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.
Intel Trusted Execution Technology (Intel TXT, formerly known as LaGrande Technology) is a computer hardware technology of which the primary goals are: Attestation of the authenticity of a platform and its operating system. Assuring that an authentic operating system starts in a trusted environment, which can then be considered trusted.
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 ...
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.
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
Direct Anonymous Attestation (DAA) is a cryptographic primitive which enables remote authentication of a trusted computer whilst preserving privacy of the platform's user. . The protocol has been adopted by the Trusted Computing Group (TCG) in the latest version of its Trusted Platform Module (TPM) specification [1] to address privacy concerns (see also Loss of Internet anonymi
the totality of protection mechanisms within it, including hardware, firmware, and software, the combination of which is responsible for enforcing a computer security policy. In other words, trusted computing base (TCB) is a combination of hardware, software, and controls that work together to form a trusted base to enforce your security policy.
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]
