BitLocker is a logical volume encryption system. (A volume spans part of a hard disk drive, the whole drive or more than one drive.) When enabled, TPM and BitLocker can ensure the integrity of the trusted boot path (e.g. BIOS and boot sector), in order to prevent most offline physical attacks and boot sector malware. [38]

dm-crypt is a transparent block device encryption subsystem in Linux kernel versions 2.6 and later and in DragonFly BSD.It is part of the device mapper (dm) infrastructure, and uses cryptographic routines from the kernel's Crypto API.
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]
Key management takes place within the hard disk controller and encryption keys are 128 or 256 bit Advanced Encryption Standard (AES) keys. Authentication on power up of the drive must still take place within the CPU via either a software pre-boot authentication environment (i.e., with a software-based full disk encryption component - hybrid ...
The symmetric encryption algorithm used will vary depending on the version and configuration of the operating system; see Algorithms used by Windows version below. The FEK (the symmetric key that is used to encrypt the file) is then encrypted with a public key that is associated with the user who encrypted the file, and this encrypted FEK is ...
The Linux Unified Key Setup (LUKS) is a disk encryption specification created by Clemens Fruhwirth in 2004 and originally intended for Linux.. LUKS implements a platform-independent standard on-disk format for use in various tools.
Some disk encryption software (e.g., TrueCrypt or BestCrypt) provide features that generally cannot be accomplished with disk hardware encryption: the ability to mount "container" files as encrypted logical disks with their own file system; and encrypted logical "inner" volumes which are secretly hidden within the free space of the more obvious ...
