METHODS AND SYSTEMS FOR PROVIDING ADVANCED SECURE BOOT FEATURES TO LIMITED-RESOURCE PERIPHERAL DEVICES BY USING A SECURE PROCESSOR

摘要

A method of authenticating software of a peripheral device may include obtaining, with a secure processor, a cryptographic key for a peripheral device; storing, on the secure processor, the cryptographic key for the peripheral device; sending, by the secure processor, the cryptographic key to the peripheral device; obtaining, by the secure processor, a software for the peripheral device; authenticating, by the secure processor, the software of the peripheral device to provide authenticated software; and sending, by the secure processor, the authenticated software to the peripheral device based on the cryptographic key.
