【Abstract】 Now the network security service is provided by the security gateway.The most widely used protocol is Internet Key Exchange protocol (IKE).The initial IKE standards work well for peers with fixed IP address.But with the development of the network,especially after the mobile network is introduced,the methods of accession have been multiplied,which has aroused a problem that the IP address of the computer is no longer fixed.How to provide the security service in such a kind of network is a current focus.In this paper,how to combine the IKE with the Authentication Methods is introduced.The advantages and disadvantages of the ways are discussed.The situations in which such ways could work best are analyzed. In the end a conclusion is drawn that in the network in which the IP address is not fixed,the performance of the IKE could be promoted.更多还原
