Two ways to verify whether TPM 2.0 is setup without specific software: Linux has support for TPM 2.0 since version 3.20 and should not require any other steps to be enabled on a default Arch install. Many informative resources to learn how to configure and make use of TPM 2.0 services in daily applications are available from the tpm2-software community.Ī TPM 2.0 chip has been a requirement for computers certified to run Windows 10 since. (Discuss in Talk:Trusted Platform Module) You can help by expanding it with information on how to set up and use a TPM 2.0 device. Some TPM chips can be switched between 2.0 and 1.2 through a firmware upgrade (which can be done only a limited number of times). TPM 2.0 requires UEFI boot BIOS or Legacy boot systems can only use TPM 1.2. All software access the TPM through the tcsd daemon. TPM 1.2 uses the 'TrouSerS' TSS (TCG software stack) by IBM, which is packaged as trousers AUR ( tcsd) and tpm-tools AUR (userspace).

There are two choices of userspace tools, tpm2-tools by Intel and ibm-tss AUR by IBM. According to a systemd project member, using tpm2-abrmd is no longer recommended. TPM 2.0 allows direct access via /dev/tpm0 (one client at a time), kernel-managed access via /dev/tpmrm0, or managed access through the tpm2-abrmd resource manager daemon.There are two very different TPM specifications: 2.0 and 1.2, which also use different software stacks. If your hardware has TPM support but it is not showing up, it might need to be enabled in the BIOS settings. TPM is naturally supported only on devices that have TPM hardware support. In practice a TPM can be used for various different security applications such as secure boot, key storage and random number generation. Trusted Platform Module (TPM) is an international standard for a secure cryptoprocessor, which is a dedicated microprocessor designed to secure hardware by integrating cryptographic keys into devices. PCR registers sealing and using in combination with LUKS. Reason: Needs clarification about usage difference between TPM 1.2 and 2.0, Evil Maid attack defense and Trusted boot.
