房產(chǎn)證信息數(shù)字簽名的實現(xiàn)

摘 要
隨著數(shù)字技術(shù)和安全技術(shù)的飛速發(fā)展，證件的防偽技術(shù)已成為信息安全領(lǐng)域亟待解決的問題。在信息安全上數(shù)字簽名可以起到身份認證、核準數(shù)據(jù)完整性的作用。目前關(guān)于數(shù)字簽名的研究主要集中基于公鑰密碼體制的數(shù)字簽名。
現(xiàn)在公鑰密碼體制已成為確保信息安全性的關(guān)鍵技術(shù)。RSA公鑰密碼體制是一種被廣泛使用的公鑰密碼體制。本論文詳述了RSA算法，SHA-1哈希散列函數(shù)。將RSA公鑰加密體制與SHA哈希算法結(jié)合來實現(xiàn)了一個簡單的房產(chǎn)證信息數(shù)字簽名防偽仿真軟件，本論文詳細討論了RSA加密算法的實現(xiàn)過程，通過對系統(tǒng)的測試說明在房產(chǎn)證防偽鑒別中,數(shù)字簽名是可以用于證件真?zhèn)舞b別。

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
