Real-time Communication Security For Automation Networks

Abstract

A framework, device and method are disclosed for providing broadcast communication security over Ethernet within an automation system, wherein a security plug provides secure working of the automation system. The security plug can be implemented using ASIC/FPGA technology to provide compatibility with existing systems and an intuitive plug-and-play model. An exemplary system can address jitter-sensitivity by providing a real-time architecture, with minimal transmission latencies. The security plug can have separate security and communication modules that make provisions for protocol independent working of the security plug, within these networks. The method can include bootstrapping, secret key establishment and secure communication, for providing real-time guarantees.
