McEliece公钥体制的修正

Modification of McEliece's Public-key Cryptosystem

本文针对Ｋｏｒｚｈｉｋ和Ｔｕｒｋｉｎ对ＭｃＥｌｉｅｃｅ公钥密码体制的攻击，对ＭｃＥｌｉｅｃｅ密码体制提了一种修正方案，分析了它的安全性和其它性能，论证了这些修正方案不仅能有效地抗击Ｋｏｒｚｈｉｋ和Ｔｕｒｋｉｎ提出的攻击，而且也能很好地抗击其它已知的攻击方法。

In this paper,we propose a method to modify McEliece's public-key cryptosystem which can resist the Korzhik and Turkin's attack algorithm. In addition,the security and performances of our cryptosystem are analysed,and it is shown that our cryptosystem is secure against the attack proposed by Korzhik and Turkin,as well as other known attacking methods.
