基于RSA的安全应用及漏洞分析

Secure Applications and Leak Analysis of RSA System

目前 ,公钥密码系统在网络安全中的应用越来越广泛 ,尤其在典型代表RSA系统得到大量使用。将系统地介绍和阐述RSA公钥密码系统的基本原理 ,介绍目前在计算机网络安全领域的几类基本应用 ,并针对其设置和应用的漏洞分析 ,提出安全应用RSA的参数选取和避免攻击的解决办法 ,最后还探讨了RSA的发展趋势。

At present,application of public key cryptographic systems in the field of computer network security becomes wider and wider。Specially, RSA,which is the typical representation, has been widely used.The basic principle of the RSA public key cryptographic system will be introduced and clarified systematically in this paper. At the same time, some kinds of basic applications in the field of computer network security will be introduced also.How to select the RSA system parameters and how to avoid attack will be put forward through leak analysis of its settings and application.Finally, the developing trend of the RSA is discussed.
