The design and research of improved JFKi protocol based on mobile IPv6

IPv6 as the trend of next generation Internet has increasingly implemented in the mobile Internet. The security of mobile IPv6 has become the key factor of restricting its development. The Internet Protocol Security (IPsec) protocol protects the exchange information between the Mobile Node (MN) and Home Agent (HA) through establishing the security association (SA). However, the IKEvl as the popular security protocol has the defects not to adapt the mobile Internet such as low efficiency and poor reliability. The Just Fast Keying (JFK) protocol is composed of JFKi and JFKr, and they are very similar in many respects. In this paper, we propose an improved mobile JFKi protocol based on IPv6. We simplify the complex of JFKi to improve the efficiency of establishing SA so that it reduces the load of mobile devices and improve feasibility of JFKi. We propose a model of mobility application based on mobile IPv6 to ensure JFKi adapt the mobility application. Through simulation, we prove correctness of the approach proposed by us.
