As industry standard organizations, including the Trusted Computing Group, continue to address new use cases, platforms, environments, and other challenges related to attestation, it is important to strive for consistency across standards.  The Attestation work group (ATWG) aims to ensure that attestation related specifications, references, and guidance from TCG are consistent across work groups.  Attestation work group deliverables take a TCG-wide perspective to integrate existing attestation related work.  In addition, the ATWG provides a framework and terminology enabling TCG work groups to focus on WG-specific content and to avoid repetitive and potentially contradictory attestation terminology definitions and architecture.


Another important goal of the Attestation work group is to consider compatibility and interoperability with other industry efforts focused on attestation.
