Because cross-realm C2C-PAKE (client-to-client password authenticated key exchange) protocols can not resist some attacks, this paper writes up new attacks on two representative protocols, then designs a new cross-realm C2C-PAKE protocol with signature and optimal number of rounds for a client (only 2-rounds between a client and a server). Finally, it is proved that the new protocol can be resistant to all known attacks through heuristic analysis and that it brings more security through the comparisons of security properties with other protocols. 相似文献

一种改进的跨域口令密钥交换协议 总被引:1,自引:0,他引:1
跨域的端到端的口令认证密钥交换(C2C-PAKE)协议,可实现不同区域的两个客户通过不同的口令协商出共享的会话密钥.首先对Byun2007的C2C-PAKE协议进行了描述,并针对其安全性进行了分析,发现该协议易遭受口令泄露伪造攻击的安全漏洞,提出了一种高效的改进的跨域口令认证密钥交换协议.该协议引入公钥密码体制能够有效抵抗口令泄露伪造攻击和不可检测在线字典攻击,且只需要6步通信.安全性分析表明该协议是安全有效的. 相似文献
