摘要
网络系统最主要的安全技术是数据加密,而RSA算法是密钥系统最安全的一种体制,其算法的安全性基于数论中大素数分解的困难性。该文首先介绍RSA公开密钥加密算法数学原理,并讨论RSA算法固有缺陷,最后分析RSA算法的安全性。
The most main security technology of network system is data encryption, but P.SA algorithm is the safest system of key systems. its security is based on the difficultly of dividing big prime number. This paper introduces the mathematic principle of P.SA public key encryption algorithm, discusses the inherent limitation, and then analyses the security of RSA.
