摘要
利用对无证书密钥协商协议常见的攻击方法,分析了两个无证书两方认证密钥协商协议的安全性.基于不同秘密信息泄露情况,分别对两个协议给出了密钥泄露伪装攻击、临时密钥泄露攻击等多种攻击方法.结果表明,两个协议都存在严重的安全缺陷.
Combined with common attack methods against certificateless authenticated key agreement proto- cols, this paper analyzes two certificateless authenticated key agreement protocols proposed by Liu et al. and Yang et al. respectively. Based on the different leakage of secret information, this paper presents various attacks against two certificateless authenticated key agreement protocols, such as key compromise impersonation attack and ephem- eral key compromise attack. The results show that both of two certificateless authenticated key agreement protocols are insecure.
