponding operations based on the corresponding instruction information.

[0092] In this embodiment of the application, the terminal device 100 includes, but is not limited to, devices such as laptops, smartphones, and tablets that can connect to a wired network via a wireless access point.

[0093] Those skilled in the art will understand that the application environment shown in Figure 1 is only one application scenario of the present application solution and does not constitute a limitation on the application scenario of the present application solution. Other application environments may include more or fewer terminal devices than those shown in Figure 1. For example, only one terminal device is shown in Figure 1, but this is not specifically limited here.

[0094] In addition, as shown in Figure 1, the processing module 200 may include any hardware device capable of data processing and instruction sending, such as a CPU or microcontroller embedded in the terminal device; no specific limitation is made here.

[0095] It should be noted that the scenario diagram of the encryption method selection system shown in Figure 1 is merely an example. The encryption method selection system and scenario described in the embodiments of this application are intended to more clearly illustrate the technical solutions of the embodiments of this application and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of encryption method selection systems and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0096] Specifically, please refer to Figure 2, which is a schematic diagram of a scenario in which a terminal device according to an embodiment of this application executes the encryption method selection method. The specific execution process of the terminal device executing the encryption method selection method is as follows:

[0097] S201: Determine the first encryption method for the terminal device.

[0098] In this embodiment, the terminal device can periodically scan for network devices in the surrounding environment, match the network device to be connected using the BSSID of the wireless access point, and determine a suitable encryption method as the first encryption method by reading the Capabilities variable (a variable representing the functionality or capability of a system, device, or program) from the scanned data of the wireless access point. For example, if the variable contains PSK, it indicates that the encryption method supports WPA2; as another example, if the variable contains SAE, it indicates that the encryption method supports WPA3. Furthermore, it can be determined whether the network device uses WPA2 / WPA3 hybrid encryption by judging whether both PSK and SAE are present.

[0099] It should be noted that the terminal device in this embodiment supports WPA2 / WPA3 hybrid encryption, and the network device in this embodiment also supports WPA2 / WPA3 hybrid encryption. Only when both the terminal device and the network device support hybrid encryption can the user be provided with the option to choose an encryption method.

[0100] It should also be noted that the hybrid encryption method can be a combination of multiple different encryption methods. In this embodiment, only the case of WPA2 / WPA3 hybrid encryption is used as an example. In practical applications, it can also be a hybrid encryption method composed of other encryption methods, such as WPA / WPA2, WPA2 / WPA3, WEP / WPA / WPA2, etc.

[0101] In this embodiment of the application, when the terminal device matches the network device to be connected and determines that both the terminal device and the network device support hybrid encryption, the first encryption method to be used in this communication connection is first determined.

[0102] Optionally, the encryption method selection method provided in this application embodiment further includes: when the terminal device has a preset encryption method, determining the preset encryption method as the first encryption method.

[0103] In this embodiment of the application, taking the case of WPA2 / WPA3 hybrid encryption as an example, the preset encryption method includes at least one of the following: WPA2 method, or WPA3 method. As shown in Figure 3, which is a schematic diagram of the overall process of the encryption method selection method, if the terminal device has a preset encryption method, the preset encryption method can be directly selected as the first encryption method to enable the terminal device to establish a communication connection with the network device.

[0104] Optionally, if the terminal device and the network device are not establishing a communication connection for the first time, and a previous communication connection was established using WPA2 encryption, with WPA2 set as the default encryption method (marking WPA2 as a fixed encryption method for the network device), then in this communication connection, WPA2 can be directly selected to establish a communication connection with the network device.

[0105] Correspondingly, if WPA3 encryption was selected in a previous communication connection and set as the default encryption method (marking WPA3 as a fixed encryption method for the network device), then WPA3 can also be directly selected to communicate with the network device in this current communication connection.

[0106] As an optional embodiment, if the terminal device and the network device are establishing a communication connection for the first time, and the terminal device determines that WPA2 is the best encryption method based on information obtained from scanning the network device, then WPA2 can be directly set as the preset encryption method. That is, WPA2 is marked as a fixed encryption method for the network device, and the current communication connection can be directly encrypted using WPA2. WPA3 is also applicable.

[0107] Optionally, the encryption method selection method provided in this application embodiment further includes: determining the initial state of the target control of the terminal device when there is no preset encryption method in the terminal device; and determining the first encryption method based on the initial state.

[0108] In this embodiment of the application, as shown in Figure 3, if the terminal device does not have a preset encryption method, that is, the terminal device has not marked a fixed encryption method for the network device, the initial state of the target control of the terminal device is determined, and then the first encryption method is selected from the selectable encryption methods according to the initial state of the target control.

