The management of the operations acting over distributed and virtual resources plays an important role for achieving the success of modern distributed applications. In this paper, we advocate a notion of resources as entities with their own local policies and containing their global interactive properties. We introduce a variant of π-calculus with primitives to declare, acquire and release reso...

We present a survey of the work on control-flow analysis carried on by the Venice Team during the Mefisto project. We study security issues, in particular information leakage detection, in the context of the Mobile Ambient calculus. We describe BANANA, a Java-based tool for ambient nesting analysis, by focussing on analysis accuracy and algorithmic optimizations.

We present a framework for specification and security analysis of communication protocols for mobile wireless networks. This setting introduces new challenges which are not being addressed by classical protocol analysis techniques. The main complication stems from the fact that the actions of intermediate nodes and their connectivity can no longer be abstracted into a single unstructured advers...

We report on a case study on control-flow analysis of business process models. We checked 735 industrial business process models from financial services, telecommunications and other domains. We investigated these models for soundness (absence of deadlock and lack of synchronization) using three different approaches: the business process verification tool Woflan, the Petri net model checker LoL...

We introduce a Control Flow Analysis for Brane Calculi. This verification technique allows properties regarding the behaviour of biological systems to be checked. This is an approximate technique that focusses on the static specification of a system, rather than on its dynamics, striving for effectiveness. Examples illustrate the approach.

We introduce a Control Flow Analysis, that statically approximates the dynamic behaviour of processes, expressed in the Beta-binders calculus and in an extended version of the calculus modelling static compartments. Our analysis of a system is able to describe the essential behaviour of each box, tracking all the possible bindings of variables, all the possible intraand inter-boxes communicatio...

We improve the precision of a previous Control Flow Analysis for Brane Calculi [4], by adding information on the context and introducing causality information on the membranes. This allows us to prove some biological properties on the behaviour of systems specified in Brane Calculi.

This paper deals with stabilization of a broad class of interconnected systems with a constrained control structure. It is assumed that an information flow matrix for the interconnected system is given. This matrix specifies which outputs of the system are available for constructing any input signal of the system. The notion of quotient overlapping fixed mode (QOFM) is introduced, and it is sho...
