Research On Mobile IP Technology And Security

The development and application of traditional Internet now can be seen anywhere in our daily life and work.Intemet can provide for us abundant value-added services,and also it holds tremendous information resources,thus greatly facilitating our convenient share and utilization of them.Though,Internet does have a big disadvantage of being unable to support host mobility,which leads to its inability to fulfill our daily-increasing mobility requirements. With the quick pacing of technology,the industry commonly holds a optimistic view on the coming integration between Internet and mobile communication.Mobile IP may positively exert its influence on this dramatic evolving process.In this dissertation the author firstly gives a brief report on development of Mobile IP and research on Mobile IP,then analyses Mobile IPv4 and Mobile IPv6 in detail,such as function-based constituents ,working process and control messages.in addition, we discuss the commons and difference between Mobile IPv4 and Mobile IPv6.Finally the thesis make a deep research on all kinds of invasion in Mobile IP network,then author employs the "Routing Mechanism Security"standpoint to provide a new security solution. extended Mobile IP protocol extends 3 control messages and introduces several new extensions, thus it can not only give strong authentication services but also achieves comparatively high protocol efficiency and good scalability.
