Paper 2023/1811 , Eindhoven University of Technology , Technical University of Denmark The Fujisaki-Okamoto (FO) transformation is used in most proposals for post-quantum secure key encapsulation mechanisms (KEMs) like, e.g., Kyber [BDK+18]. The security analysis of FO in the presence of quantum attackers has made huge progress over the last years.

Paper 2023/1368 , Hochschule Darmstadt , Eindhoven University of Technology , Eindhoven University of Technology , Eindhoven University of Technology , Hochschule Darmstadt We revisit OCAKE (ACNS 23), a generic recipe that constructs password-based authenticated key exchange (PAKE) from key encapsulation mechanisms (KEMs) in a black-box way. This allows to potentially achieve post-quantum security by instantiating the KEM with a post-quantum KEM like KYBER.
