Title:
モバイルIPネットワークにおけるルート最適化
Document Type and Number:
Japanese Patent JP4913909
Kind Code:
B2
Abstract:
The present invention the present invention concerns a method for optimizing a route between a mobile node and a correspondent node in mobile Internet protocol networks. The mobile node is served by an anchor point being a node, e.g. a mobile IP home agent. According to the method the anchor point generates a Multi-key Cryptographically Generated Address (MCGA) for the mobile node. The MCGA is generated using at least the public keys of the mobile node and the anchor point. The anchor point assigns and registers the generated MCGA as a home address for the mobile node and sends a binding update message to the correspondent node on behalf of the mobile node. The binding update message includes at least a signature of the MCGA signed by the anchor point. Thereby route optimization can be performed such that data packets can be exchanged between the mobile node and the correspondent node without routing the packets via the anchor point.
