| Abstract: | This paper first points out the flaws of traditional password-based challenge-response mechanism in wireless network authentication,and then proposes the EAP-TTLS protocol.The network architectural model and the authentication procedure of the EAP-TTLS protocol are analyzed,with focus on the tunneled authentication,ciphersuit negotiation,key material exchange and the key hierarchy.Finally,the comparison of EAP and EAP-TTLS is done,and based on EAP-TTLS＇s advantage and WiMAX network＇s characteristic,the application of EAP-TTLS in the WiMAX network is suggested,and the feasibility is also analyzed in detail. |
