A Trusted Platform Module (TPM) is a secure cryptoprocessor that implements the ISO/IEC 11889 standard. Common uses are verifying that the boot process starts from a trusted combination of hardware and software and storing disk encryption keys. A TPM 2.0 implementation is part of the Windows 11 system requirements. [1]
[8] [14] NGSCB has yet to fully materialize; however, aspects of it are available in features such as BitLocker of Windows Vista, Measured Boot and UEFI of Windows 8, [15] Certificate Attestation of Windows 8.1, [16] Device Guard of Windows 10. [17] and Device Encryption in Windows 11 Home editions, with TPM 2.0 mandatory for installation.
Pre-boot authentication can be performed with TPM with PIN protector or any 3rd party FDA vendor. Best security is offered by offloading the cryptographic encryption keys from the protected client and supplying key material externally within the user authentication process. This method eliminates attacks on any built-in authentication method ...
Starting with Windows 10 1703, the requirements for device encryption have changed, requiring a TPM 1.2 or 2.0 module with PCR 7 support, UEFI Secure Boot, and that the device meets Modern Standby requirements or HSTI validation. [25]
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 )
When Secure Boot is enabled, it is initially placed in "setup" mode, which allows a public key known as the "platform key" (PK) to be written to the firmware. Once the key is written, Secure Boot enters "User" mode, where only UEFI drivers and OS boot loaders signed with the platform key can be loaded by the firmware.
Bootloader unlocking is the process of disabling the bootloader security that makes secure boot possible. It can make advanced customizations possible, such as installing custom firmware. On smartphones, this can be a custom Android distribution or another mobile operating system. Some bootloaders are not locked at all and some are locked, but ...
Windows 11, version 24H2, also known as the Windows 11 2024 Update [1] and codenamed Hudson Valley [2] [3] [4] is the third and current major update to Microsoft's Windows 11 operating system. It carries the build number 10.0.26100.
