移动可信接入轻量级认证与评估协议

为增强移动终端可信网络接入认证与评估协议的可用性，降低网络通信负载及终端计算负载，提出一种轻量级的身份认证与平台鉴别评估协议。协议基于接入双方在首次接入时共享的认证密钥以及对方的可信平台配置信息，在不需要可信第三方参与的情况下，完成快速的身份认证与鉴别评估。协议减少了网络数据交换次数以及接入双方的计算工作量，在保证接入认证与评估所需的安全属性的同时，还增强了平台配置信息的机密性以及抵抗重放攻击的能力。安全性和性能分析表明，所提协议适合无线网络通信环境下的移动终端可信网络接入。

Lightweight authentication and evaluation protocol for mobile trusted access

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.
