摘要： A method and a system for authenticating an entity based on a symmetric encryption algorithm are provided. The method includes the following steps: 1) an entity A sends an authentication request message to an entity B; 2) after receiving the authentication request message, the entity B sends an authentication response message to the entity A; 3) the entity A determines the validity of the entity B according to the received authentication response message. The implementation cost of the system can be reduced by using the authentication according to the invention.

摘要： The present invention relates to a method for the secure access of mobile terminal to the Wireless Local Area Network (WLAN) and for secure data communication via wireless link, which, combining the common key encryption technology and the symmetry encryption technology, has resolved the failure in WLAN to provide effective control on secure MT access, and overcome the limitation on the confidentiality of the data communication via wireless link. When MT logs on AP, both parts must perform the certificate authentication through AS. Only the MT holding the legitimate certificate can access to AP holing the legitimate certificate; MT and AP perform the negotiation of common key for conversation, complete the dynamic revision of the secret key in each authentication, each secret key and in the process of conversation to achieve confidential data communication. Anyway, the method has not only achieved control on the access of MT, but also ensured the security of MT access and high confidentiality of communication.
