2x PhD position on transitioning internet protocols and applications to post-quantum cryptography

Research / Academic

You will perform your research as part of the DACS group, the Twente University Centre for Cybersecurity Research (TUCCR) and the international context. Interaction with international network operators and Internet standards bodies, such as the Internet Engineering Task Force (IETF), will also be part of the project. You will publish and present your work at international conferences and in journals. You will also have the opportunity to present your work in the Internet operator community, e.g., at RIPE meetings. You will collaborate and interact with a second PhD candidate in the same project, but with a different focus.

Cryptographers are developing post-quantum cryptography (PQC) that is secure against attacks with quantum computers. While much progress has been made in developing and trialling algorithms, we lack a complete view of the problem space. More boldly: we cannot answer the question "What if the whole Internet had to switch to PQC?". The SHARQS project (a Systematic Holistic Approach to Re-engineering a Quantum-Safe Internet) aims to tackle this question.

In the SHARQS project, we will empirically establish the algorithm life-cycle in Internet protocols and applications and use a model-driven approach to test the feasibility of replacing existing algorithms with PQC alternatives, which may have vastly different properties in terms of processing, bandwidth and memory requirements. The outcomes of the project will be actionable, empirically backed advice for operators, standards bodies and policymakers. SHARQS targets both the transition of the "mainstream" Internet and specific applications and protocols used in the context of the Internet of Things and Industrial Control Systems. This vacancy consists of 2 different PhD positions. Each position has a different focus and we urge you to state your preference in your motivation letter.

PhD position 1: Your research will focus on the challenges of transitioning the Internet-of-Things and Industrial Control Systems to post-quantum cryptography.

PhD position 2: Your research will focus on the challenges of transitioning the "mainstream" Internet to post-quantum cryptography.
