摘要
引入奇、偶扩展明文的概念 ,给出基于RSA的随机加密算法 ;给出加密安全空间、安全可靠度等定义 ,得出了保密安全特性的一些基本结论 .
A random encryption algorithm based on RSA is developed by use of the concept of odd and even plaintext expansion. The definitions of encryption security space and security dependability are given to describe the security indexes for the encryption algorithm, and some basic conclusions on cipher security are drawn.
