Modelling, verification, and formal analysis of security properties in a P2P system

Sam B. Sanjabi, Franck Pommereau
2010 2010 International Symposium on Collaborative Technologies and Systems  
We formally modelled the salient behavior of the actual system using ABCD, a high level specification language with a coloured Petri net semantics, which allowed the execution states of the system to be  ...  Furthermore, since the implementation is also a formal model, we have been able to show that any execution of the model satisfies certain desirable security properties once these flaws are repaired.  ...  If successful, we will have a system that was designed, model checked, simulated, and formally analyzed around the exact same specification, strengthening the ties between many aspects of the software  ...

A UML and Colored Petri Nets Integrated Modeling and Analysis Approach using Graph Transformation

Elhillali Kerkouche, Algeria Allaoua Chaoui, El Bay Bourennane, Ouassila Labbani
2010 Journal of Object Technology  
In this paper, we propose an approach for transforming UML statechart and collaboration diagrams to Colored Petri net models.  ...  This transformation aims to bridge the gap between informal notation (UML diagrams) and more formal notation (Colored Petri net models) for analysis purposes.  ...  Using our approach, the modellers specify the dynamics of a system by means of a set of statechart diagrams and collaboration diagram.  ...

Towards an Integrated Graph Based Semantics for UML

Martin Gogolla, Paul Ziemann, Sabine Kuske
2003 Electronical Notes in Theoretical Computer Science  
For UML models consisting of a class diagram and particular state diagrams, a graph transformation system can be defined.  ...  Recently, we proposed an integrated formal semantics based on graph transformation for central aspects of UML class, object and state diagrams.  ...  UML collaboration diagrams. These derivations are the formal counterpart of the diagrams and can help to confirm or to decrease the modeler's belief in the model.  ...
