Describing and reasoning about asynchronous distributed systems is often a difficult and error prone task. In this paper we experiment the Input/Output Automata framework as a tool to describe and reason about cryptographic protocols running in an asynchronous distributed system. We examine a simple certified email protocol [5], give its formalization using the IOA model, and prove that some security properties are satisfied during the execution of the protocol.
