This hybrid scheme for confidentiality serves as a transitional approach, paving the path for a future migration to PQC KEM algorithms. For more details, refer to https://datatracker.ietf.org/doc/html/draft-ietf-pquip-pqc-engineers-03#section-14. Other protocols like IPSEC are also discussing the use of PQC KEM algorithms. -Tiru > > Are there critical use cases that multiple vendors need to support that > only work without using HPKE? > > OS > > On Tue, Mar 5, 2024, 5:34 AM tirumal reddy <kondtir@gmail.com> wrote: > >> We have published a new draft >> https://www.ietf.org/archive/id/draft-reddy-cose-jose-pqc-kem-00.html, >> that describes the conventions for using Post-Quantum Key Encapsulation >> Mechanisms (PQ-KEMs) within JOSE and COSE.
