We introduce a new system of trust analysis for concurrent and distributed systems using the π-calculus[13, 14, 15] as a modelling tool. A Type system using boolean annotations g...
In a service-oriented architecture, systems communicate by exchanging messages. In this work, we propose a formal model based on OCL-constrained UML Class diagrams and a methodolo...
Specifying and managing access control policies is a challenging problem. We propose to develop formal verification techniques for access control policies to improve the current s...

In this paper we develop a methodology for treating the problem of scheduling partially-ordered tasks on parallel machines. Our framework is based on the timed automaton model, or...
We present an algorithm based on temporal-epistemic model checking combined with fault injection to analyse automatically the diagnosability of faults by agents in the system. We d...
