摘　　要：L-MAKEP协议是一种适用于非对等的无线网络的高效的密钥交换协议,该协议具有执行简单且计算复杂度低的优点。分析对比三种攻击方法,表明协议不能抵抗伪造和欺骗攻击,并指出安全问题在于其中的异或运算和公钥身份信息性验证的缺失。因此,在Yang-Chen方案的基础上采用身份密码系统,以身份信息作为用户的公钥,并在等式验证公式中引入公钥身份信息,从而实现双方的身份信息验证。同时增加了哈希确认来对弱客户端进行确认。协议的分析表明,改进协议能够正确执行,同时其安全性得到提高。L-MAKEP Protocol is an efficient key exchange protocol that is suitable for the equivalence wireless network, which has the advantages of simple implementation and low computational complexity. Analysis and comparison of three kinds of attacks indicates that the protocol doesn＇t overcome the forgery and spoofing attacks, and it is pointed out that security problem is to lack of XOR operation and doesn＇t verifying the public key. The refore, an improved Key Exchange Protocol which cancels the XOR operation and applies the identity information based on the Yang-Chen program was put forward. At the same time it increase the hash to confirm the weak client to confirm. The analysis of the protocol indicated that the improved protocol can be executed correctly and more security.
