产生“一次一密”会话密钥的抗重放攻击鉴别协议

Identification Protocols Secure Against Reset Attacks and Generating One-time Session Keys

文章在抗重放攻击的身份认证协议的基础上,提出了一种新的产生会话密钥的协议,在身份认证后的协议执行的每一步,利用DIFFIE HELLMAN算法产生的密钥作为移位寄存器的初态,由移位寄存器产生适当长度的密钥流作为会话密钥,且此密钥只使用一次,达到了或接近了"一次一密"的效果,具有较高的安全性。

This paper presented a new method of generating the key used only once based on a identification protocols secure against reset attacks. In every step,we use DIFFIEHELLMAN algorithm to generates the first state of FSR. Then the FSR generates onetime key. The protocol is more security that conventional protocols in generating session key.
