In this work, we address the formalisation of symmetric nets, a subclass of coloured Petri nets, refinement in COQ. We first provide a formalisation of the net models, and of thei...
We automatically verify Back's atomicity refinement law and a classical data refinement law for action systems. Our novel approach mechanises a refinement calculus based on K...
Abstract. In the area of networks, a common method to enforce a security policy expressed in a high-level language is based on an ad-hoc and manual rewriting process [24]. We argue...
Petri nets are a formalism for modelling and validating critical systems. Generally, the approach to specification starts from an abstract view of the system under study. Once val...
