Abstract

We address the problem of message authentication using the pi-calculus, which has been given an operational semantics that provides each sequential process of a system with its own local space of names. We exploit here that semantics and its localized names to guarantee by construction that a message has been generated by a given entity. Therefore, our proposal can be seen as a reference for the analysis of "real" protocols. As an example, we study the way authentication is ensured by encrypting messages in the pi-calculus.
