TCG Storage, Opal, and NVMe
The Trusted Computing Group (TCG) and NVM Express have collaborated on a whitepaper. The Opal ñFamilyî of specifications published by the TCG provides a scalable infrastructure for managing encryption of user data in a Storage Device, as well as extensibility to enable features beyond ñdata at rest protectionî.
This joint whitepaper describes the Trusted Computing Group Storage Work Group; the Opal, Opalite, and Pyrite specifications for managing encryption of user data; drawbacks of alternatives to the Opal family of specs; and the areas where NVMe Work Group and TCG Work Group can collaborate to provide enhanced solutions that combine the benefits of the two specification.
