Associate Professor
Waterloo, Ontario, Canada
Summary
🤩
RockstarDouglas Stebila is an Associate Professor of cryptography at the University of Waterloo with 15 years of experience focused on strengthening Internet security protocols and building practical post-quantum cryptosystems. He combines applied cryptography expertise—key exchange, digital signatures, PKI, and elliptic-curve work—with hands-on contributions to real-world projects such as the widely used open-quantum-safe/liboqs, where he implemented a new KEM API and post-quantum KEMs like SIKE and Kyber. His research and engineering bridge theory and practice, improving TLS/SSH security while adding rigorous tests and documentation to production libraries. Based in Waterloo, Canada, he also explores less obvious but high-impact areas such as client puzzles/proofs-of-work and quantum cryptography, bringing a systems-minded approach to historically theoretical problems.
