摘要
论文首先简要介绍了M公钥密码体制,然后重点讨论了基于RS码,利用广义置换矩阵改进的M公钥密码体制,最后对这种改进的M公钥密码体制的安全性进行了分析,证明它的性能和安全性都优于M公钥密码体制。
This paper first brieftly introduces M-public-key cryptosystem, then discusses an improved M-public-key cryptosystem, which is based on RS codes and makes use of the generalized permutation matrix, and finally analyses the security of the improved cryptosystem.It has proved that the performance and security of the improved cryptosystem are better than M-public-key cryptosystem based on Goppa code.
