Randomness Extraction via Delta-Biased Masking in the Presence of a Quantum Attacker
Serge Fehr, Christian Schaffner
Randomness extraction is of fundamental importance for information-theoretic cryptography. It allows to transform a raw key about which an attacker has some limited knowledge into…

A Tight High-Order Entropic Quantum Uncertainty Relation With Applications
Ivan B. Damgaard, Serge Fehr, Renato Renner +2
We derive a new entropic quantum uncertainty relation involving min-entropy. The relation is tight and can be applied in various quantum-cryptographic settings. Protocols for quant…

Cryptography In the Bounded Quantum-Storage Model
Ivan Damgaard, Serge Fehr, Louis Salvail +1
We initiate the study of two-party cryptographic primitives with unconditional security, assuming that the adversary's quantum memory is of bounded size. We show that oblivious tra…
