摘要
针对孙达志等提出的群组证明协议进行重点分析,指出协议存在无法抗穷举攻击的安全缺陷,并在此基础上给出一个改进的协议。协议采用遍历取反运算对信息加密,遍历取反运算将根据加密参量自身汉明重量大小不同而进行对不同参量的取反操作,增加破解难度;协议将信息加密之后再发送,同时信息加密时确保多个参量攻击者无法知晓,以此来抵抗穷举攻击。从安全性角度分析协议,表明协议具有较好的安全性能;从仿真实验角度分析协议,表明协议具有计算量低的优势。
This paper focused on the analysis of the group proof protocol proposed by reference[10]and pointed out that the security defect of protocol could not resist the exhaustive attack.On this basis,an improved protocol was proposed.The protocol encrypted information by traversal inversion operation,which reversed the encryption parameters according to their Hamming weight and increased the difficulty of cracking.The protocol encrypted information before sending it,and ensured that the attacker of multiple parameters could not know the information when encrypting the information,so as to resist exhaustive attacks.Analysis of the protocol from the perspective of security shows that the protocol has good security performance;from the perspective of simulation experiments,it shows that the protocol has the advantage of low computation.
