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 ... 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-

WebThe Cryptographic Protocol Shapes Analyzer (CPSA) [19,32,26] is an open-source tool for automated formal analysis of cryptographic protocols. The tool takes as input a model of a cryptographic protocol and a set of initial assump-tions called the \point of view," and attempts to calculate a set of minimal, essentially di erent executions of the ... WebFeb 28, 2014 · All these tools work in the "symbolic" model often referred to as the Dolev-Yao model: they assume that the underlying cryptographic primitives (encryption schemes, signature schemes) are perfect and analyze all possible interactions between an active network attacker and the protocol.
