To provide an authentication system, an in-vehicle authentication system, and an authentication method that can shorten the response time to users' operations.SOLUTION: An authentication system includes: a first communication device having a first transmitting unit that communicates in a first frequency band and a first transmitting/receiving unit that communicates in a second frequency band; and a second communication device having a first receiving unit that communicates in the first frequency band and a second transmitting/receiving unit that communicates in the second frequency band. The first communication device transmits a command in the first frequency band from the first transmitting unit. When receiving the command with the first receiving unit, the second communication device activates the second transmitting/receiving unit to generate an authentication key for a response signal, and the response signal in the second frequency band including the generated authentication key is transmitted from the second communication device.SELECTED DRAWING: Figure 3
【課題】ユーザの操作に対する応答時間を短縮可能な認証システム、車載認証システム、及び認証方法を提供する。【解決手段】認証システムは、第１周波数帯で通信する第１送信部と、第２周波数帯で通信する第１送受信部とを有する第１通信装置と、前記第１周波数帯で通信する第１受信部と、前記第２周波数帯で通信する第２送受信部とを有する第２通信装置とを含み、前記第１通信装置は、前記第１送信部から前記第１周波数帯のコマンドを送信し、前記第２通信装置は、前記第１受信部で前記コマンドを受信すると、前記第２送受信部を起動してレスポンス信号用の認証鍵を生成し、生成した認証鍵を含む前記第２周波数帯のレスポンス信号を前記第２通信装置から送信する。【選択図】図３
