Trusted Platform Module (TPM) is an international standard for a secure cryptoprocessor, a dedicated microcontroller designed to secure hardware through integrated cryptographic keys. The term can also refer to a chip conforming to the standard ISO/IEC 11889.
PCR values are available both locally and remotely. 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.
In October 2017, it was reported that a flaw enabled private keys to be inferred from public keys, which could allow an attacker to bypass BitLocker encryption when an affected TPM chip is used. [63] The flaw is the Return of Coppersmith's Attack or ROCA vulnerability which is in a code library developed by Infineon and had been in widespread ...
This key is used to allow the execution of secure transactions: every Trusted Platform Module (TPM) is required to be able to sign a random number (in order to allow the owner to show that he has a genuine trusted computer), using a particular protocol created by the Trusted Computing Group (the direct anonymous attestation protocol) in order ...
Version 24H2 introduces modified system requirements, for some systems, for the first time since the release of Windows 11, as follows: A x86-64-v2 CPU supporting SSE4.2 and POPCNT CPU instructions is now required, otherwise the Windows kernel is unbootable. [9]
FIDO supports a full range of authentication technologies, including biometrics such as fingerprint and iris scanners, voice and facial recognition, as well as existing solutions and communications standards, such as Trusted Platform Modules (TPM), USB security tokens, embedded Secure Elements (eSE), smart cards, and near-field communication ...
The PSP is an integral part of the boot process, without which the x86 cores would never be activated. On-chip phase Firmware located directly on the PSP chip sets up the ARM CPU, verifies the integrity of the SPI ROM, using various data structures locates the off-chip firmware (AGESA) from the SPI ROM, and copies it over to internal PSP memory.
As part of the minimum system requirements, Windows 11 only runs on devices with a Trusted Platform Module 2.0 security coprocessor, [128] [129] albeit with some exceptions, see § System requirements for details. According to Microsoft, the TPM 2.0 coprocessor is a "critical building block" for protection against firmware and
