TSM (Trusted Service Manager, Reliable Servo Management Platform) is a system platform that implements space management, application management and air card issuance for secure carriers with secure storage, computing, and anti-attack capabilities. It is used for offline mobile payment through NFC and other technologies. , access control and other servos provide the basis for implementation. TSM can realize reliable data transmission and over-the-air access to servo applications. For example, according to the user's choice, a city's transportation card can be loaded over the air through the security chip set in the mobile phone, and the transportation card can be recharged. At the same time, in the NFC ecosystem, TSM also acts as a middleman between publishers and server providers, users, and other participants, making the development of server applications faster and more secure. In the current reliable server management platform, the TSM server transmits data packets to the security chip in the Internet of Things (IoT) device through the wireless access point, and the terminal device passes the wireless access point to the security chip. The execution result of the data message is passed to the TSM server, and the data message transmission is repeated between the TSM server and the security chip in the terminal device until all data messages are transmitted, that is, the TSM server The operation of the security chip in the terminal device is completed, for example, the TSM server completes the over-the-air card issuance in the security chip of the terminal device. However, in practical applications, the terminal device will also be displaced with the change of the user's location. If the terminal device is displaced during the transmission of multiple data packets, for example, from the wireless network coverage of a wireless access point Roaming occurs when you move within the wireless network coverage of another wireless access point. During roaming, the terminal device will lose the connection of the old wireless access point, and at the same time will try to establish a connection with the new wireless access point, which is affected by many factors such as device performance, wireless access point performance, network conditions, etc., and For authentication reasons, switching from the old wireless access point to the new wireless access point will not only cause a delay of 1 to 5 seconds, but also may cause the connection between the TSM server and the terminal device to be interrupted, or even The loss of data packets will eventually lead to the failure of air card issuance.

In the following description, numerous specific details are set forth to facilitate a full understanding of the present case. However, this case can be implemented in many other ways different from those described here, and those skilled in the art can make similar promotions without violating the connotation of this case, so this case is not limited by the specific implementation disclosed below. This application provides a reliable server management method supporting wireless network switching, a reliable server management device supporting wireless network switching, another reliable server management method and device supporting wireless network switching, and two electronic devices. The following is a detailed description one by one with reference to the accompanying drawings of the embodiments provided in the present application, and each step of the method is described. An example of a reliable server management method for supporting wireless network handover provided by this application is as follows: Referring to FIG. 1, it shows a process flow diagram of an embodiment of a reliable server management method for supporting wireless network switching provided by this application. FIG. 2 shows a schematic diagram of a wireless network switching scenario provided by the present application. Referring to FIG. 3 , it shows a schematic diagram of a reliable server management installation process supporting wireless network switching provided by the present application. Step S101 , after detecting that the terminal device switches from the first wireless access point to the second wireless access point, notify the first wireless access point to cache the data message returned by the reliable server management platform for the server request. As shown in Figure 2, the TSM server (that is, the reliable server management platform) transmits data packets (APDU packets) with the terminal device through the wireless access point 1 (the first wireless access point, such as a Wi-Fi hotspot). During the process, the data messages often need to be sent to the security chip (SE) of the terminal device one by one or in batches for execution. During the execution process, the terminal device may cause changes to the connected wireless access point due to the change of the location, such as the terminal. The device roams from the wireless network coverage of wireless access point 1 to the wireless network coverage of wireless access point 2 (the second wireless access point). During this roaming process, when the terminal device moves to the overlapping area of the wireless network coverage of wireless access point 1 and wireless access point 2, the wireless network switching behavior before roaming will occur, that is, the terminal device Switching from wireless access point 1 to wireless access point 2 depends on many factors such as device performance, wireless access point performance, network conditions and other factors in the actual application scenario. This wireless network switching behavior takes 1 to 5 seconds. . During wireless network handover, the terminal device will lose connection with wireless access point 1, and try to establish a wireless connection with wireless access point 2, and switch from wireless access point 1 to wireless access point for authentication reasons 2. Not only the delay, but also the connection between the TSM server and the terminal device may be interrupted, or even the loss of data packets, which will eventually lead to the failure of the reliable server management process. The reliable server management method for supporting wireless network switching provided in this case, in order to ensure