对称密码的流密码

The Stream Cipher of Symmetrical Ciphers

讨论一种可能被广泛推广的对称流密码.介绍流密码的整体结构,设计流密码需要考虑的主要因素.探讨了一种具体的对称流密码RC4算法及RC4算法的建立过程和它的强度.

This paper is to discuss one of the stream ciphers in symmetrical cipher probably to be extensively spread.First,it is not only to introduce the whole structure of the stream cipher but also to design the stream cipher concerning the major factors.Then,the paper studies the algorithm of the stream cipher.
