TPM
Definition
Trusted Platform Module, a protected cryptographic and measurement component.
Detailed explanation
TPM means Trusted Platform Module, a hardware or firmware-backed security component for protected keys, measurements, and cryptographic operations. Windows uses TPM capabilities for features such as BitLocker, measured boot, and Windows Hello. A TPM establishes a hardware root of trust but does not replace user authentication. Platform Configuration Registers accumulate measurements so later software can evaluate boot history, and sealed keys can be released only under defined states. TPM 2.0 standardizes algorithms and command structures, while discrete, integrated, and firmware TPM implementations provide the interface through different hardware paths.
