Luleå University of Technology is growing rapidly with world-leading expertise in several research areas. We shape the future through innovative education and groundbreaking research results, and based on the Arctic region, we create global social benefits. Our scientific and artistic research and education are conducted in close collaboration with international, national and regional companies, public actors and leading universities. Luleå University of Technology has a total turnover of SEK 2 billion per year. We are currently 1,500 employees and have 17,900 students. In the coming years, billions of kronor will be invested in Norrbotten and Västerbotten in major projects aimed at a more sustainable society nationally as well as globally. Luleå University of Technology is involved in several of these highly topical research projects and the social transformation that follows. We have a wide range of programs to match the skills that are in demand. We hope you will help us build the sustainable businesses and societies of the future. Cybersecurity at the Department of Computer Science, Electrical and Space Engineering is now looking for a PhD student specializing in 6G and satellite communications to contribute to our growing activities. Subject description Cybersecurity focuses on technical security aspects and protection of systems connected to the internet and includes protection of software, data and hardware. Project description Luleå University of Technology will start a multidisciplinary competence center in 2025 together with KTH and RISE in 6G and satellite communication, Sustainable Mobile Autonomous and Resilient 6G SatCom. Ericsson, Saab, Ovzon, Beyond Gravity, Forsway, Satcube, Swedish Space Corporation (SSC), NorthernWaves, Primekey, Airforestry, Swedish Post and Telecom Authority (PTS), European Incoherent SCATter Scientific Association (EISCAT), Swedish Transport Administration, Swedish Forest Industries Federation, Region Norrbotten, Region Västerbotten, Region Stockholm, Eutelsat-OneWeb, Airbus, Viasat and Thales Alenia Space are also contributing to the work. The aim is to integrate traditional land-based mobile communications and space-based satellite communications into 6G, which is expected to be in use in the 2030s. The vision is that mobile communication services will be seamlessly available to anyone with a 6G device, anywhere, anytime. The focus will be on sustainability and energy efficiency, reliability and resilience, as well as system interoperability and always-on artificial intelligence. To achieve the vision, research will focus on improving hardware for both 6G devices and space-based satellites, developing signal processing methods that handle high signal losses and are robust to space-based interference, developing network technologies that integrate terrestrial and space systems, and developing new intelligent applications that combine communication, location and remote sensing. We are looking for a motivated and innovative PhD student to join our research team to develop cutting-edge solutions that integrate 6G and satellite communications in a secure way. More specifically, the work involves developing independent authentication services for large-scale systems that enable the transition from today's symmetric to future asymmetric crypto solutions. The idea is to create a quantum-safe, efficient and automated PKI (Public Key Infrastructure) for the 6G-NTN of the future, where trade-offs around flexibility, scalability, autonomy and optimization are made with regard to the fact that the systems will execute in space. In addition, work is planned in path-aware networking so that traffic avoids nodes or links that are not secure and the development of new secure communication protocols for 6G-NTN where handover between terrestrial systems and satellite systems takes place securely. Duties and responsibilities A PhD position involves both theoretical and practical work. As a PhD student, you will be trained in scientific work in the form of publishing scientific articles in journals and at national and international conferences. You will also take compulsory and optional doctoral courses. In addition, you may have the opportunity to try out the role of teacher. As a researcher, you will work as a neutral party in many contexts, providing a great opportunity to learn how to run challenging development projects. Qualifications We are looking for analytical and motivated colleagues who can carry out advanced research both independently and in collaboration with others in our research group. You should have a Master's degree in Computer Engineering or equivalent. The applicant should have good knowledge of software development and computer science, and good oral and written communication skills in English. Additional knowledge in mathematics, computer security or cryptosystems is an advantage, but not a requirement. Previous experience in research and publications would also be an advantage. For further information on specific PhD programs see curricula for doctoral studies in the Faculty of Engineering Most of the cybersecurity staff are currently male, so we welcome female applicants. Information about the program Employment as a doctoral student is limited to 4 years, teaching and other departmental service may be added up to 20% of full time. Place of employment: Luleå or Skellefteå. Access March 1, 2025 or by agreement. Travel within and outside the country occurs. Security clearance may be required.
