Formalization and co-simulation of attacks on cyber-physical systems

Abstract

This paper presents a methodology for the formal modeling of security attacks on cyber-physical systems, and the analysis of their effects on the system using logic theories. We consider attacks only on sensors and actuators. A simulated attack can be triggered internally by the simulation algorithm or interactively by the user, and the effect of the attack is a set of assignments to the variables defined in the Controller. The global effects of the attacks are studied by injecting attacks in the system model and co-simulating the overall system, including the system dynamics and the control part. Interesting properties of the behaviour of the system under attack can also be formally proved by theorem proving. The INTO-CPS framework has been used for co-simulation, and the methodology is applied to the Line follower robot case study of the INTO-CPS project. The theorem prover of PVS has been used for deriving formal proofs of invariants of the system under attack.

Model of Systematization of Classifiers of Destructive and Constructive Events in the Digital Space

“…A. 3 , Seleznev V. M. 4 The aim of the work is to develop a generalized formal model for systematizing the main classifiers of destructive and constructive events in the infrastructure of the digital space of a sovereign state to organize the autonomy of an intelligent agent in the form of a data facet.…”

В результате, можно отметить совершенствование существующих моделей злоумышленник / защитник для обучения кибербезопасности интеллектуальных моделей, в том числе и моделей противоборства социальной инженерии [4].…”

Relational Analysis of Sensor Attacks on Cyber-Physical Systems

“…Bernardeschi et al [46] introduce a framework to analyze the effects of attacks on sensors and actuators. Controllers of systems are specified using the formalism PVS [47].…”
