RSA数字签名技术与安全性研究

A Study of the Technology and Safety of the RSA Digital Signature

在网络通信中,要采用各种密码体制实现信息的安全、可靠、完整等特性,其中使用最广泛的是公钥密码体制RSA。首先介绍了数字签名的概念和功能,然后对RSA密码体制算法进行研究,分析了用RSA进行数字签名的过程,最后对RSA在数字签名过程中可能受到的各种安全威胁进行分析,并通过总结得出在数据加密及数字签名领域中RSA起着非常重要的作用。

All kinds of password systems are used in network communication to make information secure, reliable,and intact,and one of the most widely used systems is the RSA public key cryptosystems.This paper firstly introduces the concept and the function of the digital signature.It then studies the RSA cryp-tosystem algorithm and analyzes the process of the RSA digital signature.Finally it discusses all kinds of RSA security threats in the process of digital signature,and concludes that the RSA cryptosystem plays a very important role in the field of data encryption and digital signature.
