Reserch On IPsec Based Network Security Scheme For Mobile IP

Because the information technology flies to soon develop,pass stationary wireways progress the mode of the network communication incapability in the stationary place have already satisfied need of people,people hope dynasty can on the first be like to use a cellular phone so,carry out to the network in the movement of without a break access,enjoy a network to provide to one of our service in the movement,still need to guarantee to move to get to the Internet in the meantime of stability.This text wants to speak of the movement IP technique is exactly for carrying out this object but design.This thesis expectancies moves from the introduction IP technique and it of the priniple machining commence,and move IP characteristic and solid,then give move the IP be hard the large scale apply of reason;Amalgamation to firewall concept progress definition,then lead into movement the IP cross the question of firewall,and introduce the system that the reverse direction tunnel crosses a firewall,and existence movement safe question for IP to cross.Design the association scheme of IPSEC technique and movement IP technique in the meantime,technique and firewall technique of the wedge bonding IPSEC cross to design for the implementation a safety of platen,provide a safe guarantee for the consumer.This paper analyzes a kind of DCS network system based on IPsec,it is a kind of suitable for mobile IP environment certification mode-mixing system authentication mode,it is only in the first authentication using public key encryption,the certification are available through the shared key.This method can not only fully reflects the public key authentication based on the advantages of easy to deploy,and on the premise of ensuring function to make use of the shared key to improve efficiency,this way from many aspects.and realize the function of safety performance than before the network structure has been greatly improved,in particular this approach is tailored for mobile IP,very suitable for large-scale deployment of mobile IP application future.Will become the next generation movement the nucleus of the network according to the IP wireless network.In the whole IP wireless network,the movement is to the multi-media application have full important action.Movement IP is the IP adapt each period need of a typical model example.The movement IP make just for the computer of stand type design of the network standard adapted then the demand of the hold type movement equipment,and will be far in the anti future contented more the small more lightly moves the demand of equipment.Because these networks need to be receive more adequately contented,the movement nodal point will also acquire further application.Can discover movement IP and the movement IPv6 is the key technique that the wireless Internet carries out movement.Will be a future beehive according to the IP wireless network the nucleus of the network.But currently how run more and safely carry out movement still keep being the question which needs further research.
