Title (EN) METHOD AND SYSTEM FOR COMPONENT AUTHENTICATION IN A VEHICLE
(FR) PROCEDE ET SYSTEME D'IDENTIFICATION DE COMPOSANTS DANS UN VEHICULE
Abstract: front page image
(EN)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.
(FR)Un composant potentiel (400) destiné à être utilisé dans un véhicule (100) renferme une première clé cryptographique servant à établir une communication cryptographique avec le véhicule. Pour le véhicule (100) est reçue d'un organisme de certification une attestation qui associe une seconde clé cryptographique à un composant authentique. Le véhicule (100) utilise la seconde clé cryptographique dans le cadre d'une communication cryptographique et détermine si le composant potentiel (400) est authentique selon que la communication cryptographique est probante ou non.
