Abstract:
A system and method for cryptographically securing a device includes initializing a cryptographic processing circuit which includes provisioning a cryptographic key store associated with the cryptographic processing circuit with cryptographic key material; and establishing a first cryptographically secured connection between a main central processing unit of the autonomous device and the cryptographic processing circuit of the device; and implementing a cryptographic validation of resident firmware of the main central processing unit by validating a cryptographic digital signature ascribed to the resident firmware against an up-to-date cryptographic digital signature used for installing and/or updating the resident firmware of the main central processing circuit.

Claim (Index 19):
A device security method that cryptographically secures a computing components of a device, the device security method comprising:\n implementing a first cryptographic binding step of:\n at a physically secure location, using a master cryptographic key by a first provisioning source recognized by a cryptographic processing circuit to initialize the cryptographic processing circuit by provisioning a cryptographic key store associated with the cryptographic processing circuit of the device with cryptographic key material; \n implementing a second cryptographic binding step:\n establishing a first cryptographically secured pairing between a main central processing unit of the device and the cryptographic processing circuit of the device by exclusively exchanging one or more cryptographic keys between the cryptographic processing circuit and the main central processing unit; \n implementing a third cryptographic binding step:\n establishing a second cryptographically secured pairing between the main central processing unit and resident firmware of the main central processing unit by cryptographically validating by the main central processing unit a cryptographic signature ascribed to the resident firmware; and \n implementing a fourth cryptographic binding step:\n generating by the first provisioning source a second master cryptographic key for a second provisioning source based on a master cryptographic key of the first provisioning source.
