基于F度量,构造了最大F距离码,提出了基于最大F距离码的新McEliece公钥密码系统.合法接收者通过引入一个随机矩阵X作为附加私钥,并把X加入到原始公钥中,从而产生了一个新的公钥,使该密码系统能够有效抗击敌手通过已知的公钥获得私钥的攻击.同时F度量的引入,提高了攻击密钥体积较小的公钥密码系统的复杂度和难度.通过对现有可行攻击方法的分析,说明了基于最大F距离码的新McEliece公钥密码系统是安全可行的.

In terms of F-metric,the maximum F-distance code was constructed,a new modification of the McEliece public key cryptosystem based on maximum F-distance codes was proposed.The legal party chooses a random matrix as an extra secret key and adds it to the original public key to produce a new modified public key.It makes such cryptosystem effective for resisting the attack based on getting private keys from known public keys.Moreover,using F-metric increases the complexity of the system,making it harder to attack allowing for smaller key sizes.Attacks on such a system were also investigated It is shown that the McEliece public key cryptosystem based on maximum F-distance codes is security and feasibility.
