Description

Reliable servo management method and device supporting wireless network switching

This case relates to the field of reliable servo management, and specifically relates to a reliable servo management method that supports wireless network switching. This case also concerns a reliable servo management device that supports wireless network switching, another reliable servo management method and device that supports wireless network switching, and two types of electronic equipment.

TSM (Trusted Service Manager) is a system platform that implements space management, application management, and aerial card issuance on a secure carrier with secure storage, computing, and anti-attack capabilities. It provides offline mobile payment through NFC and other technologies. , Access control and other servos provide the basis for implementation. TSM can achieve reliable data transmission and air access for servo applications. For example, according to the user's choice, the traffic card of a certain city is loaded in the air through the security chip set in the mobile phone, and the traffic card is recharged. At the same time, in the NFC ecosystem, TSM also plays a middleman role between publishers and servo providers, users, and other participants, making the development of servo applications faster and more secure.
In the current reliable servo management platform, the TSM server transmits the data message to the security chip in the Internet of Things (IoT) device through the wireless access point, and the terminal device then passes the wireless chip to the security chip. The execution result of the data message is passed to the TSM server, so the data message transmission between the TSM server and the security chip in the terminal device is repeated multiple times until all the data messages have been 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 card issuance in the air in the security chip of the terminal device.
However, the terminal device in actual application will also shift with the change of the user's location. If the terminal device shifts during the transmission of multiple data messages, such as the wireless network coverage from a wireless access point Roaming occurs when you move to 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 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, and Due to authentication, switching from the old wireless access point to the new wireless access point will not only have a delay of 1 to 5 seconds, but may also cause the connection between the TSM server and the terminal device to be interrupted, or even The loss of data messages eventually led to the failure of card issuance in the air.

Numerous specific details are set forth in the description below to facilitate a full understanding of the case. However, this case can be implemented in many other ways than described here, and those skilled in the art can make similar promotion without violating the content of this case, so this case is not limited by the specific implementation disclosed below.
This case provides a reliable servo management method supporting wireless network switching. This case also provides a reliable servo management device supporting wireless network switching, another reliable servo management method and device supporting wireless network switching, and two electronic devices. The following describes each of the embodiments in detail with reference to the drawings of the embodiments provided in this case, and describes each step of the method.
An example of a reliable servo management method supporting wireless network switching provided in this case is as follows:
Referring to FIG. 1, it illustrates a processing flowchart of an embodiment of a reliable servo management method for supporting wireless network switching provided in this case, and with reference to FIG. 2, it illustrates a schematic diagram of a wireless network switching scenario provided in this case. Referring to FIG. 3, it shows a schematic diagram of a reliable servo management installation process supporting wireless network switching provided in the present case.
Step S101: After detecting that the terminal device is switched 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 servo management platform for the servo request.
As shown in FIG. 2, the TSM server (ie, the reliable servo management platform) transmits data messages (APDU messages) to the terminal device through the wireless access point 1 (the first wireless access point, such as a Wi-Fi hotspot). In the process, 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 connected wireless access point may change due to the change of location of the terminal device, 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 (second wireless access point). During this roaming process, when the terminal device moves to the overlapping area of the wireless network coverage of both wireless access point 1 and wireless access point 2, the wireless network switching behavior occurs before roaming, 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, and network conditions in the actual application scenario. This wireless network switching behavior takes 1 to 5 seconds . During the wireless network switching, the terminal device will lose the 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 due to authentication. 2. Not only is there a delay, but it may also cause the connection between the TSM server and the terminal device to be interrupted, or even the loss of data messages, which ultimately leads to the failure of the reliable servo management process. The reliable servo management method supporting wireless network switching provided in this case, in order to ensure that data messages are not lost during the wireless network switching process, and at the same time reduce the delay caused by the wireless network switching process, Switching back and forth between point 1 and wireless access point 2 not only guarantees the connection between the terminal device and the TSM server through wireless access point 1 but also avoids the loss of data messages and ensures the normal operation of the reliable servo management process. The connection between the terminal device and the wireless access point 2 remains normal, reducing the delay caused by the wireless network switching process.
The embodiment in this case uses the application of over-the-air downloading in the process of reliable servo management or the creation of a secure domain (that is, over-the-air card issuing) in the SE as an example. As shown in FIG. 3, before the wireless network switch, the terminal device and A first wireless link established between the access points 1 initiates a servo request to the TSM server and receives a data message returned by the TSM server for the servo request based on the first wireless link. Preferably, the servo request refers to a card issuing request in the air, and the terminal device refers to an Internet of Things device in the scenario of card issuing in the air. That is, before the IoT device is switched 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, a card issuance request in the air, such as a request for creating a security domain in the SE, and installing an application in the air in the SE, and 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 instruction script, and sends the generated APDU instruction script to the wireless access point 1 one by one or in batches in the form of APDU messages. The wireless access point 1 forwards it to the TSM SDK on the IoT device side, and the final 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 the present case, the IoT device needs to be in the wireless network of both the wireless access point 1 and the wireless access point 2. Road coverage within the overlapping area. Preferably, before switching from the wireless access point 1 to the wireless access point 2, the IoT device can also determine 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, the IoT device will be switched from wireless access point 1 to wireless access point 2; if the wireless signal strength of wireless access point 2 is less than or equal to wireless access point 1 wireless The signal strength of the network can be re-detected and compared after a delay of a certain time interval, and the signal strengths of both the wireless access point 1 and the wireless access point 2 can be compared, and whether to switch is determined based on the comparison result.
