Hardware Trust Anchors in Sp-enabled Processors

A trust system and method is disclosed for use in computing devices in which a central Authority shares secrets and sensitive data with users of the respective devices. The secrets and data are protected by hardware-rooted encryption and cryptographic hashing, and can be stored securely in untrusted storage Hardware-protected keys and other secrets further protect the confidentiality and/or integrity of any amount of other information by the use of strong encryption and/or keyed-hashing, respectively. The system provides access to third party secrets from the computing devices In one embodiment, the hardware-rooted encryption and hashing each use a single hardware register fabricated as part of the computing device's processor. The secret data is protected while in the device even during operating system malfunctions and becomes non-accessible from storage according to various rules.
