Abstract

We present a platform that allows a protocol researcher to specify the sequence of games from an initial protocol to a protocol where the security property under consideration can be shown to hold using “conventional” means. Our tool represents the protocol in the form of a program dependency graph. A step in the sequence corresponds to replacing a local fragment in the current graph. The researcher interacts with the tool by pointing out the location of this fragment and choosing the applied transformation from a list. The tool guarantees the error-freeness of the sequence. By our knowledge, this is the first time where the aspects of user interaction have been seriously considered for a sequence-of-games-based protocol analyzer.
