The Research I Like

My research interests lie in the area of homomorphic cryptographic primitives, data authentication, and user privacy. I am particularly fascinated by cryptographic applications of mathematical objects and new construction that may derive from it.

I am actively working on: multi-key and homomorphic cryptosystems, signatures with advanced properties, private & compact digital storage solutions, verifiable computation, and privacy-enhancing technologies. Below is a visual overview of my lines of research (Titles and references written in black color refer to papers published or accepted for publication.

VR starting grant on Progressive Verification of Cryptographic Schemes (4M SEK / 4 years)

Computational devices are ever more present in our lives. As we shift towards smart­ cities, we will see an increased deployment of embedded devices to support ubiquitous payments, assisted driving, smart­-locks and much more. To ensure the safety of digitalized societies, devices that collect and process (sensitive) data need to do so in a secure and efficient way. This often involves verification mechanisms, e.g., to check the validity of digital signatures, certificates, credentials, but also to verify data and process integrity. Modern post-quantum secure schemes are not designed to run on resource constrained devices. The main obstacles are efficiency and storage. This project focuses on the design and study of progressive verification mechanisms. Unlike standard verification tech­niques that return a binary output (accept/reject) only at the very end of the execution, progressive verification builds confidence on the validity of an instance step­-by-step, and can early reject fallacious inputs. This frame­ work opens the possibility for verifiers that are computationally weak, with limited storage available, or running out of battery, to dynamically adjust their soundness (accuracy of the verification outcome) to their current performance.
