Abstract
A client platform can be verified prior to being granted access to a resource or service on a network by validating individual hardware and software components of the client platform. Digests are generated for the components of the client platform. The digests can be collected into an integrity report. An authenticator entity receives the integrity report and compares the digests with digests stored in either a local signature database, a global signature database in an integrity authority, or both. Alternatively, the digests can be collected and stored on a portable digest-collector dongle. Once digests are either validated or invalidated, an overall integrity/trust score can be generated. She overall integrity/trust score can be used to determine whether the client platform should be granted access to the resource on the network using a policy.
