Open public Internet access is an important building block of our communication. Networks that can provide connectivity around the globe have large potential, but still rely on attack-prone Wi-Fi without metadata protection. As a PhD Candidate, your research into mobile networks will help design and implement an open 5G infrastructure with improved privacy and security.

Within the project, the research focus can be tuned to your interests. You will be expected to investigate different classes of attacks on 5G mobile networks. This not only requires the design and implementation of simulation models, but also the setup of measurement frameworks and lab network setups. In a following step, you will process and analyse the collected data in order to draw conclusions. To investigate possible new attack vectors and defences against present-day attacks, you will transfer and apply common methods from other research areas in order to find creative new solutions.

Besides research, the position involves teaching responsibilities regarding the Master's course in Advanced Network Security. This includes supporting the course through the definition of practical exercises that focus on challenges in the context of mobile network security. You will have a teaching load of up to 10%.

• You hold a Master’s degree in Computer Science or a relevant discipline.
• You have excellent programming skills.
• You have a good command of spoken and written English.
• You have good communication skills and the ability to communicate with peers and stakeholders.

Fixed-term contract: you will be appointed for an initial period of 18 months, after which your performance will be evaluated. If the evaluation is positive, the contract will be extended by 2.5 years (4 year contract).

• Employment for 1.0 FTE.
• The gross starting salary amounts to €2,443 per month based on a 38-hour working week, and will increase to €3,122 in the fourth year (salary scale P).
• You will receive 8% holiday allowance and 8.3% end-of-year bonus.
• You will be employed for an initial period of 18 months, after which your performance will be evaluated. If the evaluation is positive, the contract will be extended by 2.5 years (4 year contract).
• You will be able to use our Dual Career and Family Care Services. Our Dual Career and Family Care Officer can assist you with family-related support, help your partner or spouse prepare for the local labour market, provide customized support in their search for employment and help your family settle in Nijmegen.
• Working for us means getting extra days off. In case of full-time employment, you can choose between 29 or 41 days of annual leave instead of the legally allotted 20.

Additional employment conditions Work and science require good employment practices. This is reflected in Radboud University's primary and secondary employment conditions. You can make arrangements for the best possible work-life balance with flexible working hours, various leave arrangements and working from home. You are also able to compose part of your employment conditions yourself, for example, exchange income for extra leave days and receive a reimbursement for your sports subscription. And of course, we offer a good pension plan. You are given plenty of room and responsibility to develop your talents and realise your ambitions. Therefore, we provide various training and development schemes.

You will be appointed in the Digital Security Group of the Institute for Computing and Information Sciences (iCIS) at the Faculty of Science. The faculty is internationally renowned for the quality of its research. The Digital Security Group is one of the leading groups in computer security in the Netherlands and Europe, with, for example, 4 ERC grants in the last decade and a strong involvement in European projects. To further strengthen our group, we are looking for a PhD candidate in the area of computer security. The research focus will be on mobile network security.
