| 摘 要： | 文章提出一种新的基于离散对数的单/多密钥交换协议.本协议具有身份认证功能,可以避免DiffieHellman协议中存在的漏洞--中间人攻击,而且它不使用散列函数,即可进行单密钥交换又可进行多密钥交换.与基于离散对数签名方案的变体的那一类密钥交换协议[7,8]相比,本协议具有一定程度的隐私性.

| Abstract: | A new key/keys exchange protocol based on the discrete logarithms problem is proposed in this paper. Our protocol has authentication performance, so it is free of the man-in-the-middle attack, which exists in the Diffie-Hellman protocol. Our protocol has not hash function and can exchange one key or some keys. Compared with those based on modifying specific, discrete-logarithms-like signature schemes, it has somewhat privacy for the communicating parts. |
