TOKEN BASED SECURITY IN MIPV6, HMIPV6 AND IN DYNAMIC MAP MANA GEMENT HMIPV6

Mobile Internet Protocol (MIP) is a standard protocol defined by Internet Engineering Task Force (IETF) that allows mobile devices to maintain a permanent IP address irrespective of their roaming between networks. In this paper we present the working and issues related with various MIP versions and their solutions. In addition, we have proposed a token based solution for authenticating the Mobile Node reaching any foreign network and securing the Binding Update messages send by MN to Home Agent (HA) and Correspondent Node (CN) when it moves from one network to another network.
