Scope:

ISO/IEC 10118 specifies hash-functions and is therefore applicable to the provision of authentication, integrity and non-repudiation services. Hash-functions map arbitrary strings of bits to a 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 this part of ISO/IEC 10118 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. For the calculation of a MAC the user is referred to ISO/IEC 9797. This part of ISO/IEC 10118 contains definitions, symbols, abbreviations and requirements, that are common to all the other parts of ISO/IEC 10118.

Note: The information provided above was obtained by the Standards Council of Canada (SCC) and is provided as part of a centralized, transparent notification system for new standards development. 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.
