Position-Based Quantum Cryptography: Impossibility and Constructions
Harry Buhrman, Nishanth Chandran, Serge Fehr +4
In this work, we study position-based cryptography in the quantum setting. The aim is to use the geographical position of a party as its only credential. On the negative side, we s…
Random Oracles in a Quantum World
Dan Boneh, Özgür Dagdelen, Marc Fischlin +3
The interest in post-quantum cryptography - classical systems that remain secure in the presence of a quantum adversary - has generated elegant proposals for new cryptosystems. Som…
Simple Protocols for Oblivious Transfer and Secure Identification in the Noisy-Quantum-Storage Model
Christian Schaffner
We present simple protocols for oblivious transfer and password-based identification which are secure against general attacks in the noisy-quantum-storage model as defined in [KWW0…
Leftover Hashing Against Quantum Side Information
Marco Tomamichel, Christian Schaffner, Adam Smith +1
The Leftover Hash Lemma states that the output of a two-universal hash function applied to an input with sufficiently high entropy is almost uniformly random. In its standard formu…
