Abstract

Noninterference properties for the analysis of secure information flow are proposed in the setting of a process algebra modeling some Linda coordination primitives (asynchronous communication and read operation). To this end, relaxed definitions of equivalence are introduced that take into consideration the observational power of the external observer. The resulting taxonomy is compared with corresponding security definitions for synchronous communication models. As a result, we emphasize how the proposed coordination model affects the expressive power of some noninterference properties, by giving a new intuition to the relative merits.
