Abstract
An opportunity for a computing device to participate in a secure session with a particular domain is identified. A domain identifier of the particular domain is received and a secured microcontroller of the computing device is used to identify a secured, persistent hardware identifier of the computing device stored in secured memory of the computing device. A secure identifier is derived for a pairing of the computing device and the particular domain based on the hardware identifier and domain identifier of the particular domain and the secure identifier is transmitted over a secured channel to the particular domain. The particular domain can verify identity of the computing device from the secure identifier and apply security policies to transactions involving the computing device and the particular domain based at least in part on the secure identifier.
