Abstract: For enhancing the usability of the authentication and evaluation protocol for mobile terminal trusted network access and reducing the overload of network communication and terminal calculation, a lightweight authentication and evaluation protocol was proposed. Depending on the authentication shared key and platform configuration information at the first access time, the both parties of communication could complete quick authentication and evaluation without trusted third party. The proposed protocol reduced the times of data switch and computing task, it not only ensured the security attributes of authentication and integrity verification, but also enhanced the privacy of platform configuring information and the ability of avoiding replay attack. The security and performance analysis shows that the proposed protocol adapts to mobile trusted access for wireless network.
