Abstract: A supplier network device is provided and includes a supplier processor and memory that stores a credential package including information for a chip or a vehicle control module (VCM). The supplier processor: receives ID and signature public keys from the chip, where the ID and signature public keys correspond respectively to private keys stored in the chip; transmit the ID and signature public keys to a certificate authority processor of a vehicle manufacturer data center; and receive the credential package including signing certificates from the certificate authority processor prior to assembling the VCM. The supplier processor: reads the ID public key from the VCM subsequent to incorporating the chip in the VCM; identifies the credential package based on the ID public key; and based on the identifying of the credential package, programs the VCM with the signing certificates prior to installation of the vehicle control module in a vehicle.
