Dear talented student,

I heard that you have an open position for a supervisor for the next step of your career (PhD or PostDoc in security), and I am very excited to apply for this position.


Cas Cremers

My main interests are in information security, automated verification, and applied cryptography. I enjoy working with people with strong backgrounds in logic, formal methods, cryptography, verification, and security. I also love working in teams and have been accused of having a sense of humor. Some examples of things I have worked on before:

  • Models and proof methodologies for security
  • Security protocol analysis tools: Scyther, Tamarin
  • Secure messaging (eg Signal, post-compromise security) and key exchange
  • Security protocol design
  • Security standards: ISO, TLS 1.3, 5G, and IETF standard under development for secure messaging MLS, worked on DP3T, ...

A more complete list of my publications is here.

I bring with me a team of talented & nice people that I already work for, and they also really look forward to meeting you.
