It’s exciting to see post-quantum cryptography applied to more advanced cryptographic primitives and protocols such as Privacy Pass. While the NIST PQC standardization effort focuses on cryptographic primitives, these primitives will eventually have to be used in protocols. Several protocol updates were presented at RWPQC and RWC using this approach, starting with a post-quantum variant of the Noise protocol framework (video, slides) for constructing key exchange protocols.
