Doctoral student, Network security in 5G and beyond 5G systems

The University of Oulu ( is one of the largest universities in Finland, with approximately 16 000 students and 3 000 employees. The University of Oulu Graduate School (UniOGS) ( provides the framework and conditions for high-quality, research-driven doctoral education at the University of Oulu, and field-specific doctoral training is provided by its multidisciplinary doctoral programs. The position is located at the Centre for Wireless Communication – Networks and Systems (CWC-NS) research unit (, Faculty of Information Technology and Electrical Engineering (ITEE, see

The Centre for Wireless Communications consists of two intertwined research groups, namely Centre for Wireless Communication – Radio Technologies (CWC-RT) and Centre for Wireless Communications – Networks and Systems (CWC-NS).  Research at CWC-NS focuses on 5G and beyond, IoT, secure virtualized networks, disaster prevention and recovery ICT, medical ICT, smart energy grids and mobile clouds. CWC employs altogether a staff of 150 including 10 professors. Its collaborative network includes several major companies and research universities.

Applications are invited for a one-year, full-time doctoral student position starting at the earliest on 01.02.2019 in an Academy of Finland project at the CWC-NS research unit. A trial period of 6 months is applied in the position.

The student selected for the task will be working on the design of secure and/or privacy-preserving protocols and architectures for 5G and beyond 5G networks. The main application area will be network Software Defined Networking (SDN), Network Function Virtualization (NFV) and Network Slicing based 5G and Industrial IoT networks where applications are typically latency-sensitive and produce high amounts of data requiring fast processing and refining.  During the studies, the student should be applying (a combination of) various advanced cryptographic technologies, such as light weight authentication mechanisms, encryption algorithms, machine learning and novel technologies such as blockchain, secure transaction methods and smart contracts to design secure communication solutions that achieve a good balance between security, user privacy and usability. The work will include real-world prototyping with relevant technologies. Good knowledge in applied mathematics and experience in software implementations highly required.

The position is supervised by Adj. Prof. Madhusanka Liyanage (technical supervision) and. Assoc. Prof. Mika Ylianttila (responsible supervisor).

Requirements for a doctoral student

Candidates should have a M.Sc. in one of the following fields: communications engineering, computer science, software engineering or another relevant subject by the time of the start date; proven networking software (e.g., TCP/IP protocol stack, SDN, NFV, OpenStack, Docker) development skills with at least one relevant programming language such as Python, Java or C++; proven ability to document and publish the research findings in top conference proceedings or journals; motivation and dedication to pursue doctoral degree studies and research work which has the potential to be published in high ranking publications.


The salary of the selected doctoral student will be set on levels 2 – 4 of the national salary scale for the teaching and research staff of Finnish universities. In addition, a supplementary remuneration will be given for personal achievement and performance (max. 46,3 %). The salary (before tax) currently ranges from approximately 2300 to 3500 Euros/month for full-time employment, depending on qualifications, performance, and progress of the doctoral studies.


Applications must be submitted using the electronic application form by 31st December, 2018, 23:59 (Finnish local time). Please attach the following documents as a single pdf file: your CV with publications, a motivation letter describing prior knowledge and research interests and career plans, your certificates/Diplomas (Scanned electronic copies of diplomas and transcripts of the records of relevant previous degrees. If the original documents are not in English, Finnish or Swedish, each document must be accompanied by an official certified translation into English or Finnish.), as well as two reference letters. The application letter should also contain possible starting dates.
