About Me

Hello! I’m Abolfazl Sajadi (Abish).

A Ph.D. researcher at the Leiden Institute of Advanced Computer Science (LIACS) at Leiden University. Born on October 3, 1993, in Arak, Iran, I've been passionate about electronics and digital systems since my early teens.

I earned my Master's degree in Electrical Engineering – Digital Electronic Systems from the University of Tehran in 2021, graduating as the top student in my class. My master's thesis focused on developing a machine learning-resistant PUF-based authentication protocol for resource-constrained IoT devices.

Currently, under the supervision of Prof. Nele MentensTodor Stefanov, and Nusa Zidaric. I am working on the PROACT project, which involves the digital hardware design of lightweight cryptographic circuits. My research interests have evolved to include ASIC design, where I am focusing on pre-silicon side-channel leakage analysis to enhance hardware security. Additionally, I am exploring HW/SW co-design, especially with FPGA platforms, to optimize system performance and efficiency.

Research Interests

  • ASIC Design
  • Hardware Implementation of Cryptographic Primitives
  • Hardware Security (offensive and defensive approaches)
  • System-Level HW/SW Co-Design, particularly with FPGAs
  • Lightweight Authentication using Physical Unclonable Functions (PUFs)
  • Hardware Implementation of Machine Learning Algorithms

I believe that neural networks will become a perfect solution to many of our future challenges. My enthusiasm for ASIC design and hardware security drives me to explore innovative solutions in the field of digital electronics.
