Opal Storage Specification
The Opal Storage Specification is a set of specifications for features of data storage devices 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.
The specification is published by the Trusted Computing Group Storage Workgroup.
Overview
The Opal SSC 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.
- 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
