Based Ipsec Network Security Technology Research And Applications

The Research and Application of Security Technologyof Network based on IPSEC[ABSTRACT] IPSEC is a new choice to deal with the increasing requirement of security of Internet. It is honored as the new generation of standard of Network Security. Having described varieties of security technologies of network and their use and position in dealing with network security, the paper emphasizes on security importance of packet when it is traveling. Comparing with very kind of scheme to solve the problem, the paper gives prominence to IPSEC and describes its characteristic and prominence in solving the problem. The paper describes the key technology applied to IPSEC桝lgorithm, Key Management, and how they connect with and work on IPSEC in detail. Subsequently, the paper emphasizes on analyzing the framework, the structure of packets and the process to deal with IPSEC packets. Because of the base position of Key桬xchanging Protocol in IPSEC, the paper describes the theory and packet structure of its Key-Exchanging Protocol桰KE in detail. In the last of the paper, two examples are described how to apply with IPSEC, one of which applies PGPNET to transfer packet in secure way in Local Area Network, the other of which builds VPN based on IPSEC in Campus Network, which can simulate the situation of Internet.
