Description
Leader of the group Computer Security: Marten van Dijk.
The Computer Security group contributes to making our society a safe place with digital and physical infrastructures that can be trusted to have the best interest of citizens and industry in mind. Our work constructively contributes new mechanisms and solutions to security problems.
We are committed to bringing rigorous cryptographic style thinking to security engineering. We study, analyze, and design secure computing environments from various perspectives such as secure processor architectures and cyber physical system security but also secure machine learning functionalities. We provide a holistic approach and use various techniques for reasoning about security, safety, and resilience ranging from formal methods to cryptographic proofs.

Java Bug Fixed with Formal Methods CWI
Researchers from CWI fixed a bug in the widely used object-oriented programming language Java in February 2015. They found an error in a broadly applied sorting algorithm, TimSort, which could crash programs.
Minder fouten in features door delta modelling
Bij het programmeren van nieuwe features in software worden makkelijk veel fouten gemaakt. De code van meerdere features grijpt vaak in op dezelfde plek, en zo kan de code van de ene feature soms ongemerkt die van een andere overschrijven.
Fewer errors in software features by using delta modelling
When new features are being written into software code, errors can easily be made. This is due to the fact that feature code often interacts in many different places in the software.
