Quantum Cryptography Beyond Quantum Key Distribution
Anne Broadbent, Christian Schaffner
Quantum cryptography is the art and science of exploiting quantum mechanical effects in order to perform cryptographic tasks. While the most well-known example of this discipline i…
Continuous-Variable Protocols in the Noisy-Storage Model
Fabian Furrer, Christian Schaffner, Stephanie Wehner
We present the first protocol for oblivious transfer that can be implemented with an optical continuous-variable system, and prove its security in the noisy-storage model. This mod…
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…
Quantifying the Leakage of Quantum Protocols for Classical Two-Party Cryptography
Louis Salvail, Christian Schaffner, Miroslava Sotakova
We study quantum protocols among two distrustful parties. By adopting a rather strict definition of correctness - guaranteeing that honest players obtain their correct outcomes onl…
