Security Technology In The Electronic Commerce

Electronic commerce is one kind of new commercial operation pattern under the Internet opening environment and the network technology application brand-new development direction. Electronic commerce has changed the traditional trade form, the enterprise production, the management, and will lead to a new revolution in such fields as economy, society and culture. As a result of network environment openness, there are also many problems in the electronic commerce development at present.(1) Security agreement question: The fact that there isn't the standard to the security agreement has restricted the international commercial activity relatively.(2) Safety control question: generally speaking, the very big hidden danger in the safety control aspect makes it difficult to resist hacker's attack.At present, the security technology is the key factor in guaranteeing the electronic commerce health and is a matter of concern. Although the Internet's open style exchange of information causes it to have the vulnerability in the security aspect, the present network on each level has drawn up the security agreement and the corresponding security technology to guarantee the electronic commerce's security.This article mainly studies one of main kinds of the on-line payment agreement: Security electron transaction SET (Secure Electronic Transaction) agreement:The SET agreement can guarantee the secure payment through the opening network standard, it has defined a complete electronic transaction flow, has solved the electronic transaction between all quarters of the complex trust relations and the safe connection, has guaranteed the electronic transaction the infonnation authenticity, the secrecy, has guarded against denies the nature of the information. The protocol uses such technologies as symmetrical key encryption, public key encryption, Hasche algorithm, digital signature as well as public key authorization mechanism and so on.The paper first obtains from the electronic commerce platform, analyzes this kind of platform the overall function frame and the related core technology. Then according to the MVC development pattern and Java language platform irrelativity, as well as opens source project Struts completely based on MVC pattern Apache Jakarta, it explains the electronic commerce platform development necessity andsuperiority. Moreover, the author studies the private key encryption and its limitation public key encryption system and the digital signature algorithm in this foundation (DSA), realizing a this digital signature algorithm with Java language and using digital signature technology to a designed electronic commerce platform.
