Karim Eldefrawy

Principal Computer Scientist, Computer Science Lab (CSL)

Karim Eldefrawy, Ph.D., is a Principal Computer Scientist at the Computer Science Laboratory (CSL) at SRI International. His research interests lie in cryptography and secure and privacy-preserving computation for distributed systems, computer-aided formal verification of cryptographic algorithms and protocols, and quantum algorithms and networking protocols for securing distributed systems. His research is funded by the Defense Advanced Research Project Agency (DARPA), the Department of Homeland Security (DHS), and the Intelligence Advanced Research Projects Activity (IARPA), and (in the past) Boeing and General Motors. He authored over 100 scientific works (65+ peer-reviewed papers and book chapters, 25+ granted and 10+ pending patents). Karim served on technical program committees of several academic conferences on security and cryptography and was the information director of ACM Transactions on Privacy and Security (formerly ACM TISSEC) from 2011 to 2015. He taught security and cryptography and distributed systems and networking courses at the University of California at Irvine (UCI) and the University of San Francisco (USF).
