I am working on various topics in the area of hardware security. So far mainly on following topics:

During my current research

  • Side Channel Analysis
  • Hardware Reverse Engineering
  • Physical (Fault) Attacks
  • Self/Full Encrypting Devices
  • Pattern and Image Processing in VLSI circuits
  • Secure Storage Elements
  • Forensics (Smartphones and Mass Storage)


  • Bachelor and Master theses:
    • Image Processing in Hardware Reverse Engineering
    • Clock Bending
    • Accelerating Side Channel Analysis with Distributed and Parallelized Processing
    • Hidden Malware in full encrypted HDDs
    • Photon Emission Analysis
    • SSD - Side Channel Analysis

If any of these topics sound interesting to you, feel free to contact me.
