Abstract: A method and device for identity authentication. An authentication access controller (AAC) acquires an identity ciphertext message transmitted by a requesting device (REQ), the identity ciphertext message comprising an identity information ciphertext of the REQ, the AAC decrypts the identity information ciphertext of the REQ to generate a digital certificate (CertREQ) of the REQ, transmits a first authentication request message comprising the CertREQ to a first authentication server, and receives a first authentication response message transmitted by the first authentication server, the first authentication response message comprising authentication result information and a digital signature of the first authentication server, the AAC utilizes a public key of the first authentication server to verify the digital signature of the first authentication server, and if successfully verified, then the AAC determines an identity authentication result for the REQ on the basis of the verification result of the CertREQ in the authentication result information.

Abstract: A network device role self-adaptive method and apparatus are provided. Specifically, a first network device and a neighbor network device both determine their respective priority according to information including a connection result between the corresponding network device itself and a server; the first network device receives a second start frame which is sent by the neighbor network device and comprises the priority of the neighbor network device, and then determines whether its own priority and the priority of the neighbor network device meet preset conditions; and if yes, when the priority of the first network device is higher than the priority of the neighbor network device, the first network device determines its own role as an authentication access controller, and when the priority of the first network device is lower than the priority of the neighbor network device, the first network device determines its own role as a request device.

Abstract: A wireless network switching method. In the method, a station and a target access device directly generate a message integrity check key by means of a domain key, and verify an integrity code on the basis of the message integrity check key, so as to realize the authentication of two parties; and when the authentication of the opposite party is successful, session keys are generated by means of the domain key and in conjunction with random numbers of the two parties, thereby simplifying a switching process and realizing secure and efficient network switching. Further disclosed are a corresponding station and a corresponding access device.
