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. WebA cryptographic protocol is a way to securely exchange data over a computer network. The data that is exchanged is encrypted. In general, these protocols consist of a way to …
