Abstract
Systems and methods for facilitating a trusted platform module (TPM) or other protector mechanism that provides a device with a trusted device capability store. To provide the device with a trusted device capability store, a fingerprint of an endorsement key that is associated with the TPM or other protector mechanism can be imprinted into firmware of the device. By imprinting the fingerprint into the firmware, the device can determine whether or not the TPM or other protector mechanism the device is communicating with is the TPM or other protector mechanism associated with the device. The TPM or other protector mechanism can include the endorsement key, the trusted device capability store, and an access policy. The trusted device capability store can include one or more capabilities associated with the device. The access policy can indicate both unauthorized read access and authorized write access associated with the TPM or other protector mechanism.
