ECC-based Direct Anonymous Attestation using the Barreto–Naehrig 256-bit curve is optional for the TCG PC Client Platform TPM Profile (PTP) Specification. [18] The TPM 2.0 common library specification also requires key generation and key derivation functions. [22] Hierarchy One (storage) Three (platform, storage and endorsement) Root keys
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 ...
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.
VBE is made available through the video card's BIOS, which installs some interrupt vectors that point to itself during boot up. Most newer cards implement the more capable VBE 3.0 standard. Older versions of VBE provide only a real mode interface, which cannot be used without a significant performance penalty from within protected mode ...
Original equipment manufacturers (OEM) can still ship computers without TPM 2.0 enabled upon Microsoft's approval. [128] [160] On May 20, 2024, Microsoft announced "Copilot+ PC"—a brand of Windows 11 devices that are designed to support enhanced artificial intelligence features.
BitLocker originated as a part of Microsoft's Next-Generation Secure Computing Base architecture in 2004 as a feature tentatively codenamed "Cornerstone" [4] [5] and was designed to protect information on devices, particularly if a device was lost or stolen.
