Fredrik Jönsson

Fredrik Jönsson is a Senior Lecturer at the Department of Computer Science, Kristianstad University, within the Faculty of Natural Science. His work bridges information theory, machine learning, and cryptography, focusing on applications like cryptanalysis using machine learning and privacy-preserving machine learning.

He earned a PhD in Information Theory (2002) and an MSc in Computer Science and Engineering (1997), both from Lund University. His research spans coding theory, stream cipher cryptanalysis, and machine learning for cybersecurity.

• Research Trends: Recent publications highlight quasi-cyclic codes, finite field GF(17) applications, and CPLEX-based code optimization. Older work includes fast correlation attacks, convolutional codes, and linear code analysis, reflecting his foundational contributions to cryptographic security.
• Collaborative Projects: Active in projects like Inventering av förutsättningar inför en eventuell ansökan om tillstånd att utfärda examen på forskarnivå, aiming to enhance doctoral degree offerings at Kristianstad University.
• Teaching: Delivers courses in computer security and supervises bachelor theses in cybersecurity, with a broader background in computer science education.