that data packets will not be lost during the wireless network switching process, and at the same time reduce the delay generated by the wireless network switching process, by connecting the terminal equipment in the wireless access process Switching back and forth between point 1 and wireless access point 2 not only ensures the connection between the terminal device and the TSM server through wireless access point 1, avoids the loss of data packets, and ensures the normal process of reliable server management; The connection between the terminal device and the wireless access point 2 remains normal, which reduces the delay caused by the wireless network handover process. The embodiment of this case is described by taking the application of over-the-air downloading in the process of reliable servo management or the creation of a security domain (ie, over-the-air card issuance) in SE as an example. As shown in Fig. 3, before the wireless network switching, the The first wireless link established between the access points 1 initiates a serving request to the TSM server and receives a data packet returned by the TSM server for the serving request based on the first wireless link. Preferably, the servo request refers to an over-the-air card issuance request, and the terminal device refers to an IoT device in the scenario of over-the-air card issuance. That is, before the IoT device switches from wireless access point 1 to wireless access point 2, the IoT device communicates with the TSM server through wireless access point 1. Specifically, the IoT device initiates OTA (Over The Air) through the TSM SDK. ) request, that is, an over-the-air card issuance request, such as a request for creating a security domain in the SE, installing an application over-the-air in the SE, etc. The wireless access point 1 forwards the OTA request to the TSM server. After receiving the OTA request, the TSM server processes the OTA request and generates the corresponding APDU command script, and sends the generated APDU command script to the wireless access point 1 one by one or in batches in the form of APDU packets, and then sent by The wireless access point 1 forwards it to the TSM SDK on the IoT device, and finally the APDU message is written into the SE for execution. It should be noted that, in the process of switching the IoT device from the wireless access point 1 to the wireless access point 2 in the embodiment of this case, the IoT device needs to be in the wireless network of both the wireless access point 1 and the wireless access point 2. within the overlapping area of the road coverage. Preferably, before switching from the wireless access point 1 to the wireless access point 2, the IoT device can also judge whether the signal strength of the wireless network of the wireless access point 2 is greater than that of the wireless access point 1 through the following judgment operation: If the signal strength of the wireless network is greater than that, switch the IoT device from the wireless access point 1 to the wireless access point 2; if the signal strength of the wireless network of the wireless access point 2 is less than or equal to the wireless access point 1 wireless The signal strength of the network can be re-detected and compared with the signal strengths of the wireless access point 1 and the wireless access point 2 after a delay of a certain time interval, and whether to switch or not is determined according to the comparison result. This embodiment can use the feature of the IEEE802.11 standard to support multi-channel communication to communicate with the wireless access point 1, and perform an authentication process on the wireless access point 2, so as to establish the Internet of Things device and the TSM server through the wireless access point 2 Connection. In a preferred implementation provided by the embodiment of this application, two modes (working mode and sleep mode) of the wireless access point for IoT devices are used to switch between the wireless access point 1 and the wireless access point 2. First, if the wireless access point 1 or the wireless access point 2 is in sleep mode for the IoT device, after the wireless access point 1 or the wireless access point 2 receives the APDU message sent by the TSM server, the APDU The message is stopped from forwarding to the IoT device, but the APDU message is cached locally by wireless access point 1 or wireless access point 2, which requires wireless access point 1 and wireless access point 2 to have cached APDUs function of the message. Second, if the wireless access point 1 or the wireless access point 2 is in the working mode for the IoT device, after the wireless access point 1 or the wireless access point 2 receives the APDU message sent by the TSM server, the The APDU message can be normally forwarded to the IoT device. For example, when the IoT device switches from wireless access point 1 to wireless access point 2, the IoT device authenticates with wireless access point 2 to establish a connection. If the mode of the device is set to sleep mode, the wireless access point 1 will cache the APDUs locally after receiving the APDUs sent from the TSM server. When the IoT device is switched from the wireless access point 2 to the wireless access point 1, the mode of the wireless access point 1 for the IoT device is switched from the sleep mode to the working mode. The fetch point 1 will forward the previously cached APDU packets to the IoT device. In this step, after detecting that the IoT device is switched from the wireless access point 1 to the wireless access point 2, the wireless access point 1 is notified to cache the data packet returned by the TSM server for the OTA request. For example, the mode of wireless access point 1 for IoT devices is switched from working mode to sleep mode, and the mode of wireless access point 2 for IoT devices is switched from sleep mode to working mode. After the mode switching, TSM servo The APDU message sent by the device to the IoT device is cached at the wireless access point 1, and sent to the IoT device after the wireless access point 1 returns to the working mode for the IoT device. Step S102, initiate an authentication operation to the reliable server management platform based on the second wireless access point. As mentioned above, the above step S101 switches the mode of the wireless access point 2 for the IoT device to the working mode. On this basis, in this step, an authentication operation is initiated to the TSM server through the wireless access point 2, so that the wireless access point 2 can pass the wireless access point. 