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 1):
A system that cryptographically secures components of a printed circuit board assembly of a device, the system comprising:\n a printed circuit board assembly comprising:\n a main central processing circuit, \n a cryptographic processing circuit, and \n a physically secured cryptographic key store; \n a first provisioning source comprising a first provisioning computer that, at a time of manufacture:\n [1] provisions the main central processing circuit with resident firmware; and \n [2] cryptographically signs the resident firmware with a master cryptographic key; \n [3] provisions the physically secured cryptographic key store with asymmetric cryptographic key material, \n wherein, after provisioning the main central processing circuit and provisioning the physically secured cryptographic key store, establishing a first cryptographically secured communication channel between the main central processing circuit and the cryptographic processing circuit using the asymmetric cryptographic key material, and \n wherein the main central processing circuit uses the first cryptographically secured communication channel to control an operation of the cryptographic processing circuit.
