Cryptographic protocol shapes analyzer
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 ...

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 ... WebWe analyze the Secure Remote Password (SRP) protocol for structural weaknesses using the Cryptographic Protocol Shapes Analyzer (CPSA) in the first formal analysis of SRP (specifically, Version 3). SRP is a widely deployed Password Authenticated Key Exchange (PAKE) protocol used in 1Password, iCloud Keychain, and other products.
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]. 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.
