OnTrack: Reflecting on domain specific formal methods for railway designs

OnTrack is a tool that supports workflows for railway verification that has been implemented using model driven engineering frameworks. Starting with graphical scheme plans and finishing with automatically generated formal models set-up for verification, OnTrack allows railway engineers to interact with verification procedures through encapsulating formal methods. OnTrack is grounded on a domain specification language (DSL) capturing scheme plans and supports generation of various formal models using model transformations. In this paper, we detail the role model driven engineering takes within OnTrack and reflect on the use of model driven engineering concepts for developing domain specific formal methods toolsets

Formal Methods for the Verification of Safety Critical Applications using SPIN Model Checker

Security over the years has been a major concern for the organizations and companies.With the emergence of smart cards, industry has become more interested in methodologies which are used to establish the correctness and security of the applications developed with the acceptance of the use of smart cards in such domains.This paper provides a general introduction to the state-of-the-art of formal methods for the development of safety-critical systems. The idea is to combine two program verification approaches: the functional verification at the source code level and the verification of high level properties on a formal model built from the program and its specification. One of the important security systems in building security is door access control. The door access control is a physical security that assures the security of a building by limiting access to the building to specific people and by keeping records of such entries.In thispaper we employ a model checking method to verify the functional aspects of the smartcard operated door lock system which authenticates each person entering the building.PROMELA model for the proposed system Is presented.
