Abstract:
1. A wireless communication system for effecting communication between wireless terminals by structuring an ad hoc network without using an access point, wherein each of the wireless terminals comprises: a receiving unit which receives a beacon signal generated periodically from a wireless terminal of a communication party; an extracting unit which extracts network identification information contained in the beacon signal received by the receiving unit; a setting unit which automatically sets the extracted network identification information; and a session establishing unit which establishes a session by sending a communication request to the wireless terminal of the communication party by using the network identification information set by the setting unit; wherein each of the wireless terminals and the wireless terminal of the communication party comprise: a holding unit which holds a prime number and a primitive element which are common to the wireless terminals: a random number generating unit; and a common encryption key generating unit which generates a common encryption key by effecting communication between the wireless terminal and the wireless terminal of the communication party by using the prime number and the primitive element which are held in the holding unit and the random number generated by the random number generating unit.
