Byzantine Consensus is Θ(n^2): The Dolev-Reischuk Bound is Tight even in Partial Synchrony!
Rachid Guerraoui, Jovan Komatovic, Pierre Philippe Civit, Manuel José Ribeiro Vidigueira, Vincent Gramoli, Seth Gilbert
The Dolev-Reischuk bound says that any deterministic Byzantine consensus protocol has (at least) quadratic communication complexity in the worst case. While it has been shown that the bound is tight in synchronous environments, it is still unknown whether ...
Dagstuhl Publishing2022Time-Synchronization Attacks against Critical Infrastructures and their Mitigation
Marguerite Marie Nathalie Delcourt
This work focuses on the security of critical infrastructures against time-synchronization attacks (TSA). A TSA can impact any network that relies on the dynamic analysis of data, by altering the time synchronization between its nodes. Such attacked networ ...
EPFL2021TDOA Source-Localization Technique Robust to Time-Synchronization Attacks
Jean-Yves Le Boudec, Marguerite Marie Nathalie Delcourt
In this paper, we focus on the localization of a passive source from time difference of arrival (TDOA) measurements. TDOA values are computed with respect to pairs of fixed sensors that are required to be accurately time-synchronized. This constitutes a we ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2021Time-Synchronization Attack Detection in Unbalanced Three-Phase Systems
Jean-Yves Le Boudec, Mario Paolone, Marguerite Marie Nathalie Delcourt, Gyorgy Miklos Dan
Phasor measurement units (PMU) rely on an accurate time-synchronization to phase-align the phasors and timestamp the voltage and current phasor measurements. Among the symmetrical components computed from the phasors in three-phase systems, the standard pr ...
2021The White Rabbit Time Synchronization Protocol for Synchrophasor Networks
Mario Paolone, Asja Derviskadic, Reza Razzaghi, Quentin Walger
Within the context of time dissemination techniques for power systems applications, the paper discusses the use of the White Rabbit (WR) protocol for synchrophasor networks. Specifically, the paper presents a Phasor Measurement Unit (PMU) integrating the W ...
2019Feasibility of Time Synchronization Attacks against PMU-based State-Estimation
Jean-Yves Le Boudec, Mario Paolone, Sergio Barreto Andrade, Marguerite Marie Nathalie Delcourt, Gyorgy Miklos Dan
The emerging measurement technology of phasor measurement units (PMUs) makes it possible to estimate the state of electrical grids in real-time, thus opening the way to new protection and control applications. PMUs rely on precise time synchronization, the ...
2019Easily Deployable Underwater Acoustic Navigation System for Multi-Vehicle Environmental Sampling Applications
Alcherio Martinoli, Alexander Bahr, Felix Stephan Schill, Anwar Ahmad Quraishi
Water as a medium poses a number of challenges for robots, limiting the progress of research in underwater robotics vis-a-vis ground or aerial robotics. The primary challenges are satellite based positioning and radio communication being unusable due to hi ...
IEEE2019Impact of Time Dissemination Technologies on Synchrophasor Estimation Accuracy
Mario Paolone, Asja Derviskadic, Guglielmo Frigo
The paper discusses the influence of the time synchronization technique on the synchrophasor estimation accuracy in modern Phasor Measurement Units (PMU). Specifically, we make reference to Global Positioning System (GPS), Precision Time Protocol (PTP) and ...
