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]
The Microsoft products Windows Vista, Windows 7, Windows 8 and Windows RT make use of a Trusted Platform Module to facilitate BitLocker Drive Encryption. [22] Other known applications with runtime encryption and the use of secure enclaves include the Signal messenger [23] and the e-prescription service ("E-Rezept") [24] by the German government.
The static chain of trust starts when the platform powers on (or the platform is reset), which resets all PCRs to their default value. For server platforms, the first measurement is made by hardware (i.e., the processor) to measure a digitally signed module (called an Authenticated Code Module or ACM) provided by the chipset manufacturer.
Although the TPM can only store a single cryptographic key securely, secure storage of arbitrary data is by extension possible by encrypting the data such that it may only be decrypted using the securely stored key. The TPM is also able to produce a cryptographic signature based on its hidden key. This signature may be verified by the user or ...
When used in conjunction with a compatible Trusted Platform Module (TPM), BitLocker can validate the integrity of boot and system files before decrypting a protected volume; an unsuccessful validation will prohibit access to a protected system. [6] [7] BitLocker was briefly called Secure Startup before Windows Vista's release to manufacturing. [6]
In Windows, if Secure Boot is enabled, all kernel drivers must be digitally signed; non-WHQL drivers may be refused to load. In February 2013, another Red Hat developer attempted to submit a patch to the Linux kernel that would allow it to parse Microsoft's authenticode signing using a master X.509 key embedded in PE files signed by Microsoft.
[6] [7] [8] Because PSP is the chip that decides whenever the x86 cores will run or not [citation needed], it is used to implement hardware downcoring, specific cores on the system can be made permanently inaccessible during manufacturing. The PSP also provides a random number generator for the RDRAND instruction [9] and provides TPM services.
Skylake is the last Intel platform on which Windows earlier than Windows 10 are officially supported by Microsoft, [11] although enthusiast-created modifications are available that disabled the Windows Update check and allowed Windows 8.1 and earlier to continue to receive Windows Updates on this and later platforms.
