Scope:

ISO/IEC 10118 (all parts) specifies hash-functions and is therefore applicable to the provision of authentication, integrity and non-repudiation services. Hash-functions map strings of bits of variable (but usually upper bounded) length to fixed-length strings of bits, using a specified algorithm. They can be used for

— reducing a message to a short imprint for input to a digital signature mechanism, and
— committing the user to a given string of bits without revealing this string.

NOTE The hash-functions specified in ISO/IEC 10118 (all parts) do not involve the use of secret keys. However, these hash-functions may be used, in conjunction with secret keys, to build message authentication codes. Message Authentication Codes (MACs) provide data origin authentication as well as message integrity. Techniques for computing a MAC using a hash-function are specified in ISO/IEC 9797-2 [1].

This document contains definitions, symbols, abbreviations and requirements that are common to all the other parts of ISO/IEC 10118. The criteria used to select the algorithms specified in subsequent parts of ISO/IEC 10118 are defined in Annex B of this document.

Project need:

To review the Standard within the required 5 year period.

The system allows SCC-accredited Standards Development Organizations (SDOs), and members of the public, to be informed of new work in Canadian standards development, and allows SCC-accredited SDOs to identify and resolve potential duplication of standards and effort.

Individual SDOs are responsible for the content and accuracy of the information presented here. The text is presented in the language in which it was provided to SCC.
