Digital Security

Department

The Digital Security (DiS) department (part of Institute for Computing and Information Sciences) conducts research across cybersecurity, cryptography, and privacy. Our focus includes symmetric and post-quantum cryptography implementation, side-channel analysis, software and mobile network security, online tracking, and privacy-oriented solutions for identity and data management. This work is integrated with Radboud iHUB, which explores the intersection of digitalisation and society.

Highlights

Vidi-berichtgeving

Vidi grants for research into polarisation, privacy, Parkinson and more

The Netherlands Organisation for Scientific Research (NWO) has awarded thirteen Nijmegen researchers Vidi funding of up to 850,000 euros. This will allow them to develop their own line of research and set up a research group over the next five years.

Computer output always lags behind; law is forward-looking

Automatisering van het recht is risicovol, en daarom is het belangrijk dat de juridische informatica van de toekomst door juristen en informatici samen ontwikkeld wordt en in lijn is met rechtsstatelijke waarborgen, aldus Mireille Hildebrandt.

Research

The Digital Security department focuses on three core research areas that form the foundation of digital security: cryptography, security, and privacy. Each area brings its own unique perspective and methodologies to protect our digital world.

Cryptography

Our research in cryptography focuses on two key areas. In symmetric crypto, we develop energy-efficient cryptographic solutions optimized for both small devices like RFID tags and high-bandwidth applications requiring minimal heat production. For post-quantum crypto, we design innovative forms of asymmetric cryptography that remain secure against future quantum computing attacks, ensuring long-term security for electronic signatures and key establishment protocols.

Security

Our research in security spans multiple critical domains: hardware security and side-channel analysis to protect against physical attacks, innovative approaches in AI & security leveraging machine learning, robust software security development techniques, and cutting-edge mobile network security with a focus on safeguarding 5G networks against emerging threats.

Privacy

Our privacy research combines technical innovation with legal and human-interface considerations, conducted through the Radboud iHUB's interdisciplinary framework. We explore Privacy-by-Design principles, investigate web tracking technologies and solutions like Tor, while developing privacy-friendly solutions for identity and data management. Our work integrates legal aspects of IT, particularly focusing on GDPR compliance and AI regulations, through collaboration with multiple faculties including humanities, law, social sciences, and the Data Science group.

Symmetric Cryptography with Asymmetric-hardware Leveraged Architecture (SCALAR)

We use countless systems that rely on cryptography. Many of these systems use symmetric cryptography. This project will attempt to adapt the benefits of asymmetric cryptography to the symmetric variant.

Education

The department offers various Bachelor's and Master's courses and is closely involved in the Bachelor's Computing Science and the Master's specialisation Cyber Security and Cyber Security and AI
