METHOD, DEVICE, AND SYSTEM FOR PROTECTING AND SECURELY DELIVERING MEDIA CONTENT

摘要

A method, device, and system for protecting and securely delivering media content includes configuring a memory controller of a system-on-a-chip (SOC) to establish a protected memory region, authenticating a firmware of a hardware peripheral using a security engine of the SOC, and storing the authenticated firmware in the protected memory region. The security engine may authenticate the firmware by authenticating a peripheral cryptographic key used to encrypt the firmware. Only authenticated hardware peripherals may access the protected memory region.
