Design And Implement Of The Web Information Security Channel Based On SSL Protocol

With the development of computer network especially the Internet, the security of network receives more and more attention. The Internet is based on TCP/IP protocols, but TCP/IP protocols can't guarantee the security. To solve these problems, various solutions have been brought up. The secure transport of data has become the emphasis of network environment and one of important factors of network development. SSL protocol is one of the most famous secure protocols.SSL protocol belongs to the session layer, and plays an important role in the Internet. Presently, many of the famous commercial products of browsers and web servers support SSL. SSL has become the most prevailing WWW secure protocol.Many develops have released secure products based on SSL, but, most of the secure protocols are subject to the limitation of export regulations. Most of them adopt weak cryptography algorithms (with key of 56bit downwards) and its source code isn't published. To satisfy the demands of the e-governmental affair, e-commerce and other affairs, we developed a SSL proxy on client side.This thesis consists of two parts. The first one analyses SSL based on confidentiality, integrity and authentication, SSL handshake protocol are described in detail. Provides some measures against current attacks on SSL protocol. The second one presents the design and implement of SSL secure proxy on client side. In the end, the author points out the work should be improved in the future.
