To address this, protocols and infrastructure must transition to post-quantum algorithms, which are designed to resist both traditional and quantum attacks. This document explains why engineers need to be aware of and understand post-quantum cryptography (PQC), and it details the impact of CRQCs on existing systems and the challenges involved in transitioning to post-quantum algorithms. Unlike previous cryptographic updates, this shift may require significant protocol redesign due to the unique properties of post-quantum algorithms.", "pub_date": "June 2026", "keywords": [ "PQC" ], "obsoletes": [], "obsoleted_by": [], "updates": [], "updated_by": [], "see_also": [], "doi": "10.17487/RFC9958", "errata_url": "https://www.rfc-editor.org/errata/rfc9958" }
