房产证信息数字签名的实现

摘 要
随着数字技术和安全技术的飞速发展，证件的防伪技术已成为信息安全领域亟待解决的问题。在信息安全上数字签名可以起到身份认证、核准数据完整性的作用。目前关于数字签名的研究主要集中基于公钥密码体制的数字签名。
现在公钥密码体制已成为确保信息安全性的关键技术。RSA公钥密码体制是一种被广泛使用的公钥密码体制。本论文详述了RSA算法，SHA-1哈希散列函数。将RSA公钥加密体制与SHA哈希算法结合来实现了一个简单的房产证信息数字签名防伪仿真软件，本论文详细讨论了RSA加密算法的实现过程，通过对系统的测试说明在房产证防伪鉴别中,数字签名是可以用于证件真伪鉴别。

Realization of Digital Signature
for Information of Certificate of House Property
Abstract
With rapid growth of digital technique and safety technology，Identification document protection technology has become a desired issue in the security of information. Digital signature technology in information security has effect on authentication, data integrity. Currently research of Digital signature technology mainly is the digital signature based on public key systems.
Public-key cryptosystem has been a crucial problem of information security. RSA public-key cryptosystem is one of the widely used public-key cryptosystems. This thesis is concerned with the algorithms of RSA and hash function (SHA). Then to combine the RSA digital signature algorithm with hash function (SHA), a simulation soft anti-counterfeiting system for certificate of land and house property is given. In this thesis, the RSA encryption algorithm is discussed in details. A digital signature for authentication is used in Certificate Anti-Counterfeit

Key words: RSA; digital signature; hash function (SHA); Certificate Anti-Counterfeit; Authentication
