一种自证明身份密钥协商协议的研究

针对Diffie-Hellman密钥协商协议易受中间人（man in the middle）攻击的问题，提出了一种自证明身份的密钥协商协议，阐述了密钥交换原理，分析了其安全性和实现的关键技术。该协议将RSA与离散对数相结合，使通信双方在不需对方公开密钥证书，不需数字签名，也不需密钥分配中心（KDC）的条件下进行双向身份认证，并同时产生共享的会话密钥，具有一定实用价值。

Research on self-certified identity encrypt key agreement protocol

In allusion to Diffie-Hellman encrypt key agreement protocol is subject to attack of man in the middle,this paper proposes a self-certified identity encrypt key agreement protocol,illustrates its encrypt key exchange principle,and analyses its security and key technology at the time of implementation.The protocol makes both communication sides authenticate each(other) and generates the same encrypt key without each(other's) public key certification,digital signature or the key distributed center(KDC),based on combination of RSA the with discrete logarithm,and is suitable for some applications.
