Research On Application Of SSL Security Agent In CDN System

Content Delivery Network is a new network structure that was added to the layer of existing Internet,Through the approach that content of site were posted to the closest to the user's network "edge" , To improve the overall performance of the network.For a complete CDN network, Security is must requirements. in this paper, just to data transmission security problems in CDN system, SSL security agent based-on is designed to protect the safety of communications services.The main research work In this paper as follow:1.Describe contents of information security which related to the SSL protocol, study SSL protocol in-depth, Analysis of the security issues about SSL protocol in the network environment, and performance problems that exist in CDN system, and some improve has been done.2.Based on understanding the mode of CDN system deeply , we focus on analysing the security issues of CDN services in the network, And for problems, A security solutions based on SSL agent has been designed.3.Because of client and server has a different services performance requirements, A design was Proposed to the client and server-side SSL security agent. By focusing on server-side because of large access, Easy cause access bottleneck, Designed a SSL security agent model specially, To parallel processing of requests for information, So as to effectively reduce the burden of server-side.4.The system model has been designed, A detailed analysis to model's various components has done. Finally, analyse system performance and security. The system can be very good to improve the network quality of service by analysing.
