METHOD AND SYSTEM FOR COMPONENT AUTHENTICATION IN A VEHICLE

摘要

A prospective component (400) for use in a vehicle (100) stores a first cryptographic key and utilizes the first cryptographic key in cryptographic communication with the vehicle. The vehicle (100) obtains from a certification authority a certification associating a second cryptographic key with an authentic component. The vehicle (100) utilizes the second cryptographic key in cryptographic communication and determines whether the prospective component (400) is the authentic component based on whether the cryptographic communication is successful.
