Safety and security aware framework for the development of feedback control systems

摘要

The need to address safety and security related aspects at an early stage of development of feedback control systems (FCS) has been identified as vital for the optimisation of the development process of military land systems. These systems often include network enabled capability (NEC) allowing the use of electronics architectures to integrate different sub-systems. However, this increased integration capability is associated with magnified safety risks and compromise from cyber attacks [4]. This paper discusses how the process of developing FCS for military land systems could benefit from the use of a framework that addresses safety and security issues at the system modelling level. The core part of the suggested framework consists of a Simulink model to be used by design engineers as a blueprint for the development of a modular FCS that are expected to feature a modular architecture with dedicated sub-modules for the processing of data related to safety and security aspects. Since the FCS developed through the use of framework features a modular architecture, the anticipated cost incurred in the design of the associated modular safety case is expected to be reduced, leading to an overall reduction of the cost of the re-certification process [1].
