Embodiment approach
[0053] The following example illustrates the specific implementation, see Figure 3:
[0054] 1) After the Monitor device establishes a communication channel with the AP, it sends a message Monitor-AP-1 to the AP. The format of Monitor-AP-1 is as follows:
[0055] Monitor-AP-1 = MonitorID, EncMonitor_key(tmpkey, Monitor_time, MonitorID, ch).
[0056] Where MonitorID is the identification number of the Monitor device, ch is a random number randomly generated by the Monitor, and tmpkey is a random key generated by the Monitor.
[0057] 2) Since the AP does not have the key Monitor_key of the Monitor device, it cannot decrypt it, and generates a message AP-Auth-1 to the Monitor authentication server. The format of AP-Auth-1 is as follows:
[0058] AP-Auth-1 = Monitor-AP-1.
[0059] 3) The authentication server first authenticates the AP (that is, the user User). After the authentication is successful, it shares a key session_key with the AP. The authentication server queries the...

[0082] 1. Registration process
[0083] 1) The user registers his user name in AuthServer, sets a password, and is assigned the unique PID of the system. AuthServer saves the key User_key shared with the user.
[0084] 2) The application server AppServer also registers its own service Service with AuthServer, and shares a key Server_key with AuthServer.
[0085] 2. AP obtains Ticket from AuthServer
[0086] 1) When the user logs in from the AP, the user provides the user name, PID, password, and the application service to be used. The AP generates the user key User_key according to the user name, PID, and password, generates a random number Nonce, and combines it into a message AP-AuthServer- 1 to AuthServer, the format of AP-AuthServer-1 is as follows:
[0087] AP-AuthServer-1 = PID, Service, Nonce, AP_time, Hmac User_Key (PID, Service, Nonce, AP_time)
[0088] 2) AuthServer receives AP-AuthServer-1, decrypts the encrypted part, and verifies whether the data packet is cor...
