Cryptography from Noisy Storage
Stephanie Wehner, Christian Schaffner, Barbara Terhal
We show how to implement cryptographic primitives based on the realistic assumption that quantum storage of qubits is noisy. We thereby consider individual-storage attacks, i.e. th…
Secure Identification and QKD in the Bounded-Quantum-Storage Model
Ivan Damgaard, Serge Fehr, Louis Salvail +1
We consider the problem of secure identification: user U proves to server S that he knows an agreed (possibly low-entropy) password w, while giving away as little information on w…
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…