2. Establish the connection between the IoT device and the TSM server to ensure that after the IoT device is finally switched to the wireless access point 2, the data message transmission between the IoT device and the TSM server can be maintained through the wireless access point 2. Preferably, the authentication operation can be performed by decomposing the authentication operation into a plurality of authentication stages, and before, during or after the execution of each authentication stage, at least one execution is performed to remove the IoT device from the wireless access point. 2 Switch back to the switching operation of wireless access point 1. In a preferred implementation provided by the embodiment of the present application, the authentication phase after the authentication operation is decomposed includes a first authentication phase, a second authentication phase and a third authentication phase, and in the first authentication phase, the second authentication phase After the authentication phase and the third authentication phase are executed, a switching operation of switching the IoT device from the wireless access point 2 back to the wireless access point 1 is performed respectively, and the specific execution sequence is as follows: the first authentication phase -> the The handover operation of switching the IoT device from the wireless access point 2 back to the wireless access point 1 -> the second authentication stage -> the handover operation of switching the IoT device from the wireless access point 2 back to the wireless access point 1 - >The third authentication phase->Handover operation to switch the IoT device from wireless access point 2 back to wireless access point 1 . (1) The first authentication stage is preferably implemented in the following manner: establishing a second wireless link between the IoT device and the wireless access point 2; sending the wireless access point 2 based on the second wireless link Send an authentication request; Receive an identification information acquisition request returned by the wireless access point 2 for the authentication request; Send a response frame to the wireless access point 2 in response to the identification information acquisition request; the response frame includes the IoT device corresponding identification information. For example, as shown in FIG. 3, in the first authentication stage, the wireless access point 1 enters the sleep mode for the IoT device. Therefore, after the wireless access point 1 receives the APDU message sent by the TSM server, the wireless storage Take point 1 to cache the APDUs sent by the TSM server locally. At the same time, when the wireless access point 2 enters the working mode for the IoT device, the IoT device initiates a connection request to the wireless access point 2, thereby establishing a wireless connection between the IoT device and the wireless access point 2, because the initial The status is unauthenticated, so at this time, the wireless access point 2 and the IoT device cannot receive and send any data packets except IEEE 802.1x protocol packets. After the wireless connection between the IoT device and the wireless access point 2 is established, the IoT device sends an authentication request (EAPOL-Start) to the wireless access point 2 through the wireless connection to start the authentication process. After receiving the authentication request from the IoT device, the wireless access point 2 sends an EAP request (EAP-Request/Identity) of the Identity (identity) type to the IoT device, asking the IoT device to send its identity to the wireless access point. point 2. After receiving the EAP request (EAP-Request/Identity) from the wireless access point 2, the IoT device sends the identification information to the wireless access point 2 through the EAP response frame (EAP-Response/Identity) of the Identity type. After the EAP request (EAP-Request/Identity) sent by the wireless access point 2, the wireless access point 2 sends the EAP response frame (EAP-Response/Identity) to the TSM server for processing. As shown in FIG. 3 , after the above-mentioned first authentication stage is completed, a switching operation of switching the IoT device from the wireless access point 2 to the wireless access point 1 is performed. For details, please refer to the following steps S103 to S105 for the description Detailed description of the toggle operation. (2) The second authentication stage is preferably implemented in the following manner: Receive a challenge message sent by the wireless access point 2; the challenge message includes a key for encrypting cipher information; encrypting the cipher information corresponding to the identification information; and sending a response message including the encrypted cipher information to the TSM server based on the second wireless link. For example, as shown in FIG. 3, in the second authentication stage, the wireless access point 1 enters the sleep mode for the IoT device. Therefore, after the wireless access point 1 receives the APDU message sent by the TSM server, the wireless storage Take point 1 to cache the APDUs sent by the TSM server locally. After the TSM server receives the request from the wireless access point 2 (that is, the EAP response frame (EAP-Response/Identity)), after extracting the identification information corresponding to the IoT device, the identification information is combined with the identification information in the database. Compare the identification information list, find the password information corresponding to the identification information, encrypt the password with a randomly generated MD5 Challenge message, and then encapsulate the MD5 Challenge message in the EAPOR format and send it to the wireless access via an Access-Challenge message. point 2. After receiving the Access-Challenge message in the EAPOR format from the TSM server, the wireless access point 2 forwards the