Analyse Improvement And Test Of Secure Protocols In Data Transmission Process

Secure techniques in communications are key problems in the information society, which have near connections to the security and stability of country and society. The SSL protocol developed by Netscape Communications is a famous secure protocol in data transmission process, which is widely applicable in communication security. The paper introduced secure data transmission technique and relevant background knowledge, then the author gave an analyse of SSL protocol. The author pointed out the function of the protocol and gave some improvement schemes, expatiated relevant knowledge in the design of secure data transmission. Advanced a practical scheme in the design and test of secure gateway and correlated products.The theoretical contributions of this paper are that the author analyzes the bottom layer of the protocol, pointed out the elliptical curve and secondary encryption in RSA based on common used secure protocols. Which is valuable to those whose research field is security and the industrial field especially to those who want to produce our own property right products. The author offered relevant knowledge in the selection of RTOS according the practical experience. At last the author raised requirements of secure function and protection, which may offer theoretical guidance and reference to research and test of such secure products.The practical contributions of this paper are that the author configured the SSL protocol and improved it by elliptical curve and secondary encryption. Realized the secure server and browser based on SSL protocol in the kernel of the operate system. Entirely analyzed the secure protocols in www especially to SSL protocol. Finished the protocol coherence test etc. It was proved to be viable through the practical testing process.
