Abstract
Cryptography is used to validate the security of a vehicle. An authentication system integrated in a zone master Electronic Control Unit (ECU) of a predefined zone requests pre-allocated signed unique cryptographic key shares from each of multiple primary ECUs associated with the zone master ECU, when there is an authentication requirement. Thereafter, the authentication system computes a first unique signature of the predefined zone using a predefined number of the key shares and verifies the validity of the computed first unique signature using a public key. Finally, the verified first unique signature is provided to a vehicle master ECU associated with the zone master ECU, to enable it to activate safety functionalities associated with the primary ECUs. Thereafter, the same method is repeated for multiple secondary ECUs. In this way, achievement of fast, non-sequential, and single step validation of vehicle security is enabled.
