About the position

At the Department of Information Security and Communication Technology, we have a vacancy for a Ph.D. candidate in Information Security and Communication Technology.

The biggest obstacle for the big visions and promises by 5G (and beyond) networks, about telepresence, holographic transmissions, telemedicine, and remote operations, are the network latencies in the control layer, that so far cannot go below 1ms even within the most controlled experimental environments. The 5G network's control layer uses short Polar codes with codewords from 40 up to 128 bits. Their encoding and decoding times need to be short in order to reduce the network response latency. While 4G has latency in the range of 50ms, 5G is expected to have a latency of around 10ms (up to 5 times faster than 4G). The newest efforts push the latency further down to 1ms – 2ms. But 6G networks will require 100-times the data throughput of 5G and will need to expand to cover from hundreds of thousands up to millions of access points. To achieve that, codes that enable sub-millisecond latency have to be designed.

This scenario for the future 6G wireless networks includes two research areas: 1. Coding theory, with short codes that can offer better (shorter) latencies than the current standard used in 5G – the Polar codes; 2. Coding theory that addresses the challenges of the edge computing, with the design of locally reparable codes.

Research objectives of the position:

1. Develop, fine-tune, implement, and test short error-correcting codes that have better performances than Polar codes, and reduce latency in sub-millisecond ranges. 
2. Develop, fine-tune, implement, and test locally reparable codes suitable for the edge-computing environments that will increase the data throughput and reduce the latency in sub-millisecond ranges. 

The position's working place is NTNU campus in Trondheim. You will report to the Head of the Department.

Duties of the position

  • The PhD candidate will work on challenging research problems related to design of linear codes for achieving sub-millisecond latencies in latest wireless networks such as 5G and its successors.
  •  The candidate will also have up to 25% of teaching duties in related areas.
  •  The candidate will be encouraged to have a research stay with one of the collaborating universities outside Norway during the research period.

The position is part of SFI NORCICS, the new 8-year research-based innovation Norwegian Center for Cybersecurity in Critical Sectors. These sectors include electricity production and distribution, oil & gas production and distribution, manufacturing, healthcare, industrial production, financial services, transportation, smart districts. NORCICS follows a holistic, comprehensive and systemic approach addressing people, processes and technology to protect critical sectors throughout the cybersecurity core functions (identify, protect, detect, respond, recover). NORCICS has partners from academia, research, the public sector and the industry. For more information about NORCICS .

There are several PhD positions announced within the context of NORCICS. You are encouraged to apply for all positions that fit your background and interests. Integrated PhD study candidates are welcome to apply.

Required selection criteria

The PhD-position's main objective is to qualify for work in research positions. The qualification requirement is that you have completed a master’s degree or second degree (equivalent to 120 credits) with a strong academic background in Mathematics, Computer Science, Communications technology or related areas with a grade of B or better in terms of NTNU’s grading scale. If you do not have letter grades from previous studies, you must have an equally good academic foundation. If you are unable to meet these criteria you may be considered only if you can document that you are particularly suitable for education leading to a PhD degree.

  •  Academic background as listed above.
  • Excellent English language skills (written and oral).
  • Good organization and communication skills with interest in wider context of own research and ability to engage in cross-disciplinary teams.
  •  Eager to disseminate research results through publications and presentations at international conferences.

Preferred selection criteria

  • Knowledge of Coding theory is desirable.
  • Knowledge of Algebra is desirable.
  • Knowledge in Cryptography is desirable.
  • Experience with some programming languages is desirable.

Personal characteristics

  • Be scientifically curious and open to new research challenges.
  • Demonstrate independence and persistence in addressing technical problems.
  • High motivation for research work and ability to work independently.
  • Be flexible and reliable, with ability to work effectively independently and as part of a team.
