信息战中的信息加密技术

Information Encryption Technology in Information Warfare

介绍了信息战的背景；描述了信息战的概念；概述了在信息战中，进攻方和防守方为保护信息使用的加密技术，并较全面的提供了数据加密标准、分组迭代快速数据加密算法、标准分组密码算法、非专用分组密码算法、密钥可变分组密码算法等２０多种加密算法，这些算法反映了近年来加密技术的发展，并有可能为加密技术的成功实施提供一些新的思路。

In this paper, the concept and background of information Warfare are introduced. The encryption techniques for protecting information both for offensive and defensive are described. More than twenty block cipher algorihtms are discussed. Especially emphases are given to those algorithms representing the current development of encryption technology in recent years, which might provide some new ideas to the techniques.