[0109] It should be noted that the target control can be set in the Wi-Fi settings interface of the terminal device, such as the "Maximum Compatibility" control. The terminal device can record and read the state of this control. When maximum compatibility is enabled, WPA2 will be given priority when connecting to WPA2 / WPA3 network devices. When maximum compatibility is disabled, WPA3 will be given priority when connecting to WPA2 / WPA3 network devices.

[0110] Optionally, the encryption method selection method provided in this application embodiment further includes: determining WPA2 as the first encryption method when the initial state of the target control is open; and determining WPA3 as the first encryption method when the initial state of the target control is closed.

[0111] In this embodiment of the application, the system of different terminal devices can set the initial default state of this control according to the needs of the system or user, including: on state and off state.

[0112] As an optional embodiment, taking a smartphone as an example, users can enable or disable the "maximum compatibility" control as needed. For example, to ensure stable communication, the control can be enabled, and when maximum compatibility is enabled, WPA2 will be prioritized when connecting to network devices. Conversely, to ensure information security during communication, the control can be disabled, and when maximum compatibility is disabled, WPA3 will be prioritized when connecting to network devices.

[0113] As an optional embodiment, taking a smartwatch as an example, the smartwatch may not have a Wi-Fi settings interface. In this case, the user cannot manually enable or disable the "maximum compatibility" control. However, the terminal device can automatically control the "maximum compatibility" control to be enabled or disabled based on its own system configuration. Similarly, when maximum compatibility is enabled, WPA2 is preferentially used when connecting to network devices; when maximum compatibility is disabled, WPA3 is preferentially used when connecting to network devices.

[0114] It should be noted that when connecting, if the network device is marked with a fixed encryption method (preset encryption method), the maximum compatibility switch state will not be considered. That is, the priority of marking a fixed encryption method is higher than the priority of the maximum compatibility switch logic.

[0115] S202: Establish a communication connection with the network device according to the first encryption method.

[0116] In this embodiment of the application, after determining the first encryption method, a communication connection is established with the network device using the first encryption method to perform data interaction.

[0117] It should be noted that the encryption method in the communication connection process, that is, the Wi-Fi connection process, refers to a technology used to protect the security of data transmission in the wireless network. The encryption method defines how data is encrypted and decrypted in the wireless network to prevent unauthorized access and data leakage.

[0118] S203: Determine if communication with the network device is interrupted, calculate a first score for the first encryption method, and calculate a second score for the second encryption method.

[0119] In this embodiment, as shown in Figure 3, when a connection fails using an encryption method—that is, when the first encryption method fails—an encryption method scoring mechanism is activated. Points are added to either the first or second encryption method based on the configuration information, and points are deducted for connection failures. The scores of different encryption methods are compared. If the highest-scoring encryption method remains unchanged from the currently used encryption method, a reconnection is triggered directly; if the highest-scoring encryption method has changed, a different encryption method is used to attempt a connection.

[0120] It should be noted that connection failures include not only unsuccessful connection attempts, but also communication interruptions, data encryption / decryption failures, and other situations affecting data interaction. Configuration information refers to details such as whether a preset encryption method exists and whether the target control is enabled.

[0121] Optionally, the encryption method selection method provided in this application embodiment further includes: calculating a first score and a second score based on one or more of the following: communication interruption between the terminal device and the network device, whether the first encryption method is a preset encryption method, or the initial state of the target control.

[0122] In this embodiment of the application, when the communication is interrupted in the first encryption method, the score of the first encryption method can be reduced. In addition, the first encryption method and the selectable second encryption method can be scored according to information such as the preset encryption method and the initial state of the target control.

[0123] Optionally, the encryption method selection method provided in this application embodiment further includes: reducing the first score by a first value when communication between the terminal device and the network device is interrupted; increasing the first score by a second value when the first encryption method is a preset encryption method; increasing the first score by a third value according to the initial state of the target control, or increasing the second score by a third value.

[0124] In this embodiment, when one or more abnormal situations such as communication interruption or connection failure occur between the terminal device and the network device, the first score corresponding to the first encryption method is reduced by a first value. It is then determined whether the first encryption method is a preset encryption method; if so, the first score corresponding to the first encryption method is increased by a second value.

[0125] It should be noted that terminal devices can also set the same or different initial scores for different encryption methods.