MD5 Challenge message to the IoT device through decapsulation. After receiving the MD5 Challenge message (that is, the challenge message) forwarded by the wireless access point 2, the IoT device uses the Challenge message to encrypt the password part, and then generates an EAP-Response/MD5 Challenge message, which will be generated. The EAP-Response/MD5 Challenge message (ie the response message) is sent to the wireless access point 2. The wireless access point 2 encapsulates the EAP-Response/MD5 Challenge message in an EAPOR format in a message (Access-Request) and sends it to the TSM server. As shown in FIG. 3 , after the above-mentioned second authentication stage is completed, a switching operation of switching the IoT device from the wireless access point 2 to the wireless access point 1 is performed. For details, please refer to the following steps S103 to S105 for the description Detailed description of the toggle operation. (3) The third authentication stage is preferably implemented in the following manner: receiving an authentication pass message sent by the wireless access point 2; the authentication pass message is sent by the TSM server to the After the password information is verified, it is sent to the wireless access point 2; Receive the notification sent by the wireless access point 2 that its port is authorized to access the IoT device; Receive the polling message sent by the wireless access point 2; The polling message sends the corresponding polling response message to the wireless access point 2. For example, as shown in FIG. 3, in the third authentication stage, the wireless access point 1 enters the sleep mode for the IoT device. Therefore, after the wireless access point 1 receives the APDU message sent by the TSM server, the wireless storage Take point 1 to cache the APDUs sent by the TSM server locally. After receiving the Access-Request message containing the encrypted password information from the wireless access point 2, the TSM server compares it with the locally encrypted password information. The wireless access point 2 sends an authentication pass message (Access-Accept). After the wireless access point 2 receives the Access-Accept message, it decapsulates it through EAPOR and sends it to the IoT device in an EAP-Success message, and changes the port to the authorized state, allowing the IoT device to access through the port. In addition, while the connection between the IoT device and the wireless access point 2 is online, the wireless access point 2 will monitor the online status of the IoT device by periodically sending a Handshake Request (polling message) to the IoT device. After receiving the Handshake Request (polling message), the IoT device sends a Handshake Response (polling response message) to the wireless access point 2, indicating that the connection between the IoT device and the wireless access point 2 is still online. As shown in FIG. 3 , after the above-mentioned first authentication stage is completed, a switching operation of switching the IoT device from the wireless access point 2 to the wireless access point 1 is performed. For details, please refer to the following steps S103 to S105 for the description Detailed description of the toggle operation. During specific implementation, in addition to the above-mentioned method of decomposing the authentication operation into three authentication stages, the authentication operation can also be decomposed into one, two, four or even more authentication phases. The specific implementation manner is similar to the manner of decomposing the authentication operation into three authentication stages provided above. For example, decomposing the authentication operation into an authentication phase specifically includes: establishing a second wireless link between the IoT device and the wireless access point 2, and sending a message to the wireless access point 2 based on the second wireless link Authentication request, receive the identification information acquisition request returned by the wireless access point 2 for the authentication request, and send a response frame to the wireless access point 2 in response to the identification information acquisition request, where the response frame contains the corresponding identification information; receive a challenge message sent by the wireless access point 2, the challenge message includes a key for encrypting the password information, and the password information corresponding to the identification information is encrypted by using the key, based on the The second wireless link sends a response message including the encrypted password information to the TSM server; receives an authentication pass message sent by the wireless access point 2, the authentication pass message is sent by the TSM server to the response message The password information contained in the password is sent to the wireless access point 2 after the verification is passed, and the notification sent by the wireless access point 2 that its port is authorized to access the Internet of Things device is received. Step S103, switching the terminal device from the second wireless access point back to the first wireless access point. It should be noted that this step, the following step S104 and the following step S105 together constitute the switching operation of switching the IoT device from the wireless access point 2 back to the wireless access point 1. The precondition for performing the switching operation of switching the device from the wireless access point 2 back to the wireless access point 1 is after the first authentication phase, the second authentication phase and the third authentication phase are performed respectively. Specifically, as shown in FIG. 3 , the switching operation of switching the IoT device from the wireless access point 2 back to the wireless access point 1 is performed for the first time after the first authentication stage is performed, and The second authentication stage is performed before execution. The switching operation of switching the IoT device from the wireless access point 2 back to the wireless access point 1 is performed for the second time after the second authentication phase is performed and before the third authentication phase is performed.
