Realization of Digital Signature for Information of Certificate of House Property
Abstract : With rapid growth of digital technology and safety technology, Identification document protection technology has become a desired issue in the security of information. In information security, As an important safety technology, Digital signature has played an extremely important role in ensuring integrity, confidentiality, non-repudiation of data. 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 article details the RSA algorithm, and SHA hash algorithm. Then to combine the RSA digital signature algorithm with hash function, a simulation system for certificate of land and house property is given, description of the digital signature can be used to identify the authenticity of the documents.
Key words: RSA; digital signature; Certificate Anti-counterfeit; Authentication
