Conformance Relations and Hyperproperties for Doping Detection in Time and Space [article]

Sebastian Biewer, Rayna Dimitrova, Michael Fries, Maciej Gazda, Thomas Heinze, Holger Hermanns, Mohammad Reza Mousavi
2022 arXiv   pre-print
We present a novel and generalised notion of doping cleanness for cyber-physical systems that allows for perturbing the inputs and observing the perturbed outputs both in the time- and value-domains.  ...  We show that our generalised definitions are essential in a data-driven method for doping detection and apply our definitions to a case study concerning diesel emission tests.  ...  In the above example, we demonstrated that not accounting for timing disturbances when relating input trajectories can result in false negatives in doping detection.  ...

Doping Tests for Cyber-Physical Systems [article]

Sebastian Biewer and Pedro D'Argenio and Holger Hermanns
2019 arXiv   pre-print
The work presented in this paper builds on existing definitions of software doping and lays the theoretical foundations for conducting software doping tests, so as to enable attacking evil manufacturers  ...  Doped software is significantly different from buggy or insecure software and hence it is not possible to use classical verification and testing techniques to discover and mitigate software doping.  ...  Due to lack of space, we cannot present the concrete Ω case andIn for these examples. Discussion Related Work.  ...

Statistical Verification of Hyperproperties for Cyber-Physical System [article]

Yu Wang, Mojtaba Zarei, Borzoo Bonakdarpour, Miroslav Pajic
2019 arXiv   pre-print
In this work, we focus on verifying probabilistic hyperproperties for CPS.  ...  Examples include probabilistic fairness and sensitivity to modeling errors (i.e., parameters changes) for real-valued signals. These requirements can only be specified by hyperproperties.  ...  The probabilistic hyperproperties related to P 2 HIOA, as the one discussed in Sections 1 and 4, will be statistically verified on this PUS.  ...
