Several Password Authenticated Key Exchange (PAKE) protocols have been recently proposed that leverage a Key-Encapsulation Mechanism (KEM) to create an efficient and easy-to-implement post-quantum secure PAKE. This line of work is driven by the intention of the National Institute of Standards and Technology (NIST) to soon standardize a lattice-based post-quantum KEM called $\mathsf{Kyber}$. In two recent works, Beguinet et …
