For example, a risk exists where attackers can compromise an operating system to access objects in memory. TPM can also achieve certain things using hardware that software simply cannot achieve. Originally, Windows 11 had a ‘hard floor’ requirement of TPM 1.2, but Microsoft subsequently decided to use TPM 2.0. With the move to TPM 2.0 in 2014, the algorithms ceased to be defined in the standard, so manufacturers could introduce new ones to improve security without revising the standard. ![]() The TPM specification, managed by the Trusted Computing Group (TCG), has matured over time to protect against vulnerabilities and follow trends in acceptable security practices.įor example, evidence emerged that the SHA-1 hashing algorithm of TPM 1.2 might be vulnerable in proof-of-concept attacks. Using dedicated (‘discrete’) or integrated hardware, Trusted Platform Modules have, since 2003, guarded cryptographic secrets. Now eight months after the Windows 11 announcement and five months removed from its general release, this article outlines the benefits of TPM and examines to what extent the requirement will protect devices from the most common threats. Interest in why Microsoft wants PCs to have TPM 2.0 immediately skyrocketed: Figure 1: Google search trends for TPM following Windows 11 requirements announcement. ![]() In contrast to the requirements of Windows 10, Windows 11 has a notable security hardware requirement: to install Windows 11, PC configurations must include version 2.0 of the Trusted Platform Module (TPM). In June of 2021, Microsoft announced the requirements for Windows 11.
