BitLocker support for TPM 2. TPM 2. Devices with TPM 2. For added security Enable the Secure Boot feature. This is because BitLocker will not unlock the protected drive until BitLocker's own volume master key is first released by either the computer's TPM or by a USB flash drive containing the BitLocker startup key for that computer. However, computers without TPMs will not be able to use the system integrity verification that BitLocker can also provide.
To help determine whether a computer can read from a USB device during the boot process, use the BitLocker system check as part of the BitLocker setup process. This system check performs tests to confirm that the computer can properly read from the USB devices at the appropriate time and that the computer meets other BitLocker requirements.
To turn on, turn off, or change configurations of BitLocker on operating system and fixed data drives, membership in the local Administrators group is required. Standard users can turn on, turn off, or change configurations of BitLocker on removable data drives.
If the hard disk is not first and you typically boot from hard disk, then a boot order change may be detected or assumed when removable media is found during boot. The boot order typically affects the system measurement that is verified by BitLocker and a change in boot order will cause you to be prompted for your BitLocker recovery key.
For the same reason, if you have a laptop with a docking station, ensure that the hard disk drive is first in the boot order both when docked and undocked. Feedback will be sent to Microsoft: By pressing the submit button, your feedback will be used to improve Microsoft products and services. Doron Ben Cohen. Microsoft BitLocker is a Windows native security feature that will encrypt everything on the drive that Windows is installed upon. You can encrypt PCs or drives, and full-volume encryption will ensure that only those with the correct encryption key will be able to decrypt and access your files and information.
BitLocker will create a recovery key for your hard drive, so that every time you start up your computer, a specific pin number will be needed in order to gain access. There will also be a recovery key that can be used if for any reason you forget the password.
You should make sure to save this recovery key somewhere safe that is not the PC in use. The aim of BitLocker is to protect computers and drives against data breaches and intrusions. The main benefits are:. Not all computers or drives can use BitLocker. Windows currently supports the following operating systems:. As well as this, you need to be logged into the PC as an administrator, and you should have access to a printer so that you can print the recovery key. To enable BitLocker, you start by heading to the start menu search box, and search for Manage BitLocker.
You may find this under Device Encryption, or as its own setting in the control panel. First, Windows will check your system settings and configuration to make sure that you can use BitLocker.

The second tool requires manually creating a Live CD with Ubuntu, compiling and installing Bitleaker according to the manual.
You will need to disable Secure Boot to run the tool. The alternative way would be signing the modified bootloader and kernel with your signature and adding the public key to BIOS; this, however, defies the purpose as it alters the content of PCR registers. It operates at the frequency of 33 MHz. For TPM 1. However, he found it to be far from perfect for sniffing TPM traffic as he had to solve synchronization problems and even patch the firmware.
Sniffing TPM 2. All he needed to do was soldering the pins, enabling the sniffer and obtaining the master key. Note that desktop motherboards with add-on TPM chips are even easier to sniff with no soldering required. Connecting to the TPM chip:. Despite the fact that the TPM chip itself does not do encryption, gaining access to the encryption key is not an easy task. I described a number of methods that can be used to extract the encryption keys from the TPM module.
Even if you never use any of them, they are certainly worth being part of your arsenal.
