Application: Authentication system, in-vehicle authentication system, and authentication method (Patent ID: US20230413044A1)
The patent filed by Alps Alpine Co Ltd describes an authentication system involving two communication devices, one transmitting a command in a first frequency band and the other generating an authentication key for a response signal in a second frequency band. The system includes features such as signal strength measurement signals, distance measurement requests, and position determination signals to ensure secure authentication between the devices. Additionally, power supply management is implemented to conserve energy during the authentication process.
The authentication system and method outlined in the patent claims involve a multi-step process where the first communication device transmits commands and signal strength measurement signals, while the second communication device responds with authentication keys and distance measurement signals. The system also includes provisions for position determination and power supply management to enhance security and efficiency during the authentication process. By incorporating these features, the patent aims to provide a robust and energy-efficient authentication system for various applications, including in-vehicle equipment and mobile devices.
