  • Method and system for secure authentication in a wireless network
    Patent number: 7849314
    Abstract: A method and a system for secure authentication in a wireless network are provided. The method comprises the following steps. First, a network device and a client device of a wireless network authenticate each other with EAP-TLS. Wherein, the network device mentioned above is a gateway or an access point. Then, the network device and the client device generate a TLS master secret jointly. In addition, the method uses a distributed mechanism to prevent the consequences of the failure of a single AAA server, and to alleviate the consequences resulting from a violated network device. Furthermore, the method includes a multiple time digital signature mechanism achieved by performing multiple times of one-way hash operation to enable verification and revocation of certificate.
