WIRELESS COMMUNICATIONS TERMINAL, SERVER UNIT, AND WIRELESS COMMUNICATIONS SYSTEM

摘要

PROBLEM TO BE SOLVED: To reduce call charges required for a public line in a continues long time game.

SOLUTION: The wireless communication terminal 101-1 encrypts game data by using the encryption key of a wireless communication terminal 101-N and sends to the wireless communication terminal 101-N via an ad hoc network 104 formed of wireless communication terminals 101 other than the wireless communication terminal 101-1 and the wireless communication terminal 101-N. The wireless communication terminal 101-N receives game data sent from the wireless communication terminal 101-1 and decrypts the data by using the encryption key of the wireless communication terminal 101-1 previously sent to the wireless communication terminal 101-N by the wireless communication terminal 101-1.
