摘要
本文基于对称密码体制和公钥密码体制的特点,提出了密码体制的一个统一的数学框架,在该框架下,可把对称密码体制和公钥密码体制归结为该框架下的一种特殊情形。在此基础上我们构造出快速高效的公钥密码算法,并对该算法进行了安全性和效率分析。
In this paper,a unitary mathematics frame of cryptosystems is presented based on the private key and public-key cryptosystems.Under this frame,the private key cryptosystems and the public-key cryptosystems are reduced to its a particular form.And from which the fast and efficient public-key cryptosystems are constructed,and their security and efficiency are analysed.
