摘要
Diffie-Hellman(D-H)算法可以实现密码系统的密钥交换,其安全性依赖于计算离散对数的难度,并且Diffie-Hellman密钥交换协议能够提供前向保密性。文中通过分析Diffie-Hellman密钥交换协议,给出了一个可以应用于任何非对称密码体制的具有前向保密的密码协议。
Diffie - Hellman(D - H) algorithm can exchange the key in a crypto system,the security of which is based on the discrete algorithm. And Diffie - Hellman key - exchange protocol can provide a crypto system with the forward secrecy. Analyze Diffie - Hellman key - exchange protocol, and present a crypto graphical protocol with forward secrecy which can be applied to any asymmetric erypto systems.
