Title (EN) WIRELESS COMMUNICATION AUTHENTICITY DETERMINATION SYSTEM
(FR) SYSTÈME DE DÉTERMINATION D'AUTHENTICITÉ DE COMMUNICATION SANS FIL
(JA) 無線通信正否判定システム
Abstract:
(EN) In a first communication unit (2), two-way communication with a second communication unit (9) is performed using radio waves of the same frequency, the reception signal strength of a radio wave (24) sent from the second communication unit (9) is calculated as a first reception signal strength, and the first reception signal strength is reported to the second communication unit (9). In the second communication unit (9), the reception signal strength of a radio wave (28) with which the first reception signal strength was reported is calculated as a second reception signal strength, and the difference is calculated between the first reception signal strength and the second reception signal strength. The second communication unit (9) determines the communication authenticity of smart communication by confirming whether the difference is within a reference range.
(FR) Selon l’invention, dans une première unité de communication (2), une communication bidirectionnelle avec une seconde unité de communication (9) est exécutée au moyen d’ondes radio de la même fréquence, l’intensité de signal de réception d’une onde radio (24) envoyée par la seconde unité de communication (9) est calculée en tant qu’une première intensité de signal de réception, et la première intensité de signal de réception est rapportée à la seconde unité de communication (9). Dans la seconde unité de communication (9), l’intensité de signal de réception d’une onde radio (28) avec laquelle la première intensité de signal de réception a été rapportée, est calculée en tant qu’une seconde intensité de signal de réception, et la différence est calculée entre la première intensité de signal de réception et la seconde intensité de signal de réception. La seconde unité de communication (9) détermine l’authenticité de communication d’une communication intelligente en confirmant si la différence se situe dans une plage de référence.
(JA) 第1通信部(2)は同一周波数の電波で第2通信部(9)と双方向通信を行い、第2通信部(9)から送信された電波(24)の受信信号強度を第1受信信号強度として算出し、その第1受信信号強度を第2通信部(9)に通知する。第2通信部(9)は、第1受信信号強度が通知された電波(28)の受信信号強度を第2受信信号強度として算出し、第1受信信号強度と第2受信信号強度との差分を算出する。第2通信部(9)は、この差分が基準範囲にあるか否かを確認することにより、スマート通信の通信正否を判定する。
