Abstract :
Mutual authentication and session key exchange protocols based on certificates for the wireless mobile communication/computing system are proposed. First, two improved versions for the conventional certificate-based systems are proposed, and an offline authentication mechanism based on the dynamic certificate is introduced. Then, an end-to-end internetwork-authenticated session key exchange protocol, which preserves a private communication between two mobile users, is finally proposed. In designing the security protocols proposed, the low computational power of the mobile stations and the low bandwidth of the wireless networks are considered
