The Opal Storage Specification is a set of specifications for features of data storage devices (such as hard disk drives and solid state 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.
Usually referred to as self-encrypting drive (SED).HDD FDE is made by HDD vendors using the OPAL and Enterprise standards developed by the Trusted Computing Group. [1] Key management takes place within the hard disk controller and encryption keys are 128 or 256 bit Advanced Encryption Standard (AES) keys.
The Trusted Computing Group Opal Storage Specification provides industry accepted standardization for self-encrypting drives. External hardware is considerably faster than the software-based solutions, although CPU versions may still have a performance impact [ clarification needed ] , and the media encryption keys are not as well protected.
ClevX is introducing a new self-encrypting platform, available for internal and external SSDs and HDDs.
The jury determined that several Western Digital self-encrypting hard drive products infringe a SPEX Technologies patent covering data encryption innovations, a SPEX attorney said in an email. San ...
Opal Storage Specification specifies a command set for self-encrypting drives and cryptographic erase, available in addition to command-set methods. The drive usually performs fast cryptographic erasure when data is encrypted, and a slower data erasure by overwriting otherwise. [18] SCSI allows for asking for a specific type of erasure. [17]
