Secure Communication in Cyber-Physical Systems

Abstract

The paper considers a new design methodology for organization of reliable and secure data transfer
environment in cyber-physical systems, which contain microcontroller-based devices. The key
idea of the design methodology is in providing of most rational solution to improve the data transfer
environment according to functional and non-functional requirements and limitations to security
and reliability. This solution will became trusted only after verification process checking its correctness
and compatibility. If a cyber-physical system is dynamic and contains various mobile devices,
the design process of such system will determine additional requirements and limitations to its data
transfer environment. The application of the design methodology is presented for I2C network of
Arduino-based devices that are used for interaction with external event sources in the Integrated
Cyber-Physical Security System.
