Starting with Windows 10 version 1511, however, Microsoft added a new FIPS-compliant XTS-AES encryption algorithm to BitLocker. [1] Starting with Windows 10 version 1803, Microsoft added a new feature called "Kernel Direct Memory access (DMA) Protection" to BitLocker, to protect against DMA attacks via Thunderbolt 3 ports.
The Encrypting File System (EFS) on Microsoft Windows is a feature introduced in version 3.0 of NTFS [1] that provides filesystem-level encryption.The technology enables files to be transparently encrypted to protect confidential data from attackers with physical access to the computer.
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]
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 Superseded by the more secure XTS mode due to security concerns.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.
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.
The software can create a virtual encrypted disk that works just like a regular disk but within a file. It can also encrypt a partition [6] or (in Windows) the entire storage device with pre-boot authentication. [7] VeraCrypt is a fork of the discontinued TrueCrypt project. [8] It was initially released on 22 June 2013.
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 ...
