无线网络下可信移动节点接入认证方案

摘要

将基于属性且无可信第三方的平台验证协议以及基于身份的加密协议应用到无线网络环境下节点接入认证模型中,提出一个无线网络环境下的可信移动节点接入认证方案.与现有的认证方案相比,基于可信平台的移动节点接入认证方案主要有以下特点:1)在验证移动节点用户身份的同时也验证了移动节点的平台身份；2)不仅提供了移动节点和网络代理间的双向认证,还提供了移动节点间的双向认证.分析表明,改进后的方案满足接入节点身份的匿名性.%The platform authentication protocol based on the property without the third party and the encryption protocol based on identity were applied to the node authentication scheme under the wireless networks. Compared with the existing methods, the proposed trusted mobile node access scheme has two major features: 1) both the mobile platform identity and the mobile user identity are verified at the same time; 2) the mutual attestation not only between the mobile user and the network Agent, but also between the mobile users are provided. Analysis shows that the improved scheme can meet the anonymous requirement.
