The Trusted Platform Module: Benefits for Data-at-Rest Encryption
The Trusted Computing Group develops open specifications for building blocks that enable secure computing. Their most significant publication to date is the Trusted Platform Module (TPM), a specification for an embeddable microcontroller that provides a number of security services for the benefit of its host platform. The TPM specification has now been implemented by a number of IC vendors. While TPM functionality is not tied to any specific type of platform, adoption by PC vendors has been most significant to date.