In this embodiment, the characteristics of the IEEE 802.11 standard supporting multi-channel communication can be used to communicate with the wireless access point 1, and perform an authentication process on the wireless access point 2, so as to establish an IoT device and a TSM server through the wireless access point 2. Connection. In a preferred implementation provided by the embodiment of the present case, the wireless access point is used to switch between the wireless access point 1 and the wireless access point 2 in two modes (working mode and sleep mode) for the IoT device. First, if the wireless access point 1 or the wireless access point 2 is in a sleep mode for the IoT device, after the wireless access point 1 or the wireless access point 2 receives the APDU message issued by the TSM server, the APDU The message is stopped being forwarded to the IoT device, but the wireless access point 1 or wireless access point 2 caches the APDU message locally. This requires wireless access point 1 and wireless access point 2 to have cached APDUs. The function of the message. Secondly, if the wireless access point 1 or wireless access point 2 is in the working mode for the IoT device, the wireless access point 1 or wireless access point 2 will receive the APDU message issued by the TSM server, and then The APDU message can be forwarded to the IoT device normally.
For example, when the IoT device is switched from the wireless access point 1 to the wireless access point 2, the IoT device authenticates with the wireless access point 2 to establish a connection. At this time, the wireless access point 1 is When the device mode is set to sleep mode, the wireless access point 1 will cache the APDU message locally after receiving the APDU message 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. Based on this, the wireless storage device Access point 1 will forward the previously cached APDU message 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 message returned by the TSM server in response to 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 switch is performed, TSM servo The APDU message sent from the device to the IoT device is cached at the wireless access point 1, and is sent to the IoT device after the wireless access point 1 resumes the working mode for the IoT device.
In step S102, an authentication operation is initiated to the reliable servo management platform based on the second wireless access point.
As described above, the above step S101 switches the mode of the wireless access point 2 for the IoT device to the working mode. Based on this step, the wireless access point 2 initiates an authentication operation to the TSM server through the wireless access point. 2 Establish a 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 wireless access point 2 and the TSM server can be maintained. Preferably, the authentication operation may be performed by decomposing the authentication operation into multiple authentication phases, and the IoT device is removed from the wireless access point at least once before, during, or after each authentication phase. 2 Switch back to the wireless access point 1 switching operation.
In a preferred implementation manner provided by the embodiment of the present case, 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 performed, a switching operation for switching the IoT device from the wireless access point 2 to the wireless access point 1 is performed respectively, and the specific execution sequence is as follows: the first authentication phase-> will Switching operation of IoT device switching from wireless access point 2 to wireless access point 1-> said second authentication phase-> switching operation of switching IoT device from wireless access point 2 to wireless access point 1- > The third authentication stage-> Switching operation of switching the IoT device from the wireless access point 2 back to the wireless access point 1.
(1) The first authentication phase is preferably implemented in the following manner:
Establishing a second wireless link between the IoT device and the wireless access point 2;
Sending an authentication request to the wireless access point 2 based on the second wireless link;
Receiving the identification information acquisition request returned by the wireless access point 2 in response to the authentication request;
A response frame is sent to the wireless access point 2 in response to the identification information acquisition request; the response frame includes identification information corresponding to the IoT device.
For example, as shown in FIG. 3, in the first authentication phase, the wireless access point 1 enters the sleep mode for the IoT device. Therefore, after receiving the APDU packet issued by the TSM server, the wireless access point 1 wirelessly stores the wireless access point 1. Fetch point 1 caches the APDU packets delivered by the local TSM server. 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 to establish a wireless connection between the IoT device and the wireless access point 2, because the original The status is unauthenticated, so at this time, no data packet can be received and sent between the wireless access point 2 and the IoT device except the IEEE 802.1x protocol packet.
After establishing a wireless connection between the IoT device and the wireless access point 2, 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 Identity type EAP request (EAP-Request / Identity) to the IoT device, and requests the IoT device to send its identity to the wireless access Point 2. After receiving the EAP request (EAP-Request / Identity) of the wireless access point 2, the IoT device sends the identification information to the wireless access point 2 through an Identity type EAP response frame (EAP-Response / Identity), and responds The EAP request (EAP-Request / Identity) sent by the wireless access point 2 is thereafter sent by the wireless access point 2 to the TSM server for processing the EAP response frame (EAP-Response / Identity).
