Biography

I am a second-year Ph.D. student at Know-Center GmbH in cooperation with the Institute of Applied Information Processing and Communications (IAIK) at Graz University of Technology. Before this, I completed my BSc and Dipl.-Ing. (equivalent to MSc) in computer engineering at TU Graz, with a focus on IT-Security. My master’s thesis is the design and implementation of an FPGA-based coprocessor for signature creation and verification of Picnic, a post-quantum secure digital signature scheme.

Interests

  • Fully Homomorphic Encryption (FHE)
  • Multiparty Computation (MPC)
  • Post-Quantum Signatures
  • Efficient Implementations
  • Ciphers for MPC and FHE
