Bitlocker Full Disk Encryption
Anotace:
V současném moderním světě informační éry, informační bezpečnosti hraje zásadní roli při ochraně důvěrnosti citlivých osob informace. Bezpečnost informací hraje důležitou roli při zajišťování informací jako schopnosti útoku a protivníka se v průběhu let značně zvýšily. Bezpečnost jakýkoli informační systém může být klasifikován jako bezpečnost během komunikace / doprava, bezpečnost při zpracování a …více
Abstract:
In the current modern world of information era, Information security plays a vital role in protecting the confidentiality of the sensitive information. The information security has a major role to play in securing the information as the attack surface and adversary capabilities have increased enormously over the years. The security of any information system can be classified as security during communication …více

The first block of plain text will be encrypted using a prefixed InitializationVector (IV) bits. • Xor-encrypt-xor (XEX) A type of tweakable encryption mode for disk encryption wherein a combination of the sector address and index of the block within the sector are used for encryption. • XEX-based tweaked-code book mode with cipher text stealing (XTS) Cipher text stealing provides XEX support for sectors with size not divisible by block size for example 520-byte sectors and 16-byte blocks. • CBC XTS A type of encryption mode which is a combination of CBC encryption mode with XTS features. • Basic Input Output System (BIOS) BIOS is a program running from a non-volatile memory responsible for initializing the system hardware and providing its essential interface to Operating System. • Unified Extensible Firmware Interface (UEFI) UEFI is an advanced version of BIOS which supports more number of peripherals provides option of dynamic programming through external interface with user friendly graphical features.
