综合型密码系统与网络通信安全性

SYNTHETIC CRYPTOSYSTEM AND COMPUTER NETWORK SECURITY

网络信息处理安全性,主要归结于网络通信安全性,而密码技术提供了一种确保通信安全性的可行办法,但现有的对称型密码系统在网络环境下不能进行有效的密钥分发,而非对称密码系统虽较好地解决了网络环境下密钥分发问题,但其加密解密算法效率非常之低(至今尚未提出高效率的非对称型密码算法),因之,还不具有高的实用价植。本文试图解决这个问题,提出了综合型密码系统概念。文中所论述的综合型密码系统具有密钥分发简单有效且加密解密算法执行效率高的特点,在网络环境下有较高的实用价值。

In this paper, a new type of cryptosystem -synthetic cryptosystem is pro-posed and designed. Both of the old types of cryptosystem -symmetric and asymmetriccryptosystems have little value of practical application under network environment. Thespeed of asymmetric cryptosystems encryption and decryption is rather low. Symmetriccryptosystem can not solve the key distribution problem over the network. This paper putsforward the ways to solve this currently open problem.
