Abstract
A method for dependent trust in a computer system is provided. In this method, trust dependency relationships are defined among components of the computer system, specifying, for a component, which components it relies on in ensuring the integrity or confidentiality of its code or data. Subsequently, trust dependencies are resolved and the results are used in performing certain operations described in Trusted Computing Group standards including generating an attestation reply, sealing data, and unsealing data. In addition, methods for computing an integrity measurement for a Core Root of Trust for Measurement of a trust-dependent component are included. A system for dependent trust in a computer system is also described.
