	Title	Advanced techniques for safety analysis applied to the gas turbine control system of Icaro co generative plant			Type	Conference Article
	Year	2001	Publication	X Convegno Tecnologie e Sistemi Energetici Complessi	Abbreviated Journal
	Volume		Issue		Pages	339-350
	Keywords
	Abstract	The paper describes two complementary and integrable approaches, a probabilistic one and a deterministic one, based on classic and advanced modelling techniques for safety analysis of complex computer based systems. The probabilistic approach is based on classical and innovative probabilistic analysis methods. The deterministic approach is based on formal verification methods. Such approaches are applied to the gas turbine control system of ICARO co generative plant, in operation at ENEA CR Casaccia. The main difference between the two approaches, behind the underlining different theories, is that the probabilistic one addresses the control system by itself, as the set of sensors, processing units and actuators, while the deterministic one also includes the behaviour of the equipment under control which interacts with the control system. The final aim of the research, documented in this paper, is to explore an innovative method which put the probabilistic and deterministic approaches in a strong relation to overcome the drawbacks of their isolated, selective and fragmented use which can lead to inconsistencies in the evaluation results.

	Title	Risk analysis via heterogeneous models of SCADA interconnecting Power Grids and Telco networks			Type	Conference Article
	Year	2009	Publication	Proceedings of Fourth International Conference on Risks and Security of Internet and Systems (CRiSIS)	Abbreviated Journal
	Volume		Issue		Pages	90-97
	Keywords
	Abstract	The automation of power grids by means of supervisory control and data acquisition (SCADA) systems has led to an improvement of power grid operations and functionalities but also to pervasive cyber interdependencies between power grids and telecommunication networks. Many power grid services are increasingly depending upon the adequate functionality of SCADA system which in turn strictly depends on the adequate functionality of its communication infrastructure. We propose to tackle the SCADA risk analysis by means of different and heterogeneous modeling techniques and software tools. We demonstrate the applicability of our approach through a case study on an actual SCADA system for an electrical power distribution grid. The modeling techniques we discuss aim at providing a probabilistic dependability analysis, followed by a worst case analysis in presence of malicious attacks and a real-time performance evaluation.

	Title	Disk Based Software Verification via Bounded Model Checking			Type	Conference Article
	Year	2007	Publication	APSEC '07: Proceedings of the 14th Asia-Pacific Software Engineering Conference	Abbreviated Journal
	Volume		Issue		Pages	358-365
	Keywords
	Abstract	One of the most successful approach to automatic software verification is SAT based bounded model checking (BMC). One of the main factors limiting the size of programs that can be automatically verified via BMC is the huge number of clauses that the backend SAT solver has to process. In fact, because of this, the SAT solver may easily run out of RAM. We present two disk based algorithms that can considerably decrease the number of clauses that a BMC backend SAT solver has to process in RAM. Our experimental results show that using our disk based algorithms we can automatically verify programs that are out of reach for RAM based BMC.

	Title	Automatic Analysis of a Safety Critical Tele Control System			Type	Conference Article
	Year	2005	Publication	24th International Conference on: Computer Safety, Reliability, and Security (SAFECOMP)	Abbreviated Journal
	Volume		Issue		Pages	94-107
	Keywords
	Abstract	We show how the Mur$\varphi$ model checker can be used to automatically carry out safety analysis of a quite complex hybrid system tele-controlling vehicles traffic inside a safety critical transport infrastructure such as a long bridge or a tunnel. We present the Mur$\varphi$ model we developed towards this end as well as the experimental results we obtained by running the Mur$\varphi$ verifier on our model. Our experimental results show that the approach presented here can be used to verify safety of critical dimensioning parameters (e.g. bandwidth) of the telecommunication network embedded in a safety critical system.

	Title	Model Checking Satellite Operational Procedures			Type	Conference Article
	Year	2011	Publication	DAta Systems In Aerospace (DASIA), Org. EuroSpace, Canadian Space Agency, CNES, ESA, EUMETSAT. San Anton, Malta, EuroSpace.	Abbreviated Journal
	Volume		Issue		Pages
	Keywords
	Abstract	We present a model checking approach for the automatic verification of satellite operational procedures (OPs). Building a model for a complex system as a satellite is a hard task. We overcome this obstruction by using a suitable simulator (SIMSAT) for the satellite. Our approach aims at improving OP quality assurance by automatic exhaustive exploration of all possible simulation scenarios. Moreover, our solution decreases OP verification costs by using a model checker (CMurphi) to automatically drive the simulator. We model OPs as user-executed programs observing the simulator telemetries and sending telecommands to the simulator. In order to assess feasibility of our approach we present experimental results on a simple meaningful scenario. Our results show that we can save up to 90% of verification time.
