Authentication method for appliance to motor vehicle
The granted patent (Publication Number: US11974123B2) discloses a method for authenticating an appliance to a motor vehicle through a series of steps. The method involves the use of a Password Authenticated Connection Establishment (PACE) method to establish a session key between the appliance and the motor vehicle. Subsequently, a communication key is generated by both the motor vehicle and the appliance based on the session key and encrypted values, enabling encrypted communication between the two entities.
Furthermore, the patent claims specify additional details such as the encryption of the second one-way hash with respect to a predetermined base point of an encryption system, the use of elliptic curves for encryption using the communication key, and the association of the appliance with a specific user. The method ensures that the appliance is securely linked to the motor vehicle when encrypted communication based on the communication key is established, providing a secure and reliable authentication process for various types of appliances, including mobile and personal appliances.
