WebThrough a case study of IETF protocols for the IoT, we illustrate the power of continuous verification by (i) discovering flaws in the protocols using the Cryptographic Protocol Shapes Analyzer (CPSA); (ii) identifying the corresponding fixes based on the feedback provided by CPSA; and (iii) demonstrating that verifiable models can be intuitive ... 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].
