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.
Digital Security
Highlights
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.
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.
