【摘要】：为解决无线通信网络中不同用户之间的通信安全问题,通常会采用身份认证协议来确保通信双方身份的合法性。该认证协议应能抵抗重放攻击、延时攻击等威胁,同时认证过程中的计算量应尽量小。本文针对SEAHA(secure and efficient handover authentication)认证方案存在的计算量大、不能抵抗伪装攻击的问题提出了一种基于双线性对和离散对数难题(DLP)的无证书两方认证协议。该协议中基站和节点共同生成节点密钥对来抵抗伪装攻击,利用离散对数难题生成会话密钥降低认证过程中的计算量。安全分析和性能分析结果表明,提出协议在保证安全性的前提下,有效降低了认证过程中的计算量。
[Abstract]:In order to solve the problem of communication security between different users in wireless communication network, identity authentication protocol is usually adopted to ensure the legitimacy of the identity of both parties. The authentication protocol should be able to resist threats such as replay attack, delay attack and so on. At the same time, the computation in authentication process should be as small as possible. In order to solve the problem that SEAHA (secure and efficient handover authentication) authentication scheme can not resist camouflage attack, a certificateless bipartite authentication protocol based on bilinear pair and discrete logarithmic problem (DLP) is proposed. In this protocol, the base station and the node jointly generate the node key pair to resist the camouflage attack, and the discrete logarithmic problem is used to generate the session key to reduce the computation in the authentication process. The results of security analysis and performance analysis show that the proposed protocol can effectively reduce the computational complexity in the authentication process on the premise of ensuring security.
