The software in charge of hashing the setup determines the extent of the summary. One could use the hash to verify that the hardware and software have not been changed. Remote attestation: Creates a nearly unforgeable hash key summary of the hardware and software configuration.Facilities for the secure generation of cryptographic keys for limited uses.Part 4 – Supporting Routines (added in TPM 2.0).Part 1 – Architecture (renamed from Design Principles).Each part consists of a document that makes up the whole of the new TPM specification. When a new revision is released it is divided into multiple parts by the Trusted Computing Group. The group continues work on the standard incorporating errata, algorithmic additions and new commands, with its most recent edition published as 2.0 in November 2019. On Apthe Trusted Computing Group announced a major upgrade to their specification entitled TPM Library Specification 2.0. TPM Main Specification Version 1.2 was finalized on March 3, 2011, completing its revision. It evolved into TPM Main Specification Version 1.2 which was standardized by International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC) in 2009 as ISO/IEC 11889:2009. Trusted Platform Module (TPM) was conceived by a computer industry consortium called Trusted Computing Group (TCG). Microsoft has stated that this is to help increase security against firmware and ransomware attacks.

One of Windows 11's system requirements is TPM 2.0. TPM is used for digital rights management (DRM), Windows Defender, Windows Domain logon, protection and enforcement of software licenses, and prevention of cheating in online games. The term can also refer to a chip conforming to the standard. Trusted Platform Module ( TPM, also known as ISO/IEC 11889) is an international standard for a secure cryptoprocessor, a dedicated microcontroller designed to secure hardware through integrated cryptographic keys.
