About me

I'm an Assistant Professor in cryptography at McMaster University in Hamilton, Ontario, Canada. My research focuses on improving the security of Internet cryptography protocols such as SSL/TLS and SSH.

Research

My research interests include:

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

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

Pictures

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:
