摘　　要：Diffie-Hellman协议是用于正规场景中的基于离散对数的密钥交换算法,该算法要求通信双方建立长期可信任的伙伴关系。基于多态性Diffie-Hellman密钥交换协议,提出更加安全的多态性密钥交换协议设计方案,在交换协议中附加了通信双方的身份信息,可以由通信双方各自的伪随机序列产生器来共同设计多态性S-盒,这种多态性S-盒在非正规的场景中可以得到广泛应用。Diffie-Hellman key exchange algorithm, which is used in regular scenes based on the discrete logarithm problem, demands that both of two communication parties struck up a lively conversation long-term dependable fellowship. A much more secure polymorphic key exchange algorithm was proposed based on the Diffie-Hellman key exchange algo- rithra. The identity information of two parties can be appended to the agreement. Both communication parties use their PRNGs to finish the polymorphic virtual S-box together. The polymorphic S-box can become a broad agreement in irregular scenes.
