Safety and security risk assessment in cyber‐physical systems

Cyberphysical systems security applied to telesurgical robotics

a r t i c l e i n f o Researchers in telesurgical robotics and security collaborated to develop the Secure ITP, a security enhancement to the Interoperable Telesurgery Protocol (ITP). The ITP defines the structure for communication between telesurgery robots and controllers and has been adopted and tested by fourteen research groups in telesurgical robotics. The Secure ITP uses open source soft...

Formalized Risk Assessment for Safety and Security

The manifold interactions between safety and security aspects in embedded systems makes it plausible to handle safety and security risks in a unified way. The paper develops a corresponding risk measure in the context of discrete event systems (DEVS). The chosen approach is based on a simulation of system dynamics, which allows risk assessments even in cases with stepwise system degradation, ca...

Contamination and Risk Assessment of Total Aflatoxin in Iranian Rice in Various Food Security Regions

Background and Objectives: Aflatoxin is one of the most important and common toxins in high consumption foods such as rice, which can threaten health of the consumers. In this study, risk of total aflatoxin based on its exposure levels and adverse effects was assessed in Iranian rice.  Materials & Methods: This study was carried out on total aflatoxin in 60 national rice samples collected base...

Beyond the Cloud: Cyberphysical Systems

C louds offer a novel way to revitalize the seemingly archaic concept of time-sharing. Rather than relying on fixed mainframes, clouds thrive in the Internet. Clouds offer impressive efficiencies, unprecedented collaboration opportunities, and economies of scale for all manner of networked users. Yet cloud server farms have enormously costly power consumption footprints and require massive data...
