Is the TCG the only standards group working on security for storage?
No. The necessity for secure and trusted storage has been realized by a number of storage-related standards groups, including: SNIA, IEEE P1667, IEEE P1619, U3, OASIS, IETF and others. Throughout the several-year work effort of the TCG Storage Workgroup, the objective has been to develop a comprehensive and flexible trust architecture that could be applied to a variety of storage environments and requirements, such as those being contemplated by the referenced groups. The work of the TCG Storage WG is unique and complementary to these other groups.
