摘要
为了能够真正在2个通信参与者Alice和Bob之间协商1个密钥,就必须确保他们在协议运行过程中收到的信息的确是来自真实的对方。本文给出了1种基于随机字符串的认证密钥交换协议以对Diffie-Hellman密钥交换协议进行改进。这对于电子商务等很多网络应用而言是至关重要的。本文也给出了这种协议的安全性分析,并描述了基于JAVA的实现。
In order to agree on a key which is exclusively shared between Alice and Bob, these principals must make sure that the messages they receive in a protocol run are indeed from the intended principals. In this paper we propose a protocol to modify the Diffie-Hellman key exchange. This protocol can provide authentication based on random strings. This is critical for many network applications such as ebusiness etc. Security analysis of this modified protocol given to its implementation based on JAVA is also presented.
