We propose FO_ AKE, a generic construction of two-message authenticated key exchange
(AKE) from any passively secure public key encryption (PKE) in the quantum random oracle …

Quantum information has the property that measurement is an inherently destructive
process. This feature is most apparent in the principle of complementarity, which states that …

Sponge hashing is a widely used class of cryptographic hash algorithms which underlies the
current international hash function standard SHA-3. In a nutshell, a sponge function takes as …

The learning-with-errors (LWE) problem is one of the fundamental problems in
computational learning theory and has in the last years become the cornerstone of …

Many post-quantum cryptosystems which have been proposed in the National Institute of
Standards and Technology (NIST) standardization process follow the same meta-algorithm …

Fundamental principles of quantum mechanics have inspired many new research directions,
particularly in quantum cryptography. One such principle is quantum no-cloning which has …

Function inversion is the problem that given a random function $ f:[M]\to [N] $, we want to find
pre-image of any image $ f^{-1}(y) $ in time $ T $. In this work, we revisit this problem under …

Safeguarding current and future IT security from quantum computers implies more than the
mere development of Post-Quantum Cryptography (PQC) algorithms. Much work in this …

Signing quantum messages has long been considered impossible even under
computational assumptions. In this work, we challenge this notion and provide three …

Research on the security of lattice-based public-key encryption schemes against misuse
attacks is an important part of the cryptographic assessment of the National Institute of …
