摘要
纠错码与密码的结合是代数编码理论和密码学发展的必然产物。介绍了单钥体制的一般构造及分析单钥体制安全性的3种攻击方法,讨论了两种基于纠错码理论的单钥分组密码体制,建立了一种同时具有检错和对消息认证、保密功能的新的单钥体制。该体制不仅保留了Rao-Nam体制的优点,而且比Rao-Nam体制有更多的优越性和更强的实用性。
The union of error correcting code and cryptosystem is the inevitable product ofthe development ofthe algebraic coding theory and the cryptology. On the basis of a presentation of the common configuration of single key cryptosystem and an analysis of three kinds of potential attacks on its security, two single key grouping cryptosystems based on error-correcting code theories are explored, thus a new kind of single key cryptosystem is established, which simultaneously detects errors and confirms and safeguards new information. This new system not only retains the merits of Rao-Nam system but also shows greater superiority and practicability.
