BitLocker is a full volume encryption feature included with Microsoft Windows versions starting with Windows Vista. It is designed to protect data by providing encryption for entire volumes . By default, it uses the Advanced Encryption Standard (AES) algorithm in cipher block chaining (CBC) or " xor–encrypt–xor (XEX) -based Tweaked codebook ...
Microsoft released BitLocker Countermeasures [3] defining protection schemes for Windows. For mobile devices that can be stolen and attackers gain permanent physical access (paragraph Attacker with skill and lengthy physical access) Microsoft advise the use of pre-boot authentication and to disable standby power management.
Crypto-shredding is the practice of 'deleting' data by (only) deleting or overwriting the encryption keys. When a cryptographic disk erasure (or crypto erase) command is given (with proper authentication credentials), the drive self-generates a new media encryption key and goes into a 'new drive' state.

On Windows 8.1, supporting InstantGo and having a Trusted Platform Module (TPM) 2.0 chip will allow the device to use a passive device encryption system. [4] [5] Compliant platforms also enables full BitLocker Device encryption. A background service that encrypts the whole system which can be found in 'Windows Security'>'Device Encryption' page ...
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 ...
LRW: The Liskov-Rivest-Wagner tweakable narrow-block mode, a mode of operation specifically designed for disk encryption. Superseded by the more secure XTS mode due to security concerns. [122] XTS: XEX-based Tweaked CodeBook mode (TCB) with CipherText Stealing (CTS), the SISWG (IEEE P1619) standard for disk encryption.
[8] [14] NGSCB has yet to fully materialize; however, aspects of it are available in features such as BitLocker of Windows Vista, Measured Boot and UEFI of Windows 8, [15] Certificate Attestation of Windows 8.1, [16] Device Guard of Windows 10. [17] and Device Encryption in Windows 11 Home editions, with TPM 2.0 mandatory for installation.
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]
