![]() 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 for the authentication of 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).Sealed storage: Specifies the TPM state for the data to be decrypted (unsealed).User-level RSA key containers are stored with the Windows user profile for a particular user and can be used to encrypt and decrypt information for applications that run under that specific user identity. Each TPM has a master wrapping key, called the storage root key, which is stored within the TPM itself. This process, often called wrapping or binding a key, can help protect the key from disclosure. Computers that incorporate a TPM can create cryptographic keys and encrypt them so that they can only be decrypted by the TPM. Binding: Data is encrypted using the TPM bind key, a unique RSA key descended from a storage key.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.The Trusted Platform Module (TPM) provides: 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 9 April 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 3 March 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 attacks. One of Windows 11's operating system requirements is TPM 2.0 implementation. The term can also refer to a chip conforming to the standard ISO/IEC 11889. Trusted Platform Module ( TPM) is an international standard for a secure cryptoprocessor, a dedicated microcontroller designed to secure hardware through integrated cryptographic keys.