As shown in FIG. 3, after the execution of the first authentication phase is completed, a switching operation for switching the IoT device from the wireless access point 2 to the wireless access point 1 is performed. For details, refer to steps S103 to S105 described below. A detailed description of the switching operation.
(2) The second authentication phase is preferably implemented in the following manner:
Receiving a challenge message sent by the wireless access point 2; the challenge message includes a key for encrypting password information;
Encrypting password information corresponding to the identification information by using the key;
Sending a response message including the encrypted password information to the TSM server based on the second wireless link.
For example, as shown in FIG. 3, in the second authentication phase, the wireless access point 1 enters the sleep mode for the IoT device. Therefore, after receiving the APDU message sent by the TSM server, the wireless access point 1 wirelessly stores the wireless access point 1. Fetch point 1 caches the APDU packets delivered by the local TSM server. After the TSM server receives the request from the wireless access point 2 (that is, the EAP response frame (EAP-Response / Identity)), it extracts the identification information corresponding to the IoT device from it, and then uses the identification information and the Compare the identification information list, find the password information corresponding to the identification information, and encrypt the password with a randomly generated MD5 Challenge message, and then encapsulate this MD5 Challenge message in the EAPOR format and send it in an Access-Challenge message to the wireless access Point 2. After receiving the EAPOR format Access-Challenge message from the TSM server, the wireless access point 2 decapsulates and forwards the MD5 Challenge message to the IoT device. 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. The EAP-Response / MD5 Challenge message (that is, the response message) is sent to the wireless access point 2. The wireless access point 2 encapsulates this 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 execution of the second authentication phase is completed, a switching operation for switching the IoT device from the wireless access point 2 to the wireless access point 1 is performed. For details, refer to steps S103 to S105 below. A detailed description of the switching 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 to the wireless access point 2 after the password information included in the response message is verified by the TSM server;
Receiving a notification from its wireless access point 2 that its port authorizes access to the IoT device;
Receiving a polling message sent by the wireless access point 2;
A corresponding polling response message is sent to the wireless access point 2 for the polling message.
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 receiving the APDU packet issued by the TSM server, the wireless access point 1 wirelessly stores the wireless access point 1. Fetch point 1 caches the APDU packets delivered by the local TSM server. After receiving the Access-Request message from the wireless access point 2 containing the encrypted password information, the TSM server compares the encrypted password information with the local encrypted operation. The wireless access point 2 sends an authentication-accept message (Access-Accept). After the wireless access point 2 receives the Access-Accept message, it de-encapsulates it and sends it to the IoT device as an EAP-Success message, and changes the port to an authorized state, allowing the IoT device to access through the port.
In addition, when the connection between the IoT device and the wireless access point 2 is online, the wireless access point 2 will periodically send a Handshake Request (polling message) to the IoT device to monitor the online status of the IoT device. The IoT device sends a Handshake Response (polling response message) to the wireless access point 2 after receiving the Handshake Request (polling message), which indicates that the connection between the IoT device and the wireless access point 2 is still online.
As shown in FIG. 3, after the execution of the above-mentioned first authentication phase, a switching operation for switching the Internet of Things device from the wireless access point 2 to the wireless access point 1 is performed. A detailed description of the switching operation.
In specific implementation, in addition to the implementation of the method for decomposing the authentication operation into 3 authentication phases, the method can also be performed by decomposing the authentication operation into 1, 2, 4, or even more authentication phases. The specific implementation manner is similar to the manner of decomposing the authentication operation into three authentication phases 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 the second wireless link to the wireless access point 2 based on the second wireless link. The authentication request receives the identification information acquisition request returned by the wireless access point 2 in response to the authentication request, and sends a response frame to the wireless access point 2 in response to the identification information acquisition request, and the response frame includes a corresponding response of the IoT device. Receiving the challenge information sent by the wireless access point 2, the challenge message includes a key for encrypting the password information, and using the key to encrypt the password information corresponding to the identifier information, 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, and the TSM server responds to the response message with the authentication pass message The password information contained in the password information is sent to the wireless access point 2 after receiving the pass, and the port sent by the wireless access point 2 is authorized to access the IoT device. .
Step S103: Switch the terminal device from the second wireless access point back to the first wireless access point.
It should be noted that this step and the following step S104 and the following step S105 collectively constitute a switching operation for switching the Internet of Things device from the wireless access point 2 to the wireless access point 1. In the embodiment of this case, the The premise of performing the switching operation of the device switching from the wireless access point 2 to the wireless access point 1 is after the execution of the first authentication phase, the second authentication phase, and the third authentication phase, respectively. Specifically, as shown in FIG. 3, the switching operation of switching the IoT device from the wireless access point 2 to the wireless access point 1 is performed for the first time, after the first authentication phase is performed, and The second authentication phase is performed before execution.
