ABSTRACT:
A host computing platform20provides one or more computing environments24and includes a trusted device213arranged to form an integrity metric individual to each computing environment24.The integrity metric is provided to a user10in response to an integrity challenge, signed for authentication using a signature key213held by the trusted device. In one embodiment the trusted device213selects a signature key unique to the computing environment24,or in a second embodiment the trusted device forms the signed integrity metric including an identity label, in each case such that the user10can verify that the signed integrity metric corresponds to the expected computing environment24.
