Bit. Locker Wikipedia. Bit. Locker is a full disk encryption feature included with Windows Vista and later. It is designed to protect data by providing encryption for entire volumes. By default it uses the AES encryption algorithm in cipher block chaining CBC or XTS mode6 with a 1. CBC is not used over the whole disk it is applied to each individual sector. HistoryeditBit. Locker originated as a part of Microsofts Next Generation Secure Computing Base architecture in 2. Cornerstone,1. 01. Code Integrity Rooting, was designed to validate the integrity of Microsoft Windows boot and system files. When used in conjunction with a compatible Trusted Platform Module TPM, Bit. Locker can validate the integrity of boot and system files before decrypting a protected volume an unsuccessful validation will prohibit access to a protected system. Bit. Locker was briefly called Secure Startup prior to Windows Vista being released to manufacturing.

R2, adds the ability to encrypt removable drives. On Windows XP or Windows Vista, read only access to these drives can be achieved through a program called Bit. Locker To Go Reader, if FAT1. FAT3. 2 or ex. FAT filesystems are used. In addition, a new command line tool called manage bde replaced the old manage bde. Starting with Windows Server 2. Windows 8, Microsoft has complemented Bit. Locker with the Microsoft Encrypted Hard Drive specification, which allows the cryptographic operations of Bit. Locker encryption to be offloaded to the storage devices hardware. In addition, Bit. Locker can now be managed through Windows Power. Shell. 1. 9 Finally, Windows 8 introduced Windows To Go in its Enterprise edition, which Bit. Locker can protect. Device encryptioneditWindows Mobile 6. Windows RT and core edition of Windows 8. Bit. Locker that encrypts the whole system. Logging in with a Microsoft account with administrative privileges automatically begins the encryption process. The recovery key is stored to either the Microsoft account or Active Directory, allowing it to be retrieved from any computer. While device encryption is offered on all versions of 8. Bit. Locker, device encryption requires that the device meet the Instant. Go formerly Connected Standby specifications,2. RAM to protect against cold boot attacks and a TPM 2. Encryption modeseditThere are three authentication mechanisms that can be used as building blocks to implement Bit. Locker encryption 2. Transparent operation mode This mode uses the capabilities of TPM 1. Windows as normal. The key used for disk encryption is sealed encrypted by the TPM chip and will only be released to the OS loader code if the early boot files appear to be unmodified. The pre OS components of Bit. Locker achieve this by implementing a Static Root of Trust Measurementa methodology specified by the Trusted Computing Group TCG. This mode is vulnerable to a cold boot attack, as it allows a powered down machine to be booted by an attacker. User authentication mode This mode requires that the user provide some authentication to the pre boot environment in the form of a pre boot PIN or password. 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. The key may also be provided by a CCID for reading a cryptographic smartcard. Using CCID provides additional benefits beyond just storing the key file on an external USB thumb drive, because the CCID protocol hides the private key using a cryptographic processor embedded in the smartcard this prevents the key from being stolen by simply being read off the media on which it is stored. The following combinations of the above authentication mechanisms are supported, all with an optional escrow recovery key OperationeditBit. Locker is a logical volume encryption system. A volume spans part of a hard disk drive, the whole drive or more than one drive. When enabled, TPM and Bit. Locker can ensure the integrity of the trusted boot path e. BIOS and boot sector, in order to prevent most offline physical attacks and boot sector malware. In order for Bit. Locker to encrypt the volume holding the operating system, at least two NTFS formatted volumes are required one for the operating system usually C and another with a minimum size of 1. MB from which the operating system boots. Bit. Locker requires the latter to remain unencrypted3. Windows Vista this volume must be assigned a drive letter, while on Windows 7 that is not required. Unlike previous versions of Windows, Vistas diskpart command line tool includes the ability to shrink the size of an NTFS volume so that this volume may be created from already allocated space. A tool called the Bit. Locker Drive Preparation Tool is also available from Microsoft that allows an existing volume on Windows Vista to be shrunk to make room for a new boot volume and for the necessary bootstrapping files to be transferred to it. Once an alternate boot partition has been created, the TPM module needs to be initialized assuming that this feature is being used, after which the required disk encryption key protection mechanisms such as TPM, PIN or USB key are configured. The volume is then encrypted as a background task, something that may take a considerable amount of time with a large disk as every logical sector is read, encrypted and rewritten back to disk. The keys are only protected after the whole volume has been encrypted, when the volume is considered secure. Bit. Locker uses a low level device driver to encrypt and decrypt all file operations, making interaction with the encrypted volume transparent to applications running on the platform. Encrypting File System EFS may be used in conjunction with Bit. Locker to provide protection once the operating system is running. Microsoft Help Attribute Definition File Ubuntu Forums. Protection of the files from processes and users within the operating system can only be performed using encryption software that operates within Windows, such as EFS. Bit. Locker and EFS, therefore, offer protection against different classes of attacks. In Active Directory environments, Bit. Locker supports optional key escrow to Active Directory, although a schema update may be required for this to work i. Active Directory Services are hosted on a Windows version previous to Windows Server 2. Bit. Locker 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. By configuring a TPM to protect the trusted boot pathway, including the BIOS and boot sector, Bit. Locker can mitigate this threat. Note that some non malicious changes to the boot path may cause a Platform Configuration Register check to fail, and thereby generate a false warning.
