ion; Counter-Example Guided Abstraction Refinement; symmetry; . . . while others are hand-crafted, such as cut-point, counter-abstraction, or data independence. By construction, the verification objective (the root claim) is valid when all the rules instances in the argument are sound. We can back the soundness of rules like (split) and (abstraction) by reasoning on the semantics of the models. This is not always the case and this is one of the motivation for adding a justification to every rule instance. Next, we give two examples of “evidence-based rules”, (scope) and (formalization), which are rules whose soundness is supported only by subject matter expertise. (scope) 〈Hs ;Ms ;P〉 〈H ;M ;P〉 (formalize) 〈H ;M ;P〉

Web Service Choreography Verification Using Z Formal Specification
Web Service Choreography Description Language (WS-CDL) describes and orchestrates the services interactions among multiple participants. WS-CDL verification is essential since the interactions would lead to mismatches. Existing works verify the messages ordering, the flow of messages, and the expected results from collaborations. In this paper, we present a Z specification of WS-CDL. Besides ve...
متن کاملReachability checking in complex and concurrent software systems using intelligent search methods
Software system verification is an efficient technique for ensuring the correctness of a software product, especially in safety-critical systems in which a small bug may have disastrous consequences. The goal of software verification is to ensure that the product fulfills the requirements. Studies show that the cost of finding and fixing errors in design time is less than finding and fixing the...
متن کاملSatisfaction Meets Practice and Confidence
The industrial application of formal methods and in particular of software verification tools, e.g. based on satisfiability checking and symbolic computation as being in the main focus of the SC network, necessitates two main requirements. The methods and tools, first, need to actually aim at the problem class that occur in practice and, second, have to guarantee a high level of confidence. In ...

Verifying sensor network security protocol implementations using testing/simulation might leave some flaws undetected. Formal verification techniques have been very successful in detecting faults in security protocol specifications; however, they generally require building a formal description (model) of the protocol. Building accurate models is hard, thus hindering the application of formal ve...
متن کاملModeling and Evaluation of Stochastic Discrete-Event Systems with RayLang Formalism
In recent years, formal methods have been used as an important tool for performance evaluation and verification of a wide range of systems. In the view points of engineers and practitioners, however, there are still some major difficulties in using formal methods. In this paper, we introduce a new formal modeling language to fill the gaps between object-oriented programming languages (OOPLs) us...
