Safety and Security-driven Design of Networked Embedded Systems

The paper presents a safety and security-driven approach to embedded system design for an industrial class of Internet-based applications. It discusses an integrated networking framework stemming from the IEEE 1451.1 smart transducer interface standard, which is an object-based networking model supporting client-server and publish-subscribe communication patterns in group messaging, and from the IP multicast communication, all together mediating safe and secure access to smart sensors through Internet. The case study demonstrates how clients can access groups of wireless smart pressure and temperature sensors and valves effectively through Internet using developed system architecture while respecting prescribed requirements for application dependent safety and security.
