Abstract
Embodiments of the disclosure implement techniques to create secure Original Equipment Manufacturer (OEM) identifiers. In one embodiment, a processing system is disclosed. The processing system includes a memory to store an Original Equipment Manufacturer (OEM) key and a processing device, operatively coupled to the memory. The processing device is to receive the OEM key for an OEM system as input to a cryptographic hash function. A device key is produced by applying the cryptographic hash function to the OEM key and a global key associated with a vendor of the OEM system. The device key is provided to a security firmware device to authenticate the OEM system.
