### Towards more efficient, usable and socially accepted file sharing
with anonymity/deniability

This topic has captured my attention for quite some time now. So far the paper on breaking anonymity by learning a unique hitting set has appeared in the proceedings of CSR'09 (see publications page), the paper on Network Information Systems for Anonymity Networks will appear at CCS'09. My PhD thesis "World Libraries - Towards Efficiently Sharing Large Data Volumes in Open Untrusted Environments while Preserving Privacy" will be published soon.
### Exact algorithms for hard problems

All the papers on exact algorithms for hard problems that I have been
involved with in this group are neatly itemized
on Daniel Mölle's Homepage. Most of them
should also be available on
our publications page.
### Interactive Theorem Proving with Isabelle/Isar

Formal Integration Theory, with an
application to probabilistic algorithms.

These are Isabelle/Isar theory texts. Beware, the main theory needs HOL/Complex
images, the example even HOL4ExtraProb converted HOL4 sources from
Sebastian
Skalberg's import tool.
A large part of these theories is available in a more up-to-date form
on AFP.
