Call for Papers  

Cyber-Physical Systems (CPS) consist of large-scale interconnected systems of heterogeneous components interacting with their physical environments. There are a multitude of CPS devices and applications being deployed to serve critical functions in our lives. The security of CPS becomes extremely important. This workshop will provide a platform for professionals from academia, government, and industry to discuss how to address the increasing security challenges facing CPS. Besides invited talks, we also seek novel submissions describing theoretical and practical security solutions to CPS. Papers that are pertinent to the security of embedded systems, SCADA, smart grid, and critical infrastructure networks are all welcome, especially in the domains of energy and transportation. Topics of interest include, but are not limited to:

  • Adaptive attack mitigation for CPS
  • Authentication and access control for CPS
  • Availability, recovery and auditing for CPS
  • Data security and privacy for CPS
  • Embedded systems security
  • EV charging system security
  • Intrusion detection for CPS
  • IoT security
  • Key management in CPS

Submission Instructions

Submitted papers must not substantially overlap papers that have been published or that are simultaneously submitted to a journal or a conference with proceedings. All submissions should be appropriately anonymized (i.e., papers should not contain author names or affiliations, or obvious citations). Submissions must be in double-column ACM SIG Proceedings format, and should not exceed 12 pages. Position papers and short papers of 5 pages describing the work in progress are also welcome.

Risk Assessment of Cyber Access to Physical Infrastructure in Cyber-Physical Systems
Prof. David M. Nicol (University of Illinois at Urbana-Champaign, USA)

Networks of computational devices are used increasingly to construct cyber-physical systems (CPS) that monitor and control significant physical infrastructures such as the electric grid, water supply systems, gas pipelines, maritime systems, etc. Reliance on these devices increases the means by which failure and/or malfeasance can adversely impact the integrity and operations of the infrastructure. A pressing question then asks how one can assess the risk to the infrastructure -- or to the services it provides -- through compromise of the cyber component of a CPS. This talk describes a method of coupling a quantitative analysis of how attackers can reach the physical system through compromising a cyber-network with a quantitative analysis of the impacts that cyber-based attacks may have on the physical system. The combined analysis lays a basis for risk assessment of cyber-physical systems to cyber-attack

David M. Nicol is the Franklin W. Woeltge Professor of Electrical and Computer Engineering at the University of Illinois at Urbana-Champaign (UIUC), and Director of the Information Trust Institute (iti.illinois.edu). He is PI for two recently awarded national centers for infrastructure resilience: the DHS-funded Critical Infrastructure Reliance Institute (ciri.illinois.edu), and the DoE funded Cyber Resilient Energy Delivery Consortium (cred-c.org). Prior to joining UIUC in 2003, he served on the faculties of the Computer Science Department at Dartmouth College (1996-2003), and before that the College of William and Mary (1987-1996). His research interests include trust analysis of networks and software, analytic modeling, and parallelized discrete-event simulation, research which has lead to the founding of startup company Network Perception, and election as Fellow of the IEEE and Fellow of the ACM. He is the inaugural recipient of the ACM SIGSIM Outstanding Contributions award, and co-author of the widely used undergraduate textbook "Discrete-Event Systems Simulation". He received the M.S. (1983) and Ph.D. (1985) degrees in computer science from the University of Virginia, and the B.A. degree in mathematics (1979) from Carleton College.

N-Version Obfuscation
Prof. Michael R. Lyu (Chinese University of Hong Kong, China)

Software plays a key role in cyber-physical systems. Once their software integrity has been violated, cyber-physical systems would suffer security issues (e.g., system failures, backdoor attacks) because of executing unexpected instructions. Existing software integrity protection approaches for cyber-physical systems can be classified into circuit-assisted approach, and pure software approach. A circuit-assisted approach is known to be more secure, but it does not have general applicability. In fact, more and more cyber-physical systems are built upon open hardware architectures and operating systems, such as smartphones. These systems cannot rely on specific hardware to provide security due to usability constraints. Pure software approach is thus desired for these application scenarios. Obfuscation and self-checksumming are the two major tamper-resistant approaches that do not rely on circuits. However, none of them can achieve theoretically tamper-proof, as Collberg said, "Given enough time, effort and determination, a competent programmer will always be able to reverse engineer any application." Recent investigations have made much theoretical progress that supports Collberg's claim, e.g., Barak et al. have proved that obfuscation cannot achieve black-box security for some programs; Appel has proved that the hardness of de-obfuscation is NP-easy. Their results discourage researchers towards finding novel trustworthy obfuscation approaches, whose security strength can be guaranteed or quantified.

In this talk, we will first discuss several software threats faced by cyber-physical systems, and then introduce a new tamper-resistance idea, namely N-version obfuscation (NVO). Rather than proposing new tricks against tampering attack, NVO focuses on impeding the replication of software tampering via program diversification, and thus poses a scalability barrier against the attacks. We propose a general framework for NVO, together with the associated mechanism, for a candidate solution to achieve integrity of cyber-physical systems. Implementation considerations, together with some preliminary results, will also be presented.
