TPM Library Specification

Date Published: October, 01, 2014

TCG has released the TPM 2.0 library specification that provides updates to the previous published TPM main specifications.

The changes and enhancements compared to the existing TPM 1.2 include:

  • Support for additional cryptographic algorithms
  • Enhancements to the availability of the TPM to applications
  • Enhanced authorization mechanisms
  • Simplified TPM management
  • Additional capabilities to enhance the security of platform services

Other, future TCG specifications will detail how the TPM can be implemented in various platforms through TCG platform specific specifications. These future specifications include the TPM Software Stack specification (TSS) and separate specifications for PCs, mobile, embedded and virtualized platforms.

TPM 2.0 FAQ

Q. What will this specification be used for?

  1. The TPM 2.0 specification is a “library specification”, which means that it supports a wide variety of functions, algorithms and capabilities upon which future platform-specific specifications will be based. Basically, it is the core capabilities and commands of the TPM. The TPM 2.0 specification will be used as the basis for creation of TPM specifications for different platforms.
