Abstract

The use of the Internet raises serious behavioural issues regarding, for example, security and the interaction among agents that may travel across links. Model-building such interactive systems is one of the biggest current challenges in computer science. A general model, action calculi, has been introduced by Robin Milner to unify the various emerging disciplines of interactive behaviour. In this paper action calculi is used as an abstraction of interactive systems and information flow security properties of such systems are studied. At first an information flow analysis for static action calculi is presented to predict how data will flow both along and inside actions and its correctness is proved; Next basing on the result of the analysis information security properties of both static and dynamic action calculi are discussed; Finally a general relationship are established between the static notation of information flow security and the dynamic one.
