Abstract
A transparent trust validation of an unknown platform can be performed by communicationally coupling it to a trusted device, such as a portable peripheral device carried by a user, or one or more remote computing devices. Information from the unknown platform can be obtained by boot code copied to it from the trusted device and such information can be validated by the trusted device. The trusted device can then provide an encrypted version of decryption key to the boot code which can request the Trusted Platform Module (TPM) of the unknown platform to decrypt and return the decryption key. If the information originally obtained from the unknown platform and validated by the trusted device was authentic, the TPM will be able to provide the decryption key to the boot code, enabling it to decrypt an encrypted volume comprising applications, operating systems or other components.
