Cryptographic protocol shapes analyzer
WebUsing the Cryptographic Protocol Shapes Analyzer (CPSA), we validate the security properties of the protocol through the novel use of CPSA’s state features to represent time. We also describe a small message space attack that highlights how assumptions made in protocol design can affect the security of a protocol in use, even for a protocol ... Weba Cryptographic Protocol Shape Analyzer cpsa. 1 Introduction The executions of cryptographic protocols frequently have a limited number of essentially different possible forms, which we call shapes. By enumerating these shapes, we may ascertain whether they all satisfy a security condition such as an authentication or confidentiality property.

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 ... WebThe Cryptographic Protocol Shapes Analyzer (CPSA) [25,32,38] 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 ...
