Research Interests

My research interests span the areas of cryptography, security and game theory. My current work focuses on security analysis of lightweight cryptographic primitives, side channel attacks, homomorphic and authenticated encryption, and mathematical and algorithmic aspects of cryptology, including post-quantum cryptology.
