Full title and description

ISO/IEC 10118-4:1998/Cor 1:2014 — Information technology — Security techniques — Hash-functions — Part 4: Hash-functions using modular arithmetic — Technical Corrigendum 1. This corrigendum publishes technical and editorial corrections that apply to the original ISO/IEC 10118-4:1998 text, which specifies the MASH family of modular-arithmetic-based hash functions.

Abstract

This Technical Corrigendum (Cor 1:2014) issues corrections and clarifications to ISO/IEC 10118-4:1998, the part of the ISO/IEC 10118 series that defines hash-functions using modular arithmetic (notably the MASH-1 and MASH-2 constructions). The corrigendum is brief (2 pages) and is intended to correct errors and improve the precision of normative text without changing the substantive algorithmic intent of the original standard.

• ICS / categories: 35.030 (IT security).
• Edition / version: Edition 1 (Technical Corrigendum 1 to the 1998 edition).
• Number of pages: 2 (corrigendum document).

Scope

This corrigendum applies specifically to ISO/IEC 10118-4:1998 — the part of the ISO/IEC 10118 series that specifies hash functions using modular arithmetic (MASH-1 and MASH-2). It corrects and clarifies elements of the original 1998 text; it does not constitute a full revision or replacement of the base standard.

Key topics and requirements

• Corrections and editorial clarifications to normative clauses of ISO/IEC 10118-4:1998.
• Adjustments intended to ensure correct interpretation and implementation of the MASH-1 and MASH-2 hash-function descriptions.
• Alignment of notation, parameters, and normative references where minor errors or ambiguities were identified.
• Issued as a short (2-page) corrigendum rather than a substantive amendment; major functional changes are not introduced by this corrigendum.

Typical use and users

Implementers of cryptographic libraries, system architects who rely on hash functions for signatures or identification schemes, standards developers, and evaluators reviewing conformance to ISO/IEC 10118-4:1998. The corrigendum is primarily relevant to those implementing or validating the modular-arithmetic hash functions (MASH-1 and MASH-2) defined in the original standard.

Related standards

Related items include the base standard ISO/IEC 10118-4:1998 (the part to which this corrigendum applies), the separate Amendment ISO/IEC 10118-4:1998/Amd 1:2014 (Object identifiers), and other parts of the ISO/IEC 10118 series that cover different hash-function families (parts 1–5). The corrigendum and the amendment were both published in 2014 to update and correct the 1998 edition.

FAQ

Q: What is this standard?

A: It is Technical Corrigendum 1 (Cor 1:2014) to ISO/IEC 10118-4:1998, publishing technical and editorial corrections for the part of ISO/IEC 10118 that specifies hash-functions using modular arithmetic.

Q: What does it cover?

A: The corrigendum corrects and clarifies elements of the 1998 text for ISO/IEC 10118-4 (which defines the MASH-1 and MASH-2 modular-arithmetic hash functions); it is two pages long and intended to fix errors/ambiguities rather than change algorithmic intent.

Q: Who typically uses it?

A: Cryptographic library implementers, security engineers, standards committees, certification and conformance testers, and anyone maintaining implementations or documentation that reference ISO/IEC 10118-4.

Q: Is it current or superseded?

A: The corrigendum (published July 2014) is the published correction to the 1998 edition; it remains the applicable corrigendum for ISO/IEC 10118-4:1998. The base standard itself has been subject to review/confirmation cycles; users should check the ISO catalogue for the latest status of the base standard and any further amendments.

Q: Is it part of a series?

A: Yes — ISO/IEC 10118 is a multi-part series specifying different hash-function families (parts 1–5). This corrigendum applies only to Part 4 (modular arithmetic). Related corrigenda and amendments for the part are listed separately by ISO.

Q: What are the key keywords?

A: Hash-function, modular arithmetic, MASH-1, MASH-2, corrigendum, ISO/IEC 10118-4, IT security, ISO/IEC JTC 1/SC 27.
