Authorisation method with certificate |
摘要 |
<p>In a process for insuring data integrity of software for a control unit of a motor vehicle, a central system (trust center) can issue certificates to authorized parties, enabling them to properly sign software for the control unit and import it into a vehicle to enable operation of the vehicle. For this purpose, the trust center (or the vehicle itself) provides a pair of control unit keys having a first and second key. The first key is stored during production of the vehicle in such a manner that it is accessible to the control unit. By means of the second key of the trust center, a first certificate for an authorized party (certificate holder) is signed.</p> |
