摘　　要：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,通过引入单向壳核函数新型公钥密码体制,根据可编程逻辑器件PLD的设计思想和结构特征,给出一种单向壳核函数的构造方法,其安全性等同于一次一密.与传统公钥密码体制相比,单向壳核函数具有更广的包容性和更高的安全性,是一种灵活性更强的公钥密码体制.In view of the contradiction between one way and trapdoor occured on constructing public key cryptography,the author introduced a new type of public key cryptography that is one-way shell core function.According to the designing ideas and structural characteristics of programmable logic device（PLD）,the paper presents a scheme of one-way shell core function and shows that its security is equal to that of one-time pad.Compared 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.
