From CAMAC to Wireless Sensor Networks and Time-Triggered Systems and Beyond. Part I

J. Zalewski

Intern. Journal of Computing, Vol. 15, No. 2, pp. 92-106, 2016.

Abstract: The objective of this paper is to present a historical overview of design choices for data acquisition and control systems, from the first developments in CAMAC, through the evolution of their designs operating in VMEbus, Firewire and USB, to the latest developments concerning distributed systems using, in particular, wireless protocols and time-triggered architecture. First part of the overview is focused on connectivity aspects, including buses and interconnects, as well as their standardization. More sophisticated designs and a number of challenges are addressed in the second part, among them: bus performance, bus safety and security, and others.

A Framework for Measuring Security as a System Property in Cyberphysical Systems Information

J. Zalewski, I.A. Buckley, B. Czejdo, S. Drager, A.J. Kornecki, N. Subramanian

Information (Switzerland), Vol. 7, No. 2, p. 33, 2016.

Abstract: This paper addresses the challenge of measuring security, understood as a system property, of cyberphysical systems, in the category of similar properties, such as safety and reliability. First, it attempts to define precisely what security, as a system property, really is. Then, an application context is presented, in terms of an attack surface in cyberphysical systems. Contemporary approaches related to the principles of measuring software properties are also discussed, with emphasis on building models. These concepts are illustrated in several case studies, based on previous work of the authors, to conduct experimental security measurements.
