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. The term can also refer to a chip conforming to the standard.
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.
One of Windows 11’s system requirements is TPM 2.0. Microsoft has stated that this is to help increase security against firmware and ransomware attacks.

Trusted Platform Module (TPM) technology is designed to provide hardware-based, security-related functions. A TPM chip is a secure crypto-processor that is designed to carry out cryptographic operations. The chip includes multiple physical security mechanisms to make it tamper-resistant, and malicious software is unable to tamper with the security functions of the TPM. Some of the key advantages of using TPM technology are that you can:
Generate, store, and limit the use of cryptographic keys.
Use TPM technology for platform device authentication by using the TPM’s unique RSA key, which is burned into it.
Help ensure platform integrity by taking and storing security measurements.
The most common TPM functions are used for system integrity measurements and for key creation and use. During the boot process of a system, the boot code that is loaded (including firmware and the operating system components) can be measured and recorded in the TPM. The integrity measurements can be used as evidence for how a system started and to make sure that a TPM-based key was used only when the correct software was used to boot the system.
