This postdoctoral work will tackle the crucial question of the practical security of QKD systems. Indeed, while QKD can theoretically be proven absolutely secure, practical implementations may suffer from technological and protocol-operational imperfections that an attacker could exploit in order to compromise the security of the key establishment. Effectively addressing these threats, called side-channels, is a major step towards bringing QKD systems to a maturity level suitable for industrial development and commercial use, and is now a topic raising a lot of attention in the QKD community.
The goal of the present postdoctoral project is to study side-channel attacks in QKD systems implementing both discrete and continuous-variable protocols. In particular, we will pursue the identification of side-channels in the systems under function in our laboratory in Telecom ParisTech, implement some attacks enabled by the identified side-channels, and development suitable countermeasures. The work will be primarily experimental, and will be conducted in the framework of the FP7 project Q-CERT, a EU-funded cooperation project that unites two academic partners (Telecom ParisTech, and University of Geneva) and two start-ups involved in QKD (IdQuantique and SeQureNet). The postdoctoral researcher will thus benefit from the active exchanges of knowledge between the academic partners and the start-ups of the consortium, at a local level in Paris, but also between Paris and Geneva.
