Information technology — Open systems interconnection directory — Part 11: Protocol specifications for secure operations

Apstrakt

This document provides guidance on how to prepare new and old protocols for cryptographic algorithm migration and defines auxiliary cryptographic algorithms to be used for migration purposes.
This document specifies a general wrapper protocol that provides authentication, integrity and confidentiality (encryption) protection for other protocols. This wrapper protocol includes a migration path for cryptographic algorithms allowing for smooth migration to stronger cryptographic algorithms as such requirements evolve. This will allow migration to quantum-safe cryptographic algorithms. Protected protocols can then be developed without taking security and cryptographic algorithms into consideration.
This document also includes some protocols to be protected by the wrapper protocol primarily for support of public-key infrastructure (PKI). Other specifications, e.g., Recommendations or International Standards, may also develop protocols designed to be protected by the wrapper protocol.