[0126] Optionally, taking an initial score of 10 points as an example, when one or more abnormal situations occur, such as communication interruption or connection failure, between the terminal device and the network device, the first score corresponding to the first encryption method is reduced by 30 points. If the first encryption method is a preset encryption method, the first score is increased by 50 points. If there is no preset encryption method, neither the first nor the second score is increased. Further, based on the initial state of the target control, it is determined whether a third value is added to the first score of the first encryption method or the second score of the second encryption method.

[0127] It should be noted that the above scores are for illustrative purposes only, and the scores may be modified or adjusted according to the actual situation during application.

[0128] Optionally, the encryption method selection method provided in this application embodiment further includes: adding a third value to the first score when the initial state of the target control is open and the first encryption method is WPA2; adding a third value to the second score when the initial state of the target control is closed and the first encryption method is WPA2; adding a third value to the second score when the initial state of the target control is open and the first encryption method is WPA3; and adding a third value to the first score when the initial state of the target control is closed and the first encryption method is WPA3.

[0129] In this embodiment of the application, if the initial state of the target control is the open state and the first encryption method is WPA2, then a third value is added to the first score corresponding to the first encryption method (WPA2).

[0130] In this embodiment of the application, if the initial state of the target control is closed and the first encryption method is WPA2, then a third value is added to the second score corresponding to the second encryption method (WPA3).

[0131] In this embodiment of the application, if the initial state of the target control is the open state and the first encryption method is WPA3, then a third value is added to the second score corresponding to the second encryption method (WPA2).

[0132] In this embodiment of the application, if the initial state of the target control is closed and the first encryption method is WPA3, then a third value is added to the first score corresponding to the first encryption method (WPA3).

[0133] Optionally, taking an initial score of 10 points and WPA2 as the first encryption method as an example, when one or more abnormal situations such as communication interruption or connection failure occur between the terminal device and the network device, the first score corresponding to WPA2 is reduced by 30 points; if WPA2 is the preset encryption method, the first score is increased by 50 points; if the target control is initially in the open state, the first score is increased by 30 points; at this time, the total score of the first score is 60 points, and the total score of the second score is 10 points.

[0134] Optionally, taking an initial score of 10 points and WPA3 as the first encryption method as an example, when one or more abnormal situations such as communication interruption or connection failure occur between the terminal device and the network device, the first score corresponding to WPA3 will be reduced by 30 points; if there is no preset encryption method, neither the first nor the second score will be added; if the target control is initially in the open state, the second score will be added by 30 points; at this time, the total score of the first score is -20 points, and the total score of the second score is 40 points.

[0135] It should be noted that the above scores are for illustrative purposes only, and the scores may be modified or adjusted according to the actual situation during application.

[0136] S204: Select the target encryption method from the first encryption method and the second encryption method based on the first score and the second score.

[0137] In this embodiment of the application, as shown in Figure 3, after calculating the first score and the second score, the first score and the second score are compared. If the encryption method of the highest score has not changed, the first encryption method can be selected to directly trigger a reconnection; if the encryption method of the highest score has changed, the second encryption method can be switched to try to connect.

[0138] Optionally, the encryption method selection method provided in this application embodiment further includes: if the first score is greater than the second score, determining the first encryption method as the target encryption method and using the first encryption method as the preset encryption method; if the second score is greater than the first score, determining the second encryption method as the target encryption method and using the second encryption method as the preset encryption method.

[0139] In this embodiment of the application, if the first score is greater than the second score, the first encryption method is still used as the target encryption method for reconnection; if the second score is greater than the first score, the second encryption method is switched as the target encryption method for communication connection.

[0140] In addition, the terminal device can set the first encryption method or the second encryption method as the preset encryption method based on the calculated score.

[0141] Optionally, when attempting to connect using the second encryption method, if the connection is successful on the first attempt, the currently used second encryption method is recorded for the network device and marked as a fixed encryption method. As long as this network is not forgotten or cleared, subsequent connections will use the marked encryption method, thus achieving connection self-healing and ensuring the stability of subsequent connections.

[0142] Optionally, when a connection is successfully established, the first score corresponding to the first encryption method can be cleared, and the second score corresponding to the second encryption method can be cleared.

[0143] In this embodiment, a technical solution is implemented by determining a first encryption method for the terminal device; establishing a communication connection with the network device based on the first encryption method; determining a communication interruption with the network device; calculating a first score for the first encryption method and a second score for the second encryption method; and selecting a target encryption method from the first and second encryption methods based on the first and second scores. This allows the terminal device to calculate the scores of selectable encryption methods and select a target encryption method for communication connection when a communication connection with the network device is abnormal. This achieves the technical effect of switching to another encryption method to attempt to repair the communication connection when the selected encryption method is abnormal, thereby improving user experience and meeting user needs.
