中文摘要：
无线传感器网络（WSN）中的移动节点缺乏可信性验证,提出一种物联网（IoT）环境下移动节点可信接入认证协议。传感器网络中移动汇聚节点（Sink节点）同传感器节点在进行认证时,传感器节点和移动节点之间完成相互身份验证和密钥协商。传感器节点同时完成对移动节点的平台可信性验证。认证机制基于可信计算技术,给出了接入认证的具体步骤,整个过程中无需基站的参与。在认证时利用移动节点的预存的假名和对应公私钥实现移动节点的匿名性,并在CK（Canetti-Krawczyk）模型下给出了安全证明。在计算开销方面与同类移动节点认证接入方案相比,该协议快速认证的特点更适合物联网环境。
英文摘要：
In view of the problem that mobile nodes lack trusted verification in Wireless Sensor Network （WSN）, a mobile node access authentication protocol was proposed in Internet of Things （IoT）. Mutual authentication and key agreement between the sensor nodes and mobile sink nodes were realized, when they wre authenticated. At the same time, the trustness of mobile node platform was authenticated by sensor nodes. The authentication scheme was based on trusted computing technology without using base station and its concrete steps were described in detail. Pseudonyms and the corresponding public/private keys were used in authentication to achieve the protection of the user privacy. The proposed scheme was provably secure in the CK （Canetti-Krawczyk） security model. Compared to similar mobile node schemes, the protocol is more suitable for fast authentication in IoT, with less computation and communication overhead.
