The Research And Design Of Network Security System Based On SSL Protocol

With the rapid development of computer technology, information network has become an important guarantee for social development. National information network involving government, military, cultural and educational fields. Are one of many important government macro-control policy-making, business and economic information, bank funds transfer, stock securities, energy resource data, scientific data and other sensitive information, and even state secrets. Will inevitably attract all kinds of man-made attacks (such as information leakage, information theft, data tampering, computer viruses, etc.), so that network systems are faced with a serious threat, and become one of serious social problems.This article is through practical work on cryptography, information security and understanding of the SSL protocol and study design based on a solution to the above-mentioned problem of network security systems. Mainly based on the SSL protocol to design a network security system, using CA certificate of identification technology, the introduction of the core security module implementation selection mechanism, according to the need to protect the information security level and the project budget, you can choose to use feature-rich OpenSSL open-source code base, or selection of information security equipment vendors to provide network security devices achieve security module, in the public network dedicated channel set up encryption communication channel, the channel implementation in unsafe safe transmission of data, thus ensuring that sensitive information transmitted on the network when the confidentiality and integrity sexual.This article is divided into six chapters. Chapter I Introduction and summarized in this article discusses research background, both at home and abroad and major research studies. Chapter for cryptography-related technologies, papers are password knowledge base. Chapter III of the SSL protocol from the composition of the structure and safety areas such as analysis and research work. Chapter IV of the agreement based on the SSL network security system design, primarily from the system design principles, design thought, the system divided into functional modules, system performance analysis and the key technology areas. Chapter V of the agreement based on the SSL network security system implementation, from the development environment, implementation modalities, SSL protocol version and cipher selection, etc. to carry out the work flow. Finally, conclusions and future work.
