Tyge Tiessen

Tyge Tiessen is an Associate Professor in the Department of Applied Mathematics and Computer Science at the Technical University of Denmark (DTU), where he is affiliated with the Cybersecurity Engineering group and the Center for Quantum Technologies. His research lies at the intersection of theoretical and applied cryptography, with a focus on symmetric key algorithms.

• PhD in Trusted Cryptography, Technical University of Denmark (2016)
• Supervised research in cryptanalysis and block cipher design

His research interests include cryptanalysis, block cipher design, differential and higher-order differential attacks, boomerang probabilities, and cryptographic primitives such as AES and LowMC. He applies mathematical rigor to evaluate and enhance the security of symmetric cryptographic systems.

The trend in his recent publications shows a consistent focus on foundational aspects of symmetric cryptography, particularly in analyzing attack vectors like boomerang and integral distinguishers, with increasing relevance to lightweight and post-quantum schemes. His work bridges theoretical analysis with practical implications for secure system design.

He has contributed to impactful research projects, including long-term security for big data and intrusion detection for connected and autonomous vehicles. As a supervisor, he has guided PhD students such as Bjørn Egil Dahl Kidmose and Andreas B. Kidmose, contributing to the next generation of cybersecurity researchers.

Tyge Tiessen is actively involved in research teams focusing on cybersecurity and quantum-safe cryptography at DTU. His lab work centers on formal analysis of cryptographic algorithms and developing robust defenses against emerging threats in digital infrastructure.
