ISO/IEC 10118-4:1998

ISO/IEC 10118-4:1998 defines part of the Information technology - Security techniques - Hash-functions series, with a specific focus on hash-functions using modular arithmetic. For engineering, testing, and procurement teams, it serves as a technical reference when evaluating whether a hash-function approach aligns with a security architecture, documented evaluation process, or conformity assessment need. Because it is part of the broader ISO/IEC 10118 family, ISO/IEC 10118-4:1998 is most useful when a project requires consistent security documentation and a clear basis for technical review.

Overview of ISO/IEC 10118-4:1998

This document addresses hash-functions implemented through modular arithmetic, which places it within the mathematical and security-oriented side of information technology. As a derived document in the ISO/IEC 10118 series, it supports a parent reference rather than functioning as an isolated topic area. Organizations may use it during technical assessment, design review, or validation of security-related functions where formal documentation is needed. It is especially relevant when teams want a precise compliance reference for comparing implementation choices and recording engineering decisions.

Compliance applications of ISO/IEC 10118-4:1998

ISO/IEC 10118-4:1998 may be used in workflows involving security design review, verification activities, and product evaluation for systems that rely on hash-functions. Typical use cases include internal engineering documentation, laboratory evaluation, procurement checks, and preparation for conformity assessment where a documented security technique must be referenced. It can also support technical validation in environments that require traceable cryptographic design choices, operational consistency, and a defensible basis for risk management and regulatory preparation.

Importance of compliance with ISO/IEC 10118-4:1998

Using ISO/IEC 10118-4:1998 as a reference can help teams maintain consistency in security-related engineering documentation and testing workflows. It supports clearer technical review, reduces ambiguity during procurement or design qualification, and helps align implementation discussions with an established compliance reference. For organizations preparing technical files, conformity assessment evidence, or validation records, the document can contribute to quality assurance and risk reduction by giving reviewers a common basis for evaluating hash-function design decisions.

• Supports review of hash-functions based on modular arithmetic within the ISO/IEC 10118 series
• Useful for engineering documentation, verification planning, and security-focused technical assessment
• Helps teams maintain traceability during compliance workflows and conformity assessment preparation
• Relevant to procurement and laboratory evaluation where a documented security technique is required
