Opal Storage Specification

The Opal SSC (Security Subsystem Class) is an implementation profile for Storage Devices (SD) 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. == Security ==

Radboud University researchers indicated in November 2018 that some hardware-encrypted SSDs, including some Opal implementations, had security vulnerabilities. == Implementers of SSC ==
