扩散码及其密码学用途

Diffusion Codes and Their Cryptographic Utilities

本文提出了单比特和多比特扩散码以及用它们构造认证码和分组密码的方法。这些密码学函数可以用快速且类型单纯的操作指令来实现，迭代轮数少，且有好的安全性，用软件硬件均容易实现。

Single bit and multiple bits diffusion code and the method of constructing authentication code and block cipher used with them is suggested in this paper.These cryptographic functions can be constructed by fast and simple operating instructions with fewer iterative rounds and with fine security.They are easily implemented with software or hardware.
