We expound a method of analyzing cryptographic protocols using geometric logic and the Chase. Geometric logic is a formal system of logic comparable to first order logic, and the Chase is an algorithm which finds models for a given geometric logic theory. We use the Strand Space formalism as a model of protocol execution. Our work includes a rigorous translation of the Strand Space formalism, developed at MITRE, into geometric logic, a compiler that translates cryptographic protocols into geometric logic theories, and an algorithm for checking isomorphism between protocol executions in a special case in linear time.
