The Technology Analysis Of SSL Protocol And Its Applied Research In Electronic Commerce

The e-commerce based on Internet has become the new focus because of the rapid development of Internet. The e-commerce has brought a revolution to traditional trade way. The e-commerce not only makes the market globalization but also reduced operation costs of the trade company.Net security is basis of implementing e-commerce, safe and credible net protocol is one of key technologies that insure e-commerce safely implementing. However, most of the electronic business secure protocols are subject to the limitation of export regulations. For example, only 40 bits or 56 bits of RC4 algorithm and 512 bits of RSA algorithm are permitted to export, and its source code isn't published. It isn't satisfied with the secure requirement of the electronic business in our country. It's very significant to design or rebuild the secure transport protocol with our own cryptogram algorithm based on the research of its idea and principle.In this article, the fondamental knowledge of cryptography are introduced first. The author introduces the message digest algorithm, digital signature and X.509 certificate which are the foundations of authentication in public key systems. Next, SSL protocol is analyzed. The security of SSL based on confidentiality, integrity and authentication is analyzed in detail. Primary implemental ways and its questions for SSL protocol to carry out on confidentiality, integrity and authentication are indicated. Then, design scheme and implemental method of a secure electronic commerce system based on SSL are proposed. Security gateway that based on SSL procotol in the server and secureity agent that based on SSL procotol in the client are designed in detail. In the end, the author points out the work should be improved in the future.
