METHODS, DEVICES AND DATA STRUCTURES FOR TRUSTED DATA

摘要

A computer platform is provided that includes a trusted device which is protected against subversion and comprises one or more platform configuration registers (506). The computer platform is arranged to create an auditable record concerning a statement (503) attesting to the trustworthiness of particular software that is intended to be run on the platform. The statement (503) includes a digest of the software and has an associated signature produced over the statement by an attesting party using a private key of a public/private key pair. The computer platform uses the statement public key to verify (5.4) the statement (503) and then creates the auditable record of the statement by extending (5.5) a platform configuration register (506) with the value of the public key.
