Title:
マルチホップ通信システムおよびその移動端末、経路制御サーバならびに経路確立方法
Document Type and Number:
Japanese Patent JP4526079
Kind Code:
B2
Abstract:

To provide a multi-hop communication system and a mobile terminal thereof capable of securely realizing multi-hop communication when at least one of a plurality of terminals acting like relay stations is located within the zone of an infrastructure network, and to provide a routing control server and a routing establishment method.

A transmission terminal S applies flooding of an RREQ to whole mobile terminals, the RREQ resulting from encrypting a sender address IPs and a destination address IPt by a public key KRMp, and the mobile terminal X in a zone receiving the RREQ requests a server RM to assign anonymous addresses FWs, FWt to the mobile terminal X. The server RM interprets the sender address IPs and the destination address IPt by using a private key KRMs, encrypts them again by using a shared key KRM_t unique to the destination terminal T, and returns the re-encrypted shared key KRM_t together with the anonymous addresses FWs, FWt to the mobile terminal X in the form of a FWREP. The mobile terminal X registers the addresses IPs, IPt and the anonymous addresses FWs, FWt re-encrypted by using the shared key KRM_t to an RREQ and applies flooding of the resulting RREQ to the whole mobile terminals.
