RSA密码体制及数字签名技术的研究

随着计算机网络和信息技术的发展，信息安全在社会各领域发挥着越来越重要的作用，其中安全与保密已成为信息安全技术的一个核心内容。现代密码学的主要研究领域之一就是数字签名，它在身份识别、认证、数据完整性等方面具有其它技术不能取代的作用，在电子商务、电子政务及数据库安全等领域有着极突出的作用。该文首先介绍了数字签名的研究背景原理，接着探讨了基于RSA算法的数字签名系统及应用。

Research on RSA Cryptography and Digital Signature Technology

With the development of computer network and information technology, information security plays a more and more important role in each field of society, the security and privacy has become a core of information security technology. One of the main research fields of modern cryptography is the digital signature, it has the other technology can not replace the role in the identification, authentication, data integrity, etc, it has a very important role in e-commerce, e-government and database security fields. This paper first introduces the research background of digital signature principle, and then discusses the digital signature system based on the RSA algorithm and its application.
