WIRELESS COMMUNICATION SYSTEM AND WIRELESS COMMUNICATION METHOD

摘要

[PROBLEMS] To provide a technique for effectively avoiding DoS attacks and a terminal seeking performed with an identification number being a target, without making any significant changes to the communication system. [MEANS FOR SOLVING PROBLEMS] In a wireless communication system, for any one of wireless communication terminals, in accordance with the control of a control communication processing part (113) of an access point, a hash function calculating part (112) uses a current identification number, a hash key and a random number to generate a third identification number to be updated next, and the control communication processing part (113) transmits an update instruction signal, which includes the random number, to the wireless communication terminal, and updates the current identification number stored in an identification number storing part (121) to a second identification number. When receiving the update instruction signal, the wireless communication terminal updates the current identification number to the second identification number, and a hash function calculating part uses the current identification number, which is stored in a local wireless communication terminal number storing part, the hash key and the random number to generate the third identification number.
