Application: Id-based control unit-key fob pairing (Patent ID: US20240106630A1)

The patent filed by Texas Instruments Inc. describes a method for pairing a key fob with a control unit using an ID authenticated key agreement protocol. The key fob generates encryption keys based on device identifications, receives encrypted control unit identifications, and operational keys to establish secure communication. The method involves erasing identification keys after key exchange to enhance security and includes executing authenticated challenge-response protocols based on the exchanged keys.

The claims associated with the patent detail the steps involved in the method, including encryption key generation, key exchange between devices, erasing identification keys, and executing challenge-response protocols. The method ensures secure pairing between the key fob and control unit, with additional features like triggering key changes and utilizing Advanced Encryption Standard (AES)-128 for protocols. The patent covers various scenarios such as pairing with access control systems, vehicle control units, and electronic devices like key fobs, emphasizing secure and efficient communication protocols for different applications.
