What other infrastructure specifications has TCG released and how do they relate to the PTS Specification?
A. The current set of infrastructure specifications represents a second phase of specifications, with the first phase infrastructure specifications published in 2005. The first phase specifications focused on the operational infrastructure required for a single system (containing to a TPM) to function, allowing applications to make use of the basic features of the TPM. These specifications focused on key management, backup of keying material, certificate issuance and management, and others. In the current (second phase) specifications the focus is on the infrastructure support required for one platform to attest its state to another platform, which is a core value proposition of trustworthy computing. Thus, the current set of specifications includes a common architecture for understanding attestation using a TPM, as well as an interface to a measurement agent (the PTS) that can measure state, issue a report and verify attestations. The PTS builds on these previous first phase infrastru
The new set of infrastructure specifications represents a second phase of specifications, with the first phase infrastructure specifications published in 2005. The earlier specifications provided infrastructure support for the operations of a platform with a TPM. These include crucial functions such as key and certificate management for the TPM hardware, the credentials profile for TPM and platform credentials, as well as the underlying infrastructure architecture for trusted platforms. The PTS builds on these other infrastructure specifications, and make use of a number of crucial functionalities provided by these specifications. For example, when a PTS agent measures the integrity of a platform and reports its status, it makes use of the TPM-related credentials to provide authenticity of the report and the root of trust provided by the TPM.
