一种改进的基于移动通信的论证密钥协商协议——MAKAP^+

AN IMPROVED MUTUALLY AUTHENTICATED KEY AGREEMENT PROTOCOL——MAKAP^+ BASED ON MOBILE COMMUNICATION

针对移动通信中的可证安全的双向密钥认证协议MAKAP协议的缺陷——不能抵御未知密钥共享攻击,给出了一个改进后的MAKAP+协议,在随机预言机模型中证明了本协议的安全性。改进后的协议不使用任何加密解密算法,具有更高的可靠性。通过性能分析,证明了此协议的实用性。

A security-provable mutually authenticated key agreement protocol—MAKAP of mobile communication has security flaw：it can not resist unknown key-share attack.To solve this problem,this paper proposes an improved protocol—MAKAP＋ protocol.In the random oracle model,this protocol has been proved its security.The improved protocol doesn＇t depend on any encoding/decoding algorithm and is more reliable.Through the analysis of its performance,the practicality of MAKAP＋ protocol has been proved.
