The Opal Storage Specification is a set of specifications for features of data storage devices (such as disk drives) that enhance their security. For example, it defines a way of encrypting the stored data so that an unauthorized person who gains possession of the device cannot see the data. That is, it is a specification for self-encrypting drives (SED).

The specification is published by the Trusted Computing Group Storage Workgroup.

Opal SSC overview

The Opal SSC (Security Subsystem Class) is an implementation profile for Storage Devices built to:

  • Protect the confidentiality of stored user data against unauthorized access once it leaves the owner's control (involving a power cycle and subsequent deauthentication).
  • Enable interoperability between multiple SD vendors.

    • Opal SSC functions

    The Opal SSC encompasses these functions:

  • Security provider support
  • Interface communication protocol
  • Cryptographic features
  • Authentication
  • Table management
