Abstracting cryptographic protocols with tree automata [PDF]

Science of Computer Programming, 1999
AbstractCryptographic protocols have so far been analyzed for the most part by means of testing (which does not yield proofs of secrecy) and theorem proving (costly). We propose a new approach, based on abstract interpretation and using regular tree languages. The abstraction we use seems fine-grained enough to be able to certify some protocols.
