(A volume spans part of a hard disk drive, the whole drive or more than one drive.) When enabled, TPM and BitLocker can ensure the integrity of the trusted boot path (e.g. BIOS and boot sector), in order to prevent most offline physical attacks and boot sector malware. [38]
For example, a cold boot attack is used in situations where a system is secured and it is not possible to access the computer. [3] A cold boot attack may also be necessary when a hard disk is encrypted with full disk encryption and the disk potentially contains evidence of criminal activity. A cold boot attack provides access to the memory ...
The inserted hard drive FDE allows a standard form factor hard disk drive to be inserted into it. The concept can be seen on [7] This is an improvement on removing [unencrypted] hard drives from a computer and storing them in a safe when not in use. This design can be used to encrypt multiple drives using the same key.
Disk encryption usually includes all aspects of the disk, including directories, so that an adversary cannot determine content, name or size of any file. It is well suited to portable devices such as laptop computers and thumb drives which are particularly susceptible to being lost or stolen. If used properly, someone finding a lost device ...
Such a controller historically has been made in the form of a dongle that fits between a computer and an IDE or SCSI hard drive, but with the advent of USB and SATA, forensic disk controllers supporting these newer technologies have become widespread. Steve Bress and Mark Menz invented hard drive write blocking (US Patent 6,813,682).
Since disk encryption generally uses the same key for encrypting the whole drive, all of the data can be decrypted when the system runs. However, some disk encryption solutions use multiple keys for encrypting different volumes. If an attacker gains access to the computer at run-time, the attacker has access to all files.
The encryption method should not waste disk space (i.e., the amount of storage used for encrypted data should not be significantly larger than the size of plaintext). The first property requires defining an adversary from whom the data is being kept confidential. The strongest adversaries studied in the field of disk encryption have these ...
