浅谈PKC体制及一种重要算法的实现

The Public Key Cryptosystem and Implement of an Important Algorithm

"公开密钥密码体制(PKC)"是现代密码学的最重要的发明和进展,RSA算法是目前最重要的公开密钥密码算法之一。首先简要介绍了密码学及PKC体制,然后重点对RSA算法的基本原理、实现等进行阐述。通过对RSA算法的特点以及目前的密码技术发展情况的分析,认为RSA算法在将来仍旧是应用最广泛的加密解密算法之一。

＂Public Key Cryptosystem（PKC）＂is the most important discovery and development of the modern cryptography.At present,RSA is one of the most important PKC algorithms.In this paper,the cryptography and PKC are described first,and then the basic principle and the realization of RSA are given in detail.In terms of the analysis of RSA and current situation in cryptography,RSA will remain the position that it is one of the encryption algorithms widely used in future.
