A METHOD FOR BINDING UPDATE IN THE MOBILE IPV6 AND A MOBILE IPV6 COMMUNICATION SYSTEM

摘要

A method for binding update in the mobile IPv6 is provided. After a binding management key is obtained in a return routability procedure, a home address (HoA) in a binding update (BU) packet is sent in a form of an encrypted option. In the BU process, an HoA index may also be bound. A corresponding mobile IPv6 communication system and a mobile node (MN), a correspondent node (CN), and a home agent (HA) in the communication system are also provided. Thus, the HoA appears only once in an encrypted form in a packet sent to the CN in the BU process, thereby improving the security of the HoA in the BU process.
