Abstract: Examples described herein relate to a network interface device that includes first circuitry to negotiate supported timestamp parameters and selectively translate a timestamp associated with a packet based on the timestamp parameters and second circuitry to cause transmission of the packet based on the translated timestamp. In some examples, selectively translate a timestamp associated with a packet based on the timestamp parameters includes translates a value of the timestamp in a transmit descriptor associated with the packet.

Abstract: 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.
