Abstract: A device includes a microcontroller, memory including secure memory to store a private key, a set of registers, and an authentication engine. The set of registers includes a write mailbox register and a read mailbox register, and message data is to be written to the write mailbox register by a host system. The message data includes at least a portion of a challenge request, and the challenge request includes a challenge by the host system to authenticity of the device. The authentication engine generates a response to the challenge, where the response includes data to identify attributes of the device and a signature generated using the private key. The authentication engine causes at least a portion of the response to be written to the read mailbox register to be read by the host system.

Abstract: Techniques and apparatuses for issuance of license upgrades for hardware components in the field, as well as the hardware components, are described. In one embodiment, for example an apparatus may include processor circuitry and memory in communication with the processor circuitry, wherein the memory contains a configuration data block and license data block, the configuration data block being read from the memory via a licensing apparatus and the licensing data block being written to the memory by the licensing apparatus. The processor may include executable code to process the licensing data block to facilitate an upgrade of the capabilities of the processor circuitry.
