BitLocker and other full disk encryption systems can be attacked by a rogue boot manager. Once the malicious bootloader captures the secret, it can decrypt the Volume Master Key (VMK), which would then allow access to decrypt or modify any information on an encrypted hard disk.
However, this form of hardware security can result in data loss if activated accidentally by legitimate users and strong encryption algorithms essentially make such functionality redundant. As the encryption keys used in hardware encryption are typically never stored in the computer's memory, technically hardware solutions are less subject to ...
The attacker having physical access to a computer can, for example, install a hardware or a software keylogger, a bus-mastering device capturing memory or install any other malicious hardware or software, allowing the attacker to capture unencrypted data (including encryption keys and passwords) or to decrypt encrypted data using captured ...

Common uses are to verify platform integrity (to verify that the boot process starts from a trusted combination of hardware and software), and to store disk encryption keys. One of Windows 11's operating system requirements is TPM 2.0 implementation. Microsoft has stated that this is to help increase security against firmware attacks. [1]
The TCPA released detailed specifications for a trusted computing platform with focus on features such as code validation and encryption based on integrity measurements, hardware-based key storage, and machine authentication; these features required a new hardware component designed by the TCPA called the "Trusted Platform Module" (referred to ...
The Microsoft products Windows Vista, Windows 7, Windows 8 and Windows RT make use of a Trusted Platform Module to facilitate BitLocker Drive Encryption. [22] Other known applications with runtime encryption and the use of secure enclaves include the Signal messenger [23] and the e-prescription service ("E-Rezept") [24] by the German government.
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]
