Wireless communication system and terminal-device authentication method in wireless communication system

摘要

A wireless communication system includes code transmitters (20a, 20b) each configured to transmit a time-varying code; code receivers (30a, 30b) each configured to receive the time-varying codes transmitted from the code transmitters (20a, 20b) and generate a fingerprint based on the received time-varying codes, the fingerprint being unique to a space where the time-varying codes are receivable; and terminal devices (40a, 40b) configured to establish wireless communication connection therebetween with authentication. The terminal devices (40a, 40b) are connected to the code receivers (30a, 30b), respectively. Each terminal device (40a, 40b) includes a fingerprint acquiring unit configured to acquire the fingerprint from the code receiver (30a, 30b), a wireless communication unit configured to transmit and receive the fingerprint via wireless communication, and an authentication unit configured to authenticate another terminal device if the fingerprint received from the another terminal device matches the fingerprint acquired from the code receiver connected thereto.

主权项

1. A wireless communication system, comprising:
a plurality of code transmitters each configured to transmit a time-varying code, the time-varying codes transmitted from the code transmitters being different from each other; a plurality of code receivers each configured to receive the time-varying codes transmitted from the code transmitters and generate a fingerprint based on the received time-varying codes, the fingerprint being unique to a space where the time-varying codes are receivable; and a plurality of terminal devices configured to establish wireless communication connection therebetween with authentication, the terminal devices being connected to the code receivers, respectively, wherein each of the terminal devices includes
a fingerprint acquiring unit configured to acquire the fingerprint from the code receiver connected thereto,a wireless communication unit configured to transmit and receive the fingerprint via wireless communication, andan authentication unit configured to authenticate, as a communications partner, another one of the terminal devices if the fingerprint received by the wireless communication unit from the another one of the terminal devices matches the fingerprint acquired by the fingerprint acquiring unit from the code receiver connected thereto.
