This part of ISO/IEC 11889 defines the architectural elements of the Trusted Platform Module (TPM), adevice which enables trust in computing platforms in general. Some TPM concepts are explainedadequately in the context of the TPM itself. Other TPM concepts are explained in the context of how aTPM helps establish trust in a computing platform. When describing how a TPM helps establish trust in acomputing platform, this part of ISO/IEC 11889 provides some guidance for platform requirements.However, the scope of ISO/IEC 11889 is limited to TPM requirements.This part of ISO/IEC 11889 illustrates TPM security and privacy techniques in the context of a platformthrough the use of cryptography. It includes definitions of how different cryptographic techniques areimplemented by a TPM. The scope of ISO/IEC 11889 does not include cryptographic analysis orguidance about the applicability of different algorithms for specific uses cases.TPM requirements in this part of ISO/IEC 11889 are general, covering concepts like integrity protection,isolation and confidentially. Defining a specific strength of function or assurance level is out of scope forISO/IEC 11889. This approach limits the guarantees provided by ISO/IEC 11889 itself, but it does allowthe TPM architectural elements defined to be adapted to meet diverse implementation and platformspecific needs.
