The primary scope of TPM is to ensure the integrity of a platform. Security embedded in hardware provides more protection than a software-only solution.

Ĭomputer programs can use a TPM to authenticate hardware devices, since each TPM chip has a unique and secret Endorsement Key (EK) burned in as it is produced. Other Trusted Computing functions for the data to be decrypted (unsealed).

Sealing: Similar to binding, but in addition, specifies the TPM state for the data to be decrypted (unsealed).

Binding: Encrypts data using the TPM bind key, a unique RSA key descended from a storage key.

This allows a third party to verify that the software has not been changed. The software in charge of hashing the configuration data determines the extent of the summary.

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 April 9th, 2014 the 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. Trusted Platform Module (TPM) was conceived by a computer industry consortium called Trusted Computing Group (TCG), 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. 7.1 2017 weak key generation controversy.
