摘要
摘要:针对当前雾计算环境下终端节点的切换认证协议在存储量、计算量和安全性等方面还存在缺陷，该文提出一种高效的终端节点切换认证协议。在该协议中，采用双因子组合公钥(TF-CPK)和认证Ticket相结合的方式，实现雾节点和终端节点的相互认证和会话密钥协商。安全性和性能分析结果表明，该协议支持不可跟踪性，可以抵抗众多已知攻击和安全威胁，且具有较小的系统开销。

Abstract:In order to solve the problem that the switching authentication protocol of terminal nodes in fog computing has some defects in storage, compute and security, an efficient terminal node switching authentication protocol is proposed. In this protocol, mutual authentication and session key agreement between the fog nodes and terminal nodes are realized by the combination of Two Factors Combined Public Key(TF-CPK) and authentication ticket. The security and performance analysis results show that the protocol supports untraceability, which can resist numerous known attacks and security threats, and has a smaller system overhead.
