摘 要: | 对现有的一个典型的基于验证元的三方密钥交换协议——ZZJ协议进行分析,指出它的不安全性。在此基础上针对现有的大多数基于验证元的3PAKE协议均难以抵御服务器密钥泄露攻击的现状,提出一个新的基于验证元的三方密钥交换协议——NZZJ协议。通过安全性分析,证明该协议能够抵御服务器密钥泄露攻击、未知密钥共享和内部人攻击等常见的安全威胁。

Abstract: | Presents security analysis of a veriiier-based key exchange protocol for three-party and points out that it is insecure. In the fact of that most of existing verifier-based 3PAKE protocols can not resist server key disclosure attack, presents an improved protocol. Though secu- rity analysis, this protocol can be proved to resist server key disclosure attack, unknown shared key and insider attack an so on common security threats. |
