Diego F. Aranha

Associate Professor
Aarhus University

I am an Associate Professor in the Department of Computer Science at Aarhus University, Denmark, where I conduct research in cryptographic engineering and security of real-world systems. I also lead the Cybersecurity Work Package at DIGIT and contribute to COBRA as Principal Investigator.

I have received two Google Latin America Research Awards for privacy, and the MIT TechReview’s Innovators Under 35 Brazil Award for my work in electronic voting.

Research Interests

  • Efficient secure cryptography in software
  • Elliptic Curve Cryptography (ECC) and Pairing-Based Cryptography (PBC)
  • Security in Wireless Sensor Networks (WSNs) and the Internet of Things (IoT)
  • Side-Channel Analysis (SCA) and countermeasures
  • Cryptography based on physical assumptions (PUFs)
  • Privacy-preserving computing
  • Computational anonymity
  • Electronic voting
  • Systems security
