Research Interests
Most of research evolves around side-channel attacks and countermeasures for post-quantum cryptography. This includes new attacks on algorithms, e.g. from NIST's Post-Quantum Competition and their protection against passive side-channel attacks in software as well as in hardware. Regarding the verifiability of such a countermeasure, I mostly work with actual measurements but am also interested in formal methods. I'm furthermore interested in the practical limitations of countermeasures, especially when it comes to ASIC implementations and physical effects not fully covered by current models.

On the Impact of the Resolution on Side-Channel Attacks
Description
For power side channel attacks, it is common to capture traces with some kind of oscilloscope. Depeding on the model in use one has several degrees of freedom on the properties of such a measurement. This includes the sampling rate of the scope as well as the resolution of the ADC.
The goal of this seminar topic is to summarize findings on the impact of the resolution of an oscilloscope on the resulting side channel attack.

Implementation of High-Assurance Cryptography
Description
Cryptographic implementations in high-level languages like C often suffer from compiler induced side-channel issue which allow e.g. to extract a secret key via the timing behaviour of the implementation. Implemeting in assembly is on the other hand error prone and laboursome. This topic is therefore about implementing and/or verifying certain aspects of a Post-Quantum Cryptographic algorithm in Jasmin [1]. Jasmin allows for exact control of the underlying hardware while providing more abstraction and support than pure assembly. It furthermore allows for formal proofs of the implemented algorithm.

Prerequisites
- Programming skills in C and either x86 or ARM (Thumb) assembly
- Basic understanding of (timing) side-channels
- Knowledge of a formal proof system/assitant
