Abstract

Broadcast mechanism is prevalent in many forms of electronic networks. Modeling broadcast protocols succinctly and reasoning about how secure these protocols are is gaining importance as society increasingly comes to depend on a wide variety of electronic communications. In this work we present a modified ambient calculus where the nature of communication is broadcast within domains. We allow reconfigurable configurations of communication domains, access restrictions to domains and the capability of modeling cryptographic communication protocols in broadcast scenarios.
