Design methodologies for securing cyber-physical systems

Abstract

Cyber-Physical Systems (CPS) are in most cases safety-and mission-critical. Standard design techniques used for securing embedded systems are not suitable for CPS due to the restricted computation and communication budget available in the latter. In addition, the sensitivity of sensed data and the presence of actuation components further increase the security requirements of CPS. To address these issues, it is necessary to provide new design methods in which security is considered from the beginning of the whole design flow and addressed in a holistic way. In this paper, we focus on the design of secure CPS as part of the complete CPS design process, and provide insights into new requirements on platform-aware design of control components, design methodologies and architectures posed by CPS design. We start by discussing methods for the multi-disciplinary modeling, simulation, tools, and software synthesis challenges for CPS. We also present a framework for design of secure control systems for CPS, while taking into account properties of the underlying computation and communication platforms. Finally, we describe the security challenges in the computing hardware that is used in CPS.

Cybercrime and Risks for Cyber Physical Systems: A Review

“…[17], proposed a unified framework that consist of three orthogonal coordinates namely: (1) from the security perspective, the authors followed the well-known taxonomy of threats, vulnerabilities, attacks and controls. (2) from the CPS components perspective, the authors focused on cyber, physical and cyber-physical components: (3) from the CPS systems perspective, the authors explored general CPS features as well as the representative systems such as smart grids, medical CPS and smart cars. The model was both abstract to capture the general interactions of a CPS application and specific to capture any details when needed.…”

“…The authors discussed a multidisciplinary modeling, simulation, tools, and software synthesis challenges for CPS. [2], proposed a security aware model based on design in methods to assess the security of CPS within four types of architecture level attacks. The group exploits the observations by identifying and fixing problems at early stage of the system development is economically beneficial.…”

Strategies to Design Signals to Spoof Kalman Filter

“…Of particular concern is their vulnerability to signal spoofing attacks [3]. As a result, many researchers are designing algorithms that enable an observer to detect and mitigate signal spoofing attacks (e.g., [4]- [9]). We study the problem from the opposite (i.e., the attacker's) point-of-view.…”

Security and Privacy Challenges in Cyber-Physical Systems

“…They also discuss the importance of developing new adversary models for CPS. In [11], the authors suggest a security design for CPS that considers specific common characteristics of CPSs, such as the CPS environment, real-time requirements, uncertainty and geographic distribution. Further, [11] indicates that taking care of security in CPSs should start at the very beginning of the designing phase by developing new appropriate security tools that meet the specific system requirements.…”
