Security framework for industrial collaborative robotic cyber-physical systems

Abstract

The paper introduces a security framework for the application of human-robot collaboration in a futuristic industrial cyber-physical system (CPS) context of industry 4.0. The basic elements and functional requirements of a secure collaborative robotic cyber-physical system are explained and then the cyber-attack modes are discussed in the context of collaborative CPS whereas a defense mechanism strategy is proposed for such a complex system. The cyber-attacks are categorized according to the extent on controllability and the possible effects on the performance and efficiency of such CPS. The paper also describes the severity and categorization of such cyber-attacks and the causal effect on the human worker safety during human-robot collaboration. Attacks in three dimensions of availability, authentication and confidentiality are proposed as the basis of a consolidated mitigation plan. We propose a security framework based on a two-pronged strategy where the impact of this methodology is demonstrated on a teleoperation benchmark (NeCS-Car). The mitigation strategy includes enhanced data security at important interconnected adaptor nodes and development of an intelligent module that employs a concept similar to system health monitoring and reconfiguration.

A Novel Model Representation Framework for Cooperative Intelligent Transport Systems

“…Based on the classification of C-ITS components, transferred data and its application possibilities it can be seen that C-ITS can provide a common framework to harmonize the operation of different system components to support a safer, a more secured (Khalid et al, 2018), a more efficient and a more reliable transport service for road users.

Proceedings of the 29th European Safety and Reliability Conference (ESREL)

“…Despite the fact that some regulations, technical specifications, technical reports and researchers are trying to address the potential dangers of this type of robotics there are still many critical and dangerous aspects to consider. Security is closely associated with safety as both of these characteristics have to be addressed synchronously (Khalid et al 2018).…”

Digital Manufacturing Tools in the Simulation of Collaborative Robots: Towards Industry 4.0

“…The problem could be treated as a flow shop scheduling problem. Khalid et al (2018) explored in their work the risk of cyber-attacks in cyber physical collaborative operations. The paper introduced a security framework for the application of human-robot collaboration in a futuristic industrial cyber-physical system (CPS) context of industry 4.0.…”
