Qin Shen · Journal of Beijing Broadcasting Institute · 2002
With the Rapid development of IP network, the potential danger which is produced by the illegal attack prove to bring great losses. The IP Security Protocol will develop mechanisms to protect client protocols of IP. A security protocol in the network layer will be developed to provide cryptographic security services that will flexibly support IPv4 and IPv6. This paper explicates the importance of using IPsec, analyses its system structure, explains the work principle of IPsec; Also it gives the application of virtual private network which is on the basis of IPsec, systematically analyses the whole frame of virtual private network and some of its specialty.
