Modeling and analyzing information integrity in safety critical systems

Abstract

Preserving information integrity represent an urgent need for safety critical systems, where depending on incorrect or inconsistent information may leads to disasters. Typically, information integrity is a problem handled at technical level (e.g., checksumming). However, information integrity has to be analyzed in the social-technical context of the system, since information integrity related problems might manifest themselves in the business processes and actors interactions. In this paper, we propose an extended version of i*/ secure Tropos modeling languages to capture information integrity requirements. We illustrate the Datalog formalization of the proposed concepts and analysis techniques to support the analyst in the verification of integrity related properties. Air Traffic Management (ATM) case study is used throughout the paper.
