Abstract
A process for mutual authentication of users and networks over an unsecured wireless communication channel. In one embodiment, sensitive information (e.g., passwords) is not communicated over the unsecured channel. Rather, hashed representations of user identifiers, passwords, etc., and randomly generated numbers are communicated between the client and the network during the log-in process. The representations may be encrypted with a one-way hash function such that it is not computationally feasible for an eavesdropper to decrypt. In one embodiment, the representation may be generated based on the user identifier, password and/or MAC address of a wireless LAN card.
