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.
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. BitLocker and EFS, therefore, offer protection against different classes of attacks. In Active Directory environments, BitLocker supports optional key escrow to Active Directory, although a schema update may be required for this to work i.
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.
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. All these attacks require physical access to the system and are thwarted by a secondary protector such as a USB flash drive or PIN code. Although the AES encryption algorithm used in BitLocker is in the public domain , its implementation in BitLocker, as well as other components of the software, are proprietary ; however, the code is available for scrutiny by Microsoft partners and enterprises, subject to a non-disclosure agreement.
According to Microsoft sources, [48] BitLocker does not contain an intentionally built-in backdoor , i. In , the UK Home Office expressed concern over the lack of a backdoor and tried entering into talks with Microsoft to get one introduced. Niels Ferguson's position that "back doors are simply not acceptable" [50] is in accordance with Kerckhoffs's principle. Stated by Netherlands born cryptographer Auguste Kerckhoffs in the 19th century, the principle holds that a cryptosystem should be secure, even if everything about the system, except the key , is public knowledge.
In October , it was reported that a flaw ROCA vulnerability in a code library developed by Infineon , which had been in widespread use in security products such as smartcards and TPMs, enabled private keys to be inferred from public keys.

March 22, Archived from the original PPT on August 27, Without the key, work may require that the machine be reimaged and all data will be lost since we are unable to access encrypted information.
The only time your BitLocker key should be required is if your machine encounters and issue and maintenance needs to be performed outside of Windows or by removing the hard drive.

Main Menu. You can print it, save it as a file to your hard drive, save it as a file to a USB drive, or save the key to your Microsoft account. Why You Should Encrypt Your Files The nightmare situation would be if your laptop was stolen and had a million social security numbers, or bank information, stored on it.
The TPM is a smartcard-like module on the motherboard that is installed in many newer computers by the computer manufacturer. BitLocker stores its recovery key in the TPM version 1. While enabling BitLocker, a recovery key is generated. The recovery key is used to gain access to your computer should you forget your password. After the recovery key is generated you will be prompted to restart the machine.
Once you complete the steps, the drive will start using encryption. If the drive already had data, the process could take a long time to complete. Alternatively, you can also use the "BitLocker To Go" feature to encrypt removable drives such as USB flash and external drives connected to your computer. When using encryption, always try to start with an empty drive to speed up the process, then the data will encrypt quickly and automatically.
In addition, similar to the feature of the operating system drive, you will get the same additional options and a few more, including:. Once you complete the steps, the decryption process will begin, and it will take some time to complete depending on the amount of data.

See all comments Of course the best BitLocker method is with an eDrive, setup during a clean Windows installation.
That way the encryption is offloaded to the drive. But this is second best. Definitely worth enabling if you can in case your device is ever stolen. But make sure you have a good backup mechanism in place. Definitely recommend backing up encryption key to Microsoft account nothing is worse than recovering or reseting your computer and having to wipe everything because you can't find your BitLocker key.
Backing it up to your Microsoft account makes it simple and easy to recover.
