Webcpsa, our Cryptographic Protocol Shape Analyzer, implements the method. In searching for shapes, cpsa starts with some initial behavior, and discovers what shapes are compatible with it. Normally, the initial behavior is the point of view of one participant. The analysis reveals what the other principals must have done, given this participant ...

Weba Cryptographic Protocol Shapes Analyzer (cpsa). We use the strand space theory [10]. A skeleton represents regular (non-penetrator) behavior that might make up part of an execution, and a homo-morphism is an information-preserving map between skeletons. Skeletons are partially-ordered structures, like fragments of Lamport diagrams [13] or frag-
