摘　　要：物联网感知层的节点资源有限、设备脆弱、数据复杂,使得感知层安全问题层出不穷。感知层的数据可信与安全是保障整个物联网系统安全运行的基础。文章结合可信计算与环签密技术,提出一种适用于物联网感知层节点的可追踪成员身份的匿名认证方案,该方案在对外提供证明的同时能够隐藏节点的隐私信息,在数据存疑时可通过可信第三方进行身份追踪。文章最后通过理论分析和对比实验证明了该方案的正确性和高效性。The limited node resources,fragile devices,and complex data of the perception layer of the Internet of things make the security problems of the perception layer emerge in endlessly.Ensuring the credibility and security of the data in the perception layer is the basis to ensure the safe operation of the entire Internet of things system.Combining trusted computing and ring signcryption technology,this paper proposed an anonymous authentication scheme for traceable membership of nodes in the perception layer of the Internet of things.This scheme can hide the privacy information of nodes while providing external proof and can track the identity through a trusted third party when the data is in doubt.In addition,the correctness and effectiveness of this scheme are verified by simulation experiments,and the theoretical analysis shows that this scheme is efficient.
