The Design And Implementation Of An Online Shopping System Based On PKI

The rapid developments of the Internet, as well as the continuing progress of the computer network and communication technology has made it come true that our society has come into the information age. Thus, it is the case that we find it difficult to separate our lives from the network in all aspects, and people have gradually accepted the online trading activities, that is electronic commerce. Electronic commerce has become the inevitable trend of the development of global business. And as we all know everything has its advantage and disadvantage, so does the network, it brings us convenience at the same time it also brings many unsafe factors, In which the biggest problem the present electronic commerce system is facing is the security, so how to protect the security of electronic commerce system is a problem worthy of study. At present in the electronic commerce system such measures as the encryption, digital signature mechanisms, access control mechanisms, digital integrity mechanism, digital certificate mechanism are often used to guarantee the safety in the process of electronic transactions.Aiming at the existing security problems of the on-line shopping system, this paper introduces the design of an online shopping system, which is based on PKI. Firstly, this paper analyses the current e-commerce platform security threats, studies the current measures international security issues taken for e-commerce security so as to put forward the e-commerce system security framework, Based on OpenSSL platform, we can make full use of its advantages of the open source code, the support for most mainstream cryptographic algorithm, the support a variety of system platform and so on, we put the digital certificate and SSL security protocol into the use of the online shopping system, and obtain the realization of secure online shopping system, which is based on the PKI.
