Abstract
Communication of information via an in-band channel using a trusted configuration space is provided. The introduction of using a trusted configuration space associated with a computer bus system, such as PCI Express® (PCIe™), for example, enables the design of trusted computing platforms capable of providing compliant devices with assurance that their trusted configuration registers can only be accessed by software running in the trusted software environment. Establishing device trust in the software that initiates trusted configuration requests makes it possible to secure and control access to certain secret, sensitive, or personally-identifiable information these devices may contain (e.g., a uniquely-identifying public key, as described above or certificate which the device provides for revocation purposes).
