About me

I'm an Associate Professor of cryptography in the Department of Combinatorics & Optimization at the University of Waterloo in Waterloo, Ontario, Canada. My research focuses on improving the security of Internet cryptography protocols such as SSL/TLS and SSH, and developing practical quantum-resistant cryptosystems.


My research interests include:

  • Applied cryptography: key exchange protocols; post-quantum cryptography; digital signatures; public key encryption; client puzzles / proofs of work; elliptic curve cryptography; quantum cryptography
  • Internet security: network security protocols (SSL/TLS, SSH, Tor, …); public key infrastructure (PKI); authentication

My full list of publications and presentations are available online. My most recent papers are:

A. Menezes, D. Stebila. In IEEE Security & Privacy, 2021.

E. Eaton, D. Stebila, R. Stracovsky. In LATINCRYPT 2021.

N. Bindel, D. Stebila, S. Veitch. In LATINCRYPT 2021.

P. Schwabe, D. Stebila, T. Wiggers. In ESORICS 2021.


I'm fortunate to be able to travel a lot. I take lots of pictures on my trips. The best of my photos are posted in my galleries. My most recent galleres are:


I have a blog. I have not been very good at updating it lately, but here are my most recent posts:
