BitLocker originated as a part of Microsoft's Next-Generation Secure Computing Base architecture in 2004 as a feature tentatively codenamed "Cornerstone" [4] [5] and was designed to protect information on devices, particularly if a device was lost or stolen.
On Windows 8.1, supporting InstantGo and having a Trusted Platform Module (TPM) 2.0 chip will allow the device to use a passive device encryption system. [4] [5] Compliant platforms also enables full BitLocker Device encryption. A background service that encrypts the whole system which can be found in 'Windows Security'>'Device Encryption' page ...

BitLocker is the combination of these features; "Cornerstone" was the codename of BitLocker, [85] [86] and BitLocker validates pre-boot firmware and operating system components before boot, which protects SYSKEY from unauthorized access; an unsuccessful validation prohibits access to a protected system.

These octets are a host ID in the form allowed by the specified address family. Later, the UUID was extended by combining the legacy family field with the new variant field. Because the family field only had used the values ranging from 0 to 13 in the past, it was decided that a UUID with the most significant bit set to 0 was a legacy UUID.
Field upgrade is the TCG term for updating the TPM firmware. The update can be between TPM 1.2 and TPM 2.0, or between firmware versions. Some vendors limit the number of transitions between 1.2 and 2.0, and some restrict rollback to previous versions. [citation needed] Platform OEMs such as HP [86] supply an upgrade tool.
BitLocker, formerly known as "Secure Startup", this feature offers full disk encryption for the system volume. Using the command-line utility, it is possible to encrypt additional volumes. Bitlocker utilizes a USB key or Trusted Platform Module (TPM) version 1.2 of the TCG specifications to store its encryption key.
The number must be copied into the PASSCODE field by hand. Disconnected tokens have neither a physical nor logical connection to the client computer. They typically do not require a special input device, and instead use a built-in screen to display the generated authentication data, which the user enters manually themselves via a keyboard or ...
