摘要

PROBLEM TO BE SOLVED: To enable secure communication among a plurality of game consoles through a local area network.

SOLUTION: A system architecture supports a secure communication protocol of three stages. The first stage is related to the formation of a peculiar shared key on an authentic game console which executes an authentic game title. In the second stage, the finding of an already existing game session which is hosted by a "host" game console 100-1 is tried by performing a simultaneous transmissive communication for a demand through the local area network by "client" consoles 100-2 to 1002-g. The third stage is related to a key exchange in which the clients 100-2 to 1002-g and the host console 100-1 exchange data which are used for guiding out one or a plurality of secrets in order to protect a future communication.
