密码学控选逻辑控制序列与输出序列互信息为零的一个充分条件

One condition which satisfies that the mutual information is zero between control and output sequences of the control-choice cryptographic logic

本文在几种常见的密码学控选逻辑技术的基础上,给出了一般密码学控选逻辑的概率模型,得到了密码学控选逻辑控制序列与输出序列互信息为零的一个充分条件。本文结果对密码编码学中序列密码的编码具有一定的指导意义。

From several types of the control-choice cryptographic logic ,we get it's general probability model. In this paper, one condition is gained which satisfies that the mutual information is zero between control and output sequences of the control-choice cryptographic logic.
