Securing Mobile IP Communications Using MOBIKE Protocol

Mobile IP is used to manage the mobility of the internet mobile users, and to keep their connectivity while they move from place to place. The security of mobile IP considering can be divided into two aspects, first in registration process, second, when connected parties exchange data with each other. In this article, after a brief study on the existing approaches used for securing mobile IP connections and after pointing to their problems, a new method will be introduced. This method is based on using IPsec security mechanism in conjunction with MOBIKE protocol. It will be pointed out that by using this proposed approach, the security of mobile IP connections will be achieved with respect to both two mentioned aspects. And also it is shown that most of the problems of existing approaches are eliminated in this method.
