ISO/IEC 9798-4:1999/COR2:2012

ISO/IEC 9798-4:1999/COR2:2012 is a supporting corrigendum to the entity authentication reference Information technology - Security techniques - Entity authentication - Part 4: Mechanisms using a cryptographic check function - Technical Corrigendum 2. It is relevant for organizations that rely on cryptographic authentication methods and need to align engineering documentation, verification activities, and compliance review with the corrected text. For teams working through technical assessment, procurement review, or conformity assessment preparation, ISO/IEC 9798-4:1999/COR2:2012 helps ensure the parent document is applied consistently and accurately.

Overview of ISO/IEC 9798-4:1999/COR2:2012

This corrigendum is connected to the ISO/IEC 9798 series and should be used as a modifying reference to the parent part rather than as a standalone technical specification. Its purpose is to correct or clarify the published text for entity authentication mechanisms that use a cryptographic check function. In practice, that makes it useful during technical review, documented evaluation, and control of security-related engineering documentation where precise interpretation of the parent document is important.

Compliance applications of ISO/IEC 9798-4:1999/COR2:2012

Organizations may use ISO/IEC 9798-4:1999/COR2:2012 when maintaining specifications, validation records, and test plans for systems that implement cryptographic entity authentication. It can support compliance workflows in product development, laboratory evaluation, and security assurance activities where the corrected wording of the parent document matters. The corrigendum is also relevant for procurement teams and auditors that need a reliable technical reference when checking whether internal requirements, supplier documentation, or assessment criteria reflect the intended authentication mechanism.

Importance of compliance with ISO/IEC 9798-4:1999/COR2:2012

Using the corrigendum alongside the parent document helps reduce interpretation errors and improves operational consistency across engineering and quality workflows. For security mechanisms, even small textual corrections can affect testing consistency, implementation review, and conformity assessment preparation. Referencing ISO/IEC 9798-4:1999/COR2:2012 supports more accurate technical validation, better risk management, and clearer procurement decisions when authentication behavior must be documented and verified with confidence.

• Supporting corrigendum linked to the ISO/IEC 9798 entity authentication series
• Relevant to cryptographic check function-based authentication requirements
• Useful for technical review, validation records, and compliance workflows
• Helps maintain alignment between the parent document and implementation documentation
