一个基于纠错码的密码系统

A CIPHER SYSTEM BASED ON ERROR CONTROL CODES

本文在概述了纠错与密码相结合的发展史后,针对传统的分组加密系统,提出了一个利用Reed-Solomon码来实现加密通讯的方案。并对实现时会遇到的一些问题,如加密钥和解密钥的建立,Reed-Solomon码的译码等进行了探讨。尤其是本文对Reed-Solomon码提出新的译码方法,具有实现器件看、易于硬件实现的特点。

After the introduction of error control codes and ciphers, we present a practical solution for cryptographic communication based on Reed-Solomon code, which is different from the traditional packet cipher system. Then we discuss some problem, such as creation of cryptographic key and decryptographic key, the decoding of Reed-Solomon code, which may be encountod on implementation. The decoding algorithm of Reed-Solomon code can be easily implemented by hardware.
