摘　　要：针对Diffie-Hellman密钥交换协议缺乏对通信双方身份的认证而导致该协议易受到中间人攻击和重放攻击的问题,提出了一种改进的Diffie-Hellman密钥交换协议——AADH协议.性能分析表明,AADH协议由于引入了密钥认证及时间戳和随机的通信标号等机制、继承了Diffie-Hellman协议的安全性能,具有较高的抗中间人攻击和重放攻击的能力.Since the Diffie-Hellman key exchange protocol lacks the authentication for identity,it might be suffered from the man-in-the-middle and replay attack.In order to resolve this bug,a modified Diffie-Hellman key exchange protocol—AADH protocol was put forward.The AADH protocol has introduced some new technologies,such as key authentication,timestamps and random numbers which is the marker of communication.The analysis of the performance showed that due to the safe performance of Diffie-Hellman protocol,AADH protocol has high ability in fighting back the man-in-the-middle and replay attacks.
