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 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. The ...
TCG's most successful effort was the development of a Trusted Platform Module (TPM), a semiconductor intellectual property core or integrated circuit that conforms to the specification to enable trusted computing features in computers and mobile devices.
However, it is still possible to manually upgrade using an ISO image (as Windows 10 users on those processors will not be offered to upgrade to Windows 11 via Windows Update), or perform a clean installation as long as the system has Trusted Platform Module (TPM) 2.0 enabled, [48] but the user must accept that they will not be entitled to ...
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.
[289] [290] In addition, an enthusiast-created modification was released that disabled the check and allowed Windows 8.1 and earlier versions to continue to work on the platform. [291] Windows 10 versions 1703 and later do not support Intel Clover Trail system-on-chips, per Microsoft's stated policy of only providing updates for devices during ...
In current Trusted Computing specifications, there are two hardware components: the Trusted Platform Module (TPM), which will provide secure storage of cryptographic keys and a secure cryptographic co-processor, and a curtained memory feature in the CPU. In NGSCB, there are two software components, the Nexus, a security kernel that is part of ...
While device encryption is offered on all editions of Windows 8.1, unlike BitLocker, device encryption requires that the device meet the InstantGo (formerly Connected Standby) specifications, [23] which requires solid-state drives and a TPM 2.0 chip. [21] [24] Starting with Windows 10 1703, the requirements for device encryption have changed ...
