Research Interests

My research focuses on efficient hardware implementations for post-quantum cryptography. More specifically, I am interested in hardware acceleration for digital signature algorithms on RISC-V platforms for embedded systems. This includes not only performance optimizations, but also aims to improve power and energy consumption. Another important aspect is securing implementations against physical attacks, i.e. side-channel and fault-attacks. Besides FPGA prototyping I am also involved in ASIC design and tape-out. Additional interests include advanced cryptographic approaches like homomorphic- or attribute-based encryption. In short:

• Post-Quantum Cryptography
• Efficient Hardware Implementations
• Countermeasures against Physical Attacks
• FPGA and ASIC design

I also contributed to the NIST submissions CROSS, LESS and FuLeeca
