The "Transparent operation mode" and "User authentication mode" of BitLocker use TPM hardware to detect whether there are unauthorized changes to the pre-boot environment, including the BIOS and MBR. If any unauthorized changes are detected, BitLocker requests a recovery key on a USB device.
Key escrow (also known as a "fair" cryptosystem) [citation needed] is an arrangement in which the keys needed to decrypt encrypted data are held in escrow so that, under certain circumstances, an authorized third party may gain access to those keys.
In cryptanalysis and computer security, password cracking is the process of guessing passwords [1] protecting a computer system.A common approach (brute-force attack) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password. [2]
On devices with Windows' BitLocker disk encryption enabled, which corporations often use to increase security, fixing the problem was exacerbated because the 48-digit numeric Bitlocker recovery keys (unique to each system) required manual input, with additional challenges supplying the recovery keys to end users working remotely. Additionally ...
These metrics can be used to detect changes to previous configurations and decide how to proceed. Examples of such use can be found in Linux Unified Key Setup (LUKS), [33] BitLocker and PrivateCore vCage memory encryption. (See below.) Another example of platform integrity via TPM is in the use of Microsoft Office 365 licensing and Outlook ...
