USB Key Mode: The user must insert a USB device that contains a startup key into the computer to be able to boot the protected OS. Note that this mode requires that the BIOS on the protected machine supports the reading of USB devices in the pre-OS environment. BitLocker does not support smart cards for pre-boot authentication.

It is also responsible for generating the UID key on A9 or newer chips that protects user data at rest. [citation needed] It has its own secure boot process to ensure that it is completely secure. A hardware random number generator is also included as a part of this coprocessor. Each device's Secure Enclave has a unique ID that is fused into ...
The core of Disk Drill is a Recovery Vault technology which allows to recover data from a medium that was secured by Recovery Vault beforehand.
Multiple keys: Whether an encrypted volume can have more than one active key. Passphrase strengthening: Whether key strengthening is used with plain text passwords to frustrate dictionary attacks, usually using PBKDF2 or Argon2. Hardware acceleration: Whether dedicated cryptographic accelerator expansion cards can be taken advantage of.
Key escrow (also known as a "fair" cryptosystem) [1] is an arrangement in which the keys needed to decrypt encrypted data are held in escrow so that, ...
The alternative, appending the key using MAC = H(message ∥ key), suffers from the problem that an attacker who can find a collision in the (unkeyed) hash function has a collision in the MAC (as two messages m1 and m2 yielding the same hash will provide the same start condition to the hash function before the appended key is hashed, hence the ...
Upgrade to a faster, more secure version of a supported browser. It's free and it only takes a few moments:
An HSM in PCIe format. A hardware security module (HSM) is a physical computing device that safeguards and manages secrets (most importantly digital keys), and performs encryption and decryption functions for digital signatures, strong authentication and other cryptographic functions. [1]
