Quantum Communication with Deniability

Financement: Fonds National de la Recherche > CORE
Date de début: 1 juillet 2018
Date de fin: 30 juin 2021


The goal of this project is to conduct a thorough formal analysis of the promising, but poorly understood field of deniable quantum communication. It will entail a systematic analysis and classification of the quantum primitives that are relevant for deniability, and further give precise definitions of deniability and related concepts in quantum protocols. The results will be both in the form of impossibility, as well as feasibility theorems with corresponding protocols. This will be both in the form of modifying existing QKD protocols to restore deniability, as well as devising new quantum protocols that provide deniability for key exchange and beyond, e.g. for e-voting.
