Abstract
Systems and techniques for trustworthy peripheral transfer of ownership are described herein. A unique peripheral identifier may be received from an ownership manifest of the peripheral device. The unique peripheral identifier may be transferred to a bus controller for a bus between the computing device and the peripheral device. A measurement may be received from the peripheral device by the basic input and output system of the computing device. A measurement of a computing platform of the computing device may be generated. The measurement may indicate peripheral devices interconnected to the computing device. Data transfer between the peripheral device and the computing device may be allowed via the bus based on validation of the measurement of the computing platform against a platform configuration register of the computing device.
