I'm happy to supervise any students wishing to graduate in the area of privacy, identity management, applied cryptography. I maintain a separate
page with student guides.
to discuss a suitable project. External projects
are certainly a possibility. The following list of project summaries give you an idea of the kind of assignments that are currently open.
- UbiKiMa is a ubiquitous key management app for Android. It is a password manager for existing websites, but also allows public key based authentication on websites that support it. The app is still a rough prototype, that could be polished considerably. Also the underlying protocols could do with an analysis and probably some improvements. I am looking for a student that can do all of this...
- Efficient implementations of Attribute Based Credentials
- Out group has implemented Idemix credentials on smart cards in the Irma project. We are developing a new cryptographic scheme for such attribute based credentials that promise to be much more efficient while being also much more secure. The goal of this assignment is to implement the proposed scheme and analyse it.
- Privacy Coach
- Think of ways how you can use a mobile device to protect your privacy...
- Strengthening the binding between people and their on-line credentials.
- Within the IRMA project, we are developing a platform for attribute based credentials, where the credentials are stored on a smart card. Credentials are personal, and it should be impossible to use the credential of someone else (your older brother for instance) to buy age restricted material on line. Currently, we use PIN codes to prevent this. But this is weak if your brother is happy to share his PIN with you. Goal of this project is to study ways to bind credentials to individuals, and to think of new ways to make this binding stronger.
- Privacy by design
- Investigate the concept of privacy design patterns: what should such a pattern contain, what patterns have been described so far, for which privacy design problems are design patterns mostly missing. Define a your own set of privacy design patterns.
I teach the following courses
Both courses are part of the
TRU/e security master.
I, and other people in our group, sometimes teach a
cryptography and security lab
for high-school students.
