Phd on physical layer security for laser satellite communications

PhD on Physical Layer Security for Laser Satellite Communications

Functieomschrijving

We foresee a future where lasers light up the sky to enable high-bandwidth and secure communications to every corner of the Earth. Thanks to the low divergence of laser beams, these optical/infrared signals are much harder to intercept and to jam in comparison to conventional radio communications. However, more security guarantees are needed. Therefore, in this project we invite you - as a candidate PhD - to join the research on physical layer security schemes for free space optical (FSO) channels. Join the information and communication theory lab (ICT Lab) on this exciting EU research project with prestigious institutes, observatories and companies throughout Europe.

Quantum key distribution over satellite networks 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 in practice that the number of keys, the length of the keys and the rate with which they can be refreshed is limited. To overcome this and enhance the security, in addition to quantum key distribution, classical (optical) key distribution can take place. The classical key distribution can be added - on top of the quantum key distribution - and inherits its security thanks to the low-divergence of laser beams and by exploiting physical optical channel properties and smart two-way handshakes.

As a PhD candidate, you are asked to perform research in this area and come up with innovative concepts. The research includes FSO channel modelling, performing secrecy/capacity analysis for this FSO channel, performing comparative analysis between various methods in terms of their performance, and devising novel physical layer security schemes with the aim to enhance the security, enable 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).

Functie-eisen

• Master of Science degree in Electrical Engineering, Telecommunications or a related topic, with excellent grades.
• Good understanding of physical-layer communications, information theory and (optical) wireless channel models.
• Critical thinking attitude and ability to come up with novel concepts and innovations.
• Ability to professionally cooperate with other students, researchers and external partners.
• Good proficiency in written and verbal English, along with strong communication skills.

Arbeidsvoorwaarden

A meaningful job in a dynamic and ambitious university, in an interdisciplinary setting and within an international network. You will work on a beautiful, green campus within walking distance of the central train station. In addition, we offer you:

• Full-time employment for four years, with an intermediate evaluation (go/no-go) after nine months. You will spend 10% of your employment on teaching tasks.

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.
