The Development And Security Assessment Of Digital Signature System For E-commerce

With the continuous development of computer science and technology, information technology in all areas of society more widely, with the attendant security problems have become increasingly prominent. The development and progress of cryptography provides a basis for digital signature technology research digital signature technology is data transmission over the Internet was a great application, it can add the document electronic document owner’s signature information transmitted via the network to reach the recipient, according to the signature information to authenticate the sender, electronic document in order to achieve the security of information transmission, to effectively prevent the communication entity and the communication party to forge the identity of the communication problem of denial of fact.With the increasing development of information technology, calendars, e-commerce becomes a very important trade instruments. The openness of the Internet network, anyone can easily seamless access to the Internet, network data sharing, so that there is a wide variety of e-commerce security risks, e-commerce data transmission process of information security issues become a very prominent, an urgent need to solve the problem. To address these security issues, digital signature technology is more widely used in the field of e-commerce, e-commerce transactions can effectively solve the identity and information activities of forgery, tampering illegal transaction information, the transaction is not a party to the transaction admitting or denying other issues.This paper introduces the basic theory of digital signature technology, the application of e-commerce activities and security requirements, based on the analysis of the classical digital signature algorithms, such as DSA algorithm,RSA algorithm,and digital signature technology in the application of e-commerce activities carried out research and analysis. Using VC language development to achieve a digital signature system for e-commerce, and the security of the system is analyzed. Aiming at the security hidden danger existing in the system of digital signature, the improving measures are put forward.
