一种密钥流的生成方法及其攻击分析

The Research of Key Stream Produced by New Method and its Attack Analysis

本文分析了目前密钥流的实现方法,提出一种把克罗内克加矩阵扩大法运用于序列密码的密钥流的生成中去的方法,并对序列密码种采用新密钥流加密方法进行简要的攻击分析,结果表明,该种方法是有效的,生成的序列能通过随机性检测。

This paper puts forward a new method that can get sequence cipher with Kronecker plus Matrix-extended in Encrypt System by the analyses of realizations for key stream. And does some attack analysis to the encrypt sequence with the new encrypt method. The results show that this method is effective and the new sequence can pass the random test.
