基于密码协议认证目标的协议分析方法的研究

为了克服现有的逻辑方法不适合分析电子商务协议的缺点,本文提出了一种基于协议认证目标的协议分析方法,该方法针对不同功能的协议,给出了他们要实现的目标:实体认证目标、密钥认证目标和伴随有密钥建立的实体认证目标。在文章的最后我们通过分析Diffie-Hellman密钥建立协议验证了该方法的正确性和易用性。

Study on One Way of Analysis Cryptographic Protocols Base on Protocols Authentication Goals

This paper introduces a kind of formal method which is based on protocols authentication goals to analyse cryptographic protocols. This method conquer the shortcoming of current formal methods that isn't fit to analyse electric commerce protocols, and it aim at the goals of all kinds of protocols functions. There are three goals of protocols: key authentication goalsentity authentication goals and entity authentication combined with key authentication goals.At the last of this paper we use Diffie-Hellman key agreement protocol as an example to verify this way is correct and easily to use.
