Current work

All evil things you can do to a distributed system and what to do against this. This is motivated by trying to build
Dependable third parties and involves especially the ancient problem of
Byzantine Agreement as well as
funny algorithms for secret sharing and threshold cryptography
TCPA and related stuff. And, as opposed to most people with a strong opinion about it, I did read the Spec. Beginning to end. You'd be surprised about all the things not in there.
