Opal Storage Specification

From Wikipedia, the free encyclopedia
Jump to: navigation, search

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[edit]

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[edit]

The Opal SSC encompasses these functions:

  • Security provider support
  • Interface communication protocol
  • Cryptographic features
  • Authentication
  • Table management
  • Access control and personalization
  • Issuance
  • SSC discovery

Opal SSC features[edit]

  • Security Protocol 1 support
  • Security Protocol 2 support
  • Communications
  • Protocol stack reset commands
