PCs of the future need this modern hardware root-of-trust to help protect from both common and sophisticated attacks like ransomware and more sophisticated attacks from nation-states. TPM is designed to protect PCs better against advanced forms of attacks, according to Microsoft. Microsoft decided to raise the security baseline of the Windows 11 operating system by making TPM 2.0 a mandatory system requirement. Why does Windows 11 require a TPM 2.0 chip? to help protect encryption keys, user credentials, and other sensitive data behind a hardware barrier so that malware and attackers can’t access or tamper with that data. Microsoft Director of Enterprise and OS Security, David Weston, described the main function of the TPM chip in the following way: TPM can check the integrity of the system during the boot process to make sure it has not been tampered with. It is designed to be tamper-resistant, and includes a unique key that may be used for platform device authentication. The TPM chip is a secure crypto-processor that is designed for cryptographic operations. It may be used by the operating system to better protect devices against advanced threats.Ī TPM device is therefore any device with a TPM chip. It comes in the form of a chip on the computer's motherboard or as part of the processor, and serves a number of purposes, including device authentication, encryption, identification and integrity verification.
