Mobile IPv6 (MIPv6) Route Optimization Security Design Protocol
Abstract—Abstract Unlike Mobile IPv4, where mobile node communicates with its peer through a longer path, via Home Agent, in Mobile IPv6 a mobile node directly communicates with its peers even though it moves to the new location and changes its IP address, this mechanism is called Route Optimization. In Route Optimization, the mobile node sends the binding message to its peer node, the message contains the new address of the mobile node, called as Care of Address, which confirms that the mobile node is infect moved to the new location from its Home Network. After receiving the binding message, the peer node sends all packets which are destined to the Mobile’s Home Address to the Care of Address. But there are many security risks involved, when a malicious node might be able to establish a connection with the mobile node by sending the false binding messages. By doing so malicious node can divert the traffic, can launch the DOS Attacks and can also Replay the authenticated messages, etc. So considering theses security issues, we have proposed a secure protocol which prevents the attacker to establish false connections and assures the secrecy and integrity of the mobile node and its peers.
