WebThe Cryptographic Protocol Shapes Analyzer [24] (cpsa) is our program for automatically characterizing the possible executions of a protocol com- patible with a speci ed partial execution. It is grounded in strand space theory. Websentially diﬀerent shapes, the enumeration will terminate. From the shapes, we can then read oﬀ the answers to secrecy and authentication questions and observe other anomalies. Our software implementation of this method is called a Cryptographic Protocol Shapes Analyzer (cpsa). We use the strand space theory [8].
