Terminology for Post-Quantum Traditional Hybrid Schemes
RFC 9794, “Terminology for Post-Quantum Traditional Hybrid Schemes”, is an Informational document published in June 2025 by F. Driscoll, M. Parsons, B. Hale. The canonical text is published by the RFC Editor.
Abstract
One aspect of the transition to post-quantum algorithms in cryptographic protocols is the development of hybrid schemes that incorporate both post-quantum and traditional asymmetric algorithms. This document defines terminology for such schemes. It is intended to be used as a reference and, hopefully, to ensure consistency and clarity across different protocols, standards, and organisations.
