To utilize a TPM, the user needs a software library that communicates with the TPM and provides a friendlier API than the raw TPM communication. Currently, there are several such open-source TPM 2.0 libraries. Some of them also support TPM 1.2, but mostly TPM 1.2 chips are now deprecated and modern development is focused on TPM 2.0.

In current Trusted Computing specifications, there are two hardware components: the Trusted Platform Module (TPM), which will provide secure storage of cryptographic keys and a secure cryptographic co-processor, and a curtained memory feature in the CPU. In NGSCB, there are two software components, the Nexus, a security kernel that is part of ...
