CSA Preface

Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).

For brevity, this Standard will be referred to as "CAN/CSA-ISO/IEC 11889-3" throughout.

At the time of publication, ISO/IEC 11889-3:2015 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC.

Scope

This part of ISO/IEC 11889 contains the definitions of the Trusted Platform Module (TPM) commands. These commands make use of the constants, flags, structures, and union definitions defined in ISO/IEC 11889-2.

The detailed description of the operation of the commands is written in the C language with extensive comments. The behavior of the C code in this part of ISO/IEC 11889 is normative but does not fully describe the behavior of a TPM. The combination of this part of ISO/IEC 11889 and ISO/IEC 11889-4 is sufficient to fully describe the required behavior of a TPM.

The code this part of ISO/IEC 11889 and ISO/IEC 11889-4 is written to define the behavior of a compliant TPM. In some cases it is not possible to provide a compliant implementation. In those cases, any implementation provided by the vendor that meets the general description of the function provided in this part of ISO/IEC 11889 would be compliant.

EXAMPLE Firmware update is a case where it is not possible to provide a compliant implementation.

The code in thie part of ISO/IEC 11889 and ISO/IEC 11889-4 is not written to meet any particular level of conformance nor does this specification require that a TPM meet any particular level of conformance.
