The life-cycle development of critical systems follows mainly a V-cycle process overlapped with proofs and/or verification techniques. At the first development stage, a critical system must be, precisely, and as completely as possible described. Thus, it is recommended to use a graphical modeling language standard such as the Unified Modeling Language (UML) and the Object Constraint Language (OCL), to which both customers and developers could contribute. Then, the graphical design with its formal specification (requirements) is mapped into a complete formal development environment, using an MDE (Model-driven engineering) approach. The formal environment has to assess the development until the generation of a secure code. In this context, we propose a life-cycle development approach that combines UML/OCL and the FoCaLiZe formal environment for the secure development of critical systems. The proposed approach ensures essential development constraints such as strict boundaries and traceability between development phases. It also ensures a secure maintenance phase using partial transformation techniques from UML/OCL to FoCaLiZe. The latter enhances the transformation from UML/OCL into FoCaLiZe to support incremental development and assist developers in correcting modeling errors. The proposed approach is mostly dedicated to secure and maintainable lifecycle development processes of critical systems. The formal environment assesses the development process until the generation of a secure code. To illustrate the proposed approach, we present the stages of development of a constrained system controlling military objects. The development of this system uses the iterative, incremental, and maintainability stages as described by the development approach, until the generation of secure code.

“…In order to solve specific problems of specific systems, researchers have combined Event-B with multiple methods. To analyze and model the behavior of the system formally, Kenza et al combined UML and Event-B [22]. In their work, UML is used to model the system from an informal specification.…”

An Integrated Formal Method Combining Labeled Transition System and Event-B for System Model Refinement

Formal modeling and verification of a concurrent system is an essential means to ensure the security and reliability of the system. However, at present, there is no single formal method that can fully meet the modeling and verification requirements of concurrent systems. In this paper, we propose an integrated formal method that utilizes both event-based method Event-B and state-based formalism LTS to address this problem. We first analyze the difference and connection between Event-B and LTS in building system models and then propose to use the graphical front-end iUML-B of Event-B to obtain a unified representation with LTS so as to take their advantages in the integrated method. Finally, we carry out a case study to demonstrate the practicality of the proposed method. The case study shows that our method effectively models and verifies the various properties of the system, and to a large extent makes up for the shortcomings of a single formal method in the process of system modeling and verification.
