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.


RESEARCH

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:

Making an asymmetric PAKE quantum-annoying by hiding group elements

M. Tiepelt, E. Eaton, D. Stebila. In ESORICS 2023.
