Failing gracefully: Decryption failures and the Fujisaki-Okamoto transform
Kathrin Hövelmanns, Andreas Hülsing, Christian Majenz
In known security reductions for the Fujisaki-Okamoto transformation, decryption failures are handled via a reduction solving the rather unnatural task of finding failing plaintext…
Tight adaptive reprogramming in the QROM
Alex B. Grilo, Kathrin Hövelmanns, Andreas Hülsing +1
The random oracle model (ROM) enjoys widespread popularity, mostly because it tends to allow for tight and conceptually simple proofs where provable security in the standard model…
PALPAS - PAsswordLess PAssword Synchronization
Moritz Horsch, Andreas Hülsing, Johannes Buchmann
Tools that synchronize passwords over several user devices typically store the encrypted passwords in a central online database. For encryption, a low-entropy, password-based key i…
Semantic Security and Indistinguishability in the Quantum World
Tommaso Gagliardoni, Andreas Hülsing, Christian Schaffner
At CRYPTO 2013, Boneh and Zhandry initiated the study of quantum-secure encryption. They proposed first indistinguishability definitions for the quantum world where the actual indi…
