Overview
ISO/IEC 10118-4:1998/Amd 1:2014 is an important amendment to the international standard ISO/IEC 10118-4:1998, focusing on information technology security techniques related to hash-functions using modular arithmetic. This amendment introduces object identifiers (OIDs) specific to the hash-functions defined in Part 4 of the ISO/IEC 10118 series, enabling standardized and unambiguous referencing of these cryptographic algorithms in security applications and protocols.
Published by ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission), the document reflects global consensus and technical rigor in the field of cryptographic hash functions. It complements existing standards by enhancing identification mechanisms required for secure communications and cryptographic interoperability.
Key Topics
- Hash-functions using modular arithmetic: Part 4 of ISO/IEC 10118 outlines hash functions that leverage modular arithmetic principles for secure hashing operations.
