Abstract: Identity authentication and key agreement are very important about security in wireless communications. The paper [4] proposed a wireless mutual authentication and key agreement protocol, but some secure flaws are found in that. So we proposed an analogous protocol based semi- anonymous XTR signcrypt algorithm, which is evaluated at last.

Key words: authentication, key agreement, signcryption algorithm, XTR, anonymous

摘要: 无线通信中,身份认证和密钥协商是一个重要的安全问题.本文首先指出文献[4]中构造的相关协议的安全漏洞和攻击方法;然后提出来一个半匿名基于XTR公钥体制的签密算法,基于该算法构造了一个高效的无线匿名认证和密钥协商协议;最后对该协议的安全性,计算量和通信量进行了评估.
