ISO/IEC 11889-4 (2009-05)

ISO/IEC 11889 defines the Trusted Platform Module (TPM), a device that enables trust in computing platforms in general. ISO/IEC 11889-4:2009 defines the commands, actions of the commands, and the parameters to the commands that provide the TPM functionality.
This standard has been revised by ISO/IEC 11889-4:2015. However, the 2009 Edition remains available through 2025 to permit stakeholders to complete technical work tailoring their adoption of the 2015 Edition to meet their security and privacy objectives.
