Research On The Security Technology Of E-Commerce

Electronic commerce is the commercial activity conducted by computer network, e-commerce cost give a significant advantage in the future, however, as e-commerce activities are carried out based on the open Internet, security has become a key factor in the development of e-commerce to address the safety issues as a prerequisite for the e-commerce. Further development.This paper analyzed e-commerce and security needs, and summarized the current e-commerce security technology used applicationsThen systematically studied e-commerce security technology and encryption technology, therefore achieve the principle work conducted in-depth discussion on the RSA algorithm parameter selection process in different ways and under different attacks, Carried out a detailed security analysis and detailed description; Meanwhile, study both SET and SSL security protocols, and detailed analysis the working mechanism for the two protocols, workflow, providing security services and the shortcomings of the distinction between them in general.Finally, with Java programming language, MyEclipse as a development tool, the paper design and implement a RSA based encryption and signature system, system by the client and server side of two parts, the test shows that the system can accomplish the encryption files in multiple formats And the digital signature process can be used to implement e-commerce data confidentiality, integrity, authenticity and non-repudiation.
