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

Abstract

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.
