I am a Professor of Computer Science at Boston University, a founder of Sealance Corp., and until recently, a professor at Tel Aviv University's School of Computer Science and a research scientist at Columbia University.
My research focus is information security, cryptography and algorithms. I am particularly interested in what happens when cryptographic systems meet the real world, where computation is faulty and leaky.
I head the Laboratory for Experimental Information Security (LEISec), where my group investigates side-channel information leakage in computers through physical emanations (e.g., acoustic, electric and electromagnetic) and software (e.g., cache contention in local and cloud computing), and networks (e.g., identifying encrypted videos).
I cofounded SCIPR Lab, where we construct cryptographic zero-knowledge SNARK proof systems for ensuring the integrity of computation conducted on untrusted, faulty and malicious platforms.
Other research interests include tamper resilience, homomorphic encryption, special-purpose code-breaking hardware and various aspects of network and systems security. See my publications for more information.
