Note that this mode requires that the BIOS on the protected machine supports the reading of USB devices in the pre-OS environment. BitLocker does not support smart cards for pre-boot authentication. [30] The following combinations of the above authentication mechanisms are supported, all with an optional escrow recovery key: TPM only [31] TPM ...
For mobile devices that can be stolen and attackers gain permanent physical access (paragraph Attacker with skill and lengthy physical access) Microsoft advise the use of pre-boot authentication and to disable standby power management. Pre-boot authentication can be performed with TPM with PIN protector or any 3rd party FDA vendor.
CPU/chipset/BIOS support for S0ix "Low Power S0 Idle" power state; 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 ...
Windows 8 and later have native support for TPM 2.0. Windows 7 can install an official patch to add TPM 2.0 support. [93] Windows Vista through Windows 10 have native support for TPM 1.2. The Trusted Platform Module 2.0 (TPM 2.0) has been supported by the Linux kernel since version 3.20 (2012) [94] [95] [96]
Trusted Platform Module: Whether the implementation can use a TPM cryptoprocessor. Filesystems : What filesystems are supported. Two-factor authentication : Whether optional security tokens ( hardware security modules , such as Aladdin eToken and smart cards ) are supported (for example using PKCS#11 )
Furthermore, the TPM has the capability to digitally sign the PCR values (i.e., a PCR Quote) so that any entity can verify that the measurements come from, and are protected by, a TPM, thus enabling Remote Attestation to detect tampering, corruption, and malicious software.
First, the block device is encrypted using a master key. This master key is encrypted with each active user key. [6] User keys are derived from passphrases, FIDO2 security keys, TPMs or smart cards. [7] [8] The multi-layer approach allows users to change their passphrase without re-encrypting the whole block device. Key slots can contain ...
The TPM can impose a limit on decryption attempts per unit time, making brute-forcing harder. The TPM itself is intended to be impossible to duplicate, so that the brute-force limit is not trivially bypassed. [5] Although this has the advantage that the disk cannot be removed from the device, it might create a single point of failure in the ...
