Fairplay project
The Fairplay system allows any distributed protocol to be specified as if a trusted external party exists. It implements the specified protocol securely as if the trusted party existed, but without relying on any such party in reality but rather on provably secure cryptographic "secure function evaluation" protocols.

Functional Encryption for Regular Languages
We provide a functional encryption system that supports functionality for regular languages. In our system a secret key is associated with a Deterministic Finite Automata (DFA) M. A ciphertext, CT, encrypts a message m and is associated with an arbitrary length string w. A user is able to decrypt the ciphertext CT if and only if the DFA M associated with his private key accepts the string w.

Interesting result, though the requirement for stateful keys seems not worthwhile.
