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. WebCryptographic protocol analysis Crypto protocol analysis tools usually apply some restrictions. Do not explore all elements from the set tr(Sys(Q)). Protocols are not actually verified in the full system Sys but rather in a subset of the behaviors. Subsets can be defined by using a Scenario. A Scenario is a multi-set of processes. S: the set of all …
