“…Kim et al [18] discussed the safety issues regarding train collisions caused by train safety signals and studied the vulnerability of CPS safety and security. Wang et al [19] realized the optimization of safety systems and enhancement of security strategies by means of optimizing defensive resource allocation, their measurement increased the robustness of CPS. A detailed analysis work was reported by Wang et al [20] to discuss the difference and connection between functional safety and information security, they also proposed the concept of security integration and integrated lifecycle model, which gives a preliminary description of how to realize the security integration of intelligent manufacturing process.…”

This paper proposes a functional safety and information security protection mechanism based on blockchain technology. The design of the basic level and integration level blockchain structure of CPS distributed architecture and related functional safety and information security measures are introduced. An effective communication judgment mechanism based on functional safety error threshold is proposed, which is stored and judged by smart contract. And a refund transaction with a clock is proposed to ensure the effective execution of the functional safety error threshold mechanism. The article takes cyber physical machine tool system as an example to describe the SIL judgment method of CPS physical equipment and functional safety loop and combines SIL with fault diagnosis and risk protection. Finally, the rationality of our proposed mechanism is proved by information security, functional security, real-time and maintainability.

“…This is particularly true for cyber attacks, which are the focus of this work, since the majority of game-theoretic models assume that the defender moves first (e.g. designing a system, as in this work), and that the attacker moves after [9][10][11][12][13]. However, this means that an attacker can maximize the objective (of his/her malevolent act) and cyber attacks might be disguised from random failures, rendering the recovery difficult [14,15].…”

In this work, we consider diagnostics of cyber attacks in Cyber-Physical Systems (CPSs), based on data analytics. For the first time to authors knowledge, the performance of such diagnosis is quantified considering the possible failure of the human operator cognitive process in interpreting and understanding the diagnosis support tool outcomes. A Non-Parametric CUmulative SUM (NP-CUSUM) approach is used for datadriven diagnostic, and the cognitive process of the human operator who interprets its outputs is modelled by a Bayesian Belief Network (BBN). The overall framework is applied on the digital controller of the Advanced Lead-cooled Fast Reactor European Demonstrator (ALFRED).

“…In all cases of applications, CPSs have to guarantee high reliability standards with respect to hardware components stochastic failures that can result in accidental scenarios leading the system towards unacceptable consequences, as well to cyber components failures (Wang et al (2019)).…”

Cyber-Physical Systems (CPSs) are systems with tight integration and dependence between software and hardware parts, typically used as control systems and supervised by human operators. In this paper, we propose a multi-state model (commonly used to model the hardware degradation) to describe the aging of the cyber part of a CPS, where memory leakage is considered as the degradation process that leads to a service rate decrease, resulting in data jamming in the mission queue which, in turns, increases the memory request. The CPS is blocked and significantly increases the control delay when the amount of memory available cannot satisfy the demand of the mission queue. With control delay, the CPS may fail to control the system during transients: as an example, a typical Nuclear Power Plant (NPP) control rod system is taken as the CPS and its cyber degradation process modelled with the proposed multi-state degradation model. The unreliability of control rod system is quantified with respect to a transient of power step change, considering cyber degradation and hardware stochastic failure.
