Postdoc on Physical Layer Security for Free-Space Optical Satellite Channels

Postdoc on Physical Layer Security for Free-Space Optical Satellite Channels

Published Deadline Location
6 Mar 2 Jun Eindhoven

Job description

Are you fascinated by the idea of a next-generation, secure, high-speed space Internet which will enable high-bandwidth and secure communications to every corner of the Earth? Join us on this exciting EU research project with prestigious institutes, observatories and companies throughout Europe. And a warm word of welcome to you from the Information and Communication Theory lab (ICT-lab) at the TU/e!

Job Description

Quantum key generation over the satellite is envisioned as part of the core infrastructure for future long-distance, resilient, secure communications. Though the optical losses in the free space optical channel are considerably less than in the fiber channel, for large distances the secure key rates are still very limited. This means that the number of keys, the length of the keys and the rate at which they can be refreshed are limited. To overcome this and enhance the security, in addition to quantum key generation, classical key generation using physical layer security can take place. The classical key generation can be added - on top of the quantum key generation - and inherits its security thanks to the low-divergence of laser beams, smart coding and by exploiting physical optical channel properties.

As a post-doc you are asked to perform and lead research in this area and come up with innovative ideas. The research includes performing the secrecy analysis and coming up with physical layer security schemes (e.g., one-way and two-way protocols) to complement existing (quantum) key generation schemes. All with the aim of enhancing the security, and enabling higher secure key rates and longer-distance secure communications.

This position is part of the collaborative EU research project LaiQa which develops key technologies for a global quantum Internet enabled from space. The consortium consists of the Institute of Communication and Computer Systems (ICCS, Greece), the applied research organization TNO (Netherlands), Quantum Technology Laboratories GmbH QTLABS (Austria), Quantum Space Systems GmbH QSSYS (Germany), the National Observatory of Athens (Greece), the National and Kapodistrian University of Athens (Greece), and Thales Alenia Space (Italia).

About us

Eindhoven University of Technology is an internationally top-ranking university in the Netherlands that combines scientific curiosity with a hands-on attitude. Our spirit of collaboration translates into an open culture and a top-five position in collaborating with advanced industries. Fundamental knowledge enables us to design solutions for the highly complex problems of today and tomorrow. 

Curious to hear more about what it's like as a PhD candidate at TU/e? Please view the video.

The Information and Communication Theory Lab (ICT Lab) at TU/e is a globally recognized research group focusing on information and communication theory, and its applications. At the ICT Lab, we study information processing in a broad sense. We focus on finding fundamental limits but also on the data processing techniques (often codes and digital signal processing algorithms) and architectures that aim at approaching these limits. Main areas of interest are source coding, channel coding, multi-user information theory, security, and machine learning. We typically use information-theoretical frameworks to model the scenarios under investigation. This allows us to find out what the optimal trade-offs are. The scenarios that we study often result from close interaction with industry. Curious to learn more about research at the ICT Lab? Please view this video.
