On the architecture and development life cycle of secure cyber-physical systems

Abstract

Cyber-physical systems are being confronted with an ever-increasing number of security threats from the complicated interactions and fusions between cyberspace and physical space. Integrating security-related activities into the early phases of the development life cycle is a monolithic and cost-effective solution for the development of security-critical cyber-physical systems. These activities often incorporate security mechanisms from different realms. We present a fine-grained design flow paradigm for security-critical and software-intensive cyber-physical systems. We provide a comprehensive survey on the domain-specific architectures, countermeasure techniques and security standards involved in the development life cycle of security-critical cyber-physical systems, and adapt these elements to the newly designed flow paradigm. Finally, we provide prospectives and future directions for improving the usability and security level of this design flow paradigm.
