Title:
COMMUNICATION METHOD, COMMUNICATION SYSTEM, ANONYMIZING DEVICE, AND SERVER
Document Type and Number:
WIPO Patent Application WO/2010/100850
Kind Code:
A1
Abstract:
A communication system (1) comprising an anonymizing device(100) and a server (200). The anonymizing device (100) generates an anonymous address based on a prefix obtained from the server (200); rewrites the source address of a packet, when one transmitted from a communication node (300) has been received, to an anonymous address; then, after encapsulating the received packet, sends the packet to a second network (600) using the address of the anonymizing device (100) as the source address of the encapsulated packet and the address of the server (200) as the destination address. Then, when the server (200) has received the encapsulated packet transmitted from the anonymizing device (100), the server (200) de-capsulates the encapsulated packet and transfers the packet to the second network (600). Due to this, high anonymity can be secured.
