چکیده

This paper presents a method to include safety system conflicts into a fault tree analysis (FTA) with semantic extensions of fault events. The verification of the incoherent fault tree is done with an SMT-Solver. As an example a networked setup of medical devices for extracorporeal lung assist was analyzed. The method is developed as a basis for improved safety analysis of networked systems.

EFSMT: A Logical Framework for Cyber-Physical Systems

The design of cyber-physical systems is challenging in that it includes the analysis and synthesis of distributed and embedded real-time systems for controlling, often in a nonlinear way, the environment. We address this challenge with EFSMT, the exists-forall quantified first-order fragment of propositional combinations over constraints (including nonlinear arithmetic), as the logical framewor...

Addressing Safety and Security Contradictions in Cyber-Physical Systems

Modern cyber-physical systems are found in important domains such as automobiles, medical devices, building automation, avionics, etc.. Hence, they are increasingly prone to security violations. Often such vulnerabilities occur as a result of contradictory requirements between the safety/real-time properties and the security needs of the system. In this paper we propose a formal framework that ...

Quantified Bounded Model Checking for Rectangular Hybrid Automata

Satisfiability Modulo Theories (SMT) solvers have been successfully applied to solve many problems in formal verification such as bounded model checking (BMC) for many classes of systems from integrated circuits to cyber-physical systems (CPS). Typically, BMC is performed by checking satisfiability of a possibly long, but quantifier-free formula. However, BMC problems can naturally be encoded a...

IMHOTEP-SMT: A Satisfiability Modulo Theory Solver For Secure State Estimation∗

This paper presents IMHOTEP-SMT, a solver for the detection and mitigation of sensor attacks in cyber-physical systems. IMHOTEP-SMT receives as inputs a description of the physical system in the form of a linear difference equation, the system input (control) signal, and a set of output (sensor) measurements that can be noisy and corrupted by a malicious attacker. The output is the solution of ...
