基于HFE公钥密码的单向壳核函数构造方案

针对构造公钥密码时, 出现函数单向性和陷门性矛盾的问题, 提出了一种新型的公钥密码体制单向壳核函数。根据HFE公钥密码的设计思想和结构特征, 给出了单向壳核函数的构造方案, 并研究了其能抵抗现有的主要攻击方法。与传统公钥密码体制相比, 单向壳核函数包容性更广, 变化更多, 安全性更高, 为人们提供了一种灵活性更强的公钥密码体制。

Construction Method of One-Way Shell Core Function Based on HFE Public Key Cryptography

Because of the contradiction between one way and trapdoor when we constructpublic key cryptography will turn up. a new type of public key cryptography with one way shell core function is proposed. According to the designing ideas and structural characteristics of HFE public key cryptography, the paperpresents a scheme of one-way shell core function and shows that the function can resist the present main attack methods. Comparing with the traditional public key cryptography, one way shell core function has the characteristics of wider inclusivity, more change and higher security. The function provides people with a public key cryptography of more flexibility.
