Research Interests

  • Cryptography, provable security, pairing-based cryptography
  • Automated verification of cryptographic protocols

My main research interest is the design of efficient cryptographic protocols using pairings. I am particularly interested in making efficient attribute-based encryption and signature algorithms, either by improving on previously constructed protocols, or by specializing their functionality. I'm currently trying to do away with the paring operation in identity-based and attribute-based cryptosystems by using hardware tokens.
I have also done a bit of work in electronic voting, and I would be interested in making secure electronic voting protocols more user-friendly, and find how to convince users that the protocol provides the security they expect.

I also try to teach computers how to produce or verify proofs of cryptographic protocols. It's not easy. Computers are stupid. We have had a fair bit of success so far with symmetric encryption based on block ciphers, are currently working on message authentication codes. We hope to move on to public key encryption soon. I also tried to verify security properties of an actual implementation of an e-voting protocol developed by the Norwegian government for their public elections, but unfortunately, they canned the project before we could get interesting results.
