Requires random number generator, public-key cryptographic algorithm, cryptographic hash function, mask generation function, digital signature generation and verification, and Direct Anonymous Attestation, as well as key generation. SHA-1 and SHA-256 required, and vendors are free to add new algorithms using TCG IDs. The following are more detailed differences of TPM 2.0 compared to 1.2. So as stated in the system requirement list, TPM 2.0 must be supported and enabled on this PC for Windows 11 update. It can now not only serve to accelerate facial recognition, fingerprint recognition, disk encryption, but also be used to defend against the current popular ransomware virus and even sophisticated hacking attacks.
At that time, the main role of the TPM was to verify the integrity of the system when Windows was booted, as well as to store the key files needed for security functions.īut while the previous version of TPM (TPM 1.2) was as old as 2011, TPM 2.0 is the latest version. Compared with its predecessor, it has significantly increased the variety and security of the module's built-in encryption algorithms, with more compatible software and scenarios.Īccording to David Weston, the TPM module has been given more functions in Windows 11. And since TPM uses a completely dedicated circuit, the whole process of calculating and storing can be done without going through the memory and leaving traces in the hard disk, so the security of key generation, verification and storage is very high.īack in the Windows 8 era, there was already a demand for TPM chips in computers. TPM itself is also a piece of encryption storage unit in the computer, which can not only calculate the key, but also store the key. These passwords can be encryption locks for hard disks, feature codes used by operating systems to verify their integrity (to check if programs have been tampered with), or activation codes for specialized software. That is, the generation or verification of passwords in the computer using its built-in encryption algorithms. TPM has a wide range of roles as a hardware security key, such as device identification, authentication, encryption and integrity verification. For now, the latest version of TPM is 2.0. TPM (Trusted Platform Module) is an international standard for a secure processor, and a specialized microcontroller to protect hardware with an integrated cryptographic key. How to install Windows 11 without TPM 2.0.How to check TPM 2.0 status on your computer.Here you will learn more about what TPM is, and how to check and enable TPM 2.0 for Windows 11 update. If it does not meet the criteria, then you will need to enable or upgrade your TPM.
You can check TPM status before doing the upgrade.
One of the requirements for Windows 11 update is that your PC supports TPM 2.0.
