Abstract
A communication system (1) includes an anonymizing device (100) and a server (200). The anonymizing device (100) generates an anonymous address based on a prefix acquired from the server (200), receiving a packet transmitted from a communication node (300), rewrites a source address of the received packet into an anonymous address, encapsulates the received packet, and sends the packet to a second network (600) using the address of the anonymizing device (100) as a source address of the encapsulated packet and the address of the server (200) as a destination address. Then, receiving the encapsulated packet transmitted from the anonymizing device (100), the server (200) decapsulates the encapsulated packet and sends the packet to the second network (600). High anonymity can be thereby assured.
