Enclosed hard disk drive FDE; Removable hard disk drive FDE; Bridge and Chipset (BC) FDE; Hardware designed for a particular purpose can often achieve better performance than disk encryption software, and disk encryption hardware can be made more transparent to software than encryption done in software. As soon as the key has been initialised ...
Disk encryption is a technology which protects information by converting it into code that cannot be deciphered easily by unauthorized people or processes. Disk encryption uses disk encryption software or hardware to encrypt every bit of data that goes on a disk or disk volume. It is used to prevent unauthorized access to data storage. [1]
Starting with Windows Server 2012 and Windows 8, Microsoft has complemented BitLocker with the Microsoft Encrypted Hard Drive specification, which allows the cryptographic operations of BitLocker encryption to be offloaded to the storage device's hardware, for example, self-encrypting drives.
Disk encryption usually includes all aspects of the disk, including directories, so that an adversary cannot determine content, name or size of any file. It is well suited to portable devices such as laptop computers and thumb drives which are particularly susceptible to being lost or stolen. If used properly, someone finding a lost device ...
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.
Disk encryption is a special case of data at rest protection when the storage medium is a sector-addressable device (e.g., a hard disk). This article presents cryptographic aspects of the problem. This article presents cryptographic aspects of the problem.
