A Trusted Platform Module (TPM) is a secure cryptoprocessor that implements the ISO/IEC 11889 standard. Common uses are verifying that the boot process starts from a trusted combination of hardware and software and storing disk encryption keys. A TPM 2.0 implementation is part of the Windows 11 system requirements. [1]
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 ...
The static chain of trust starts when the platform powers on (or the platform is reset), which resets all PCRs to their default value. For server platforms, the first measurement is made by hardware (i.e., the processor) to measure a digitally signed module (called an Authenticated Code Module or ACM) provided by the chipset manufacturer. The ...
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]
On January 30, 2001, version 1.0 of the Trusted Computing Platform Specifications was released [6] IBM was the first original equipment manufacturer to incorporate hardware features based on the specifications with the introduction of its ThinkPad T30 mobile computer in 2002.
The Open Mobile Terminal Platform (OMTP) first defined TEE in their "Advanced Trusted Environment:OMTP TR1" standard, defining it as a "set of hardware and software components providing facilities necessary to support applications," which had to meet the requirements of one of two defined security levels. The first security level, Profile 1 ...
