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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Opal Storage Specification」の詳細全文を読む スポンサード リンク
