Feasibility 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 ...

Undetectable Timing-Attack on Linear State-Estimation by Using Rank-1 Approximation

Jean-Yves Le Boudec, Mario Paolone, Marco Pignati, Sergio Barreto Andrade, Gyorgy Miklos Dan

Smart-grid applications based on synchrophasor measurements have recently been shown to be vulnerable to timing attacks. A fundamental question is whether timing attacks could remain undetected by bad-data detection algorithms used in conjunction with stat ...

Cyber-attack on Packet-Based Time Synchronization Protocols: the Undetectable Delay Box

Jean-Yves Le Boudec, Sergio Barreto Andrade, Aswin Suresh

We present a cyber-attack on packet-based time synchronization protocols (PBTSP) with high-accuracy requirements. The cyber-attack is undetectable from the PBTSP's perspective and exploits a vulnerability that is in the nature of all PBTSPs. It can be succ ...

Real-Time State Estimation of the EPFL-Campus Medium-Voltage Grid by Using PMUs

Sidi-Rachid Cherkaoui, Jean-Yves Le Boudec, Mario Paolone, Teklemariam Tsegay Tesfay, Dan-Cristian Tomozei, Styliani Sarri, Paolo Romano, Miroslav Popovic, Marco Pignati, Lorenzo Zanni, Sergio Barreto Andrade, Maaz Mashood Mohiuddin, German Dario Flores Ponce

We describe the real-time monitoring infrastructure of the smart-grid pilot on the EPFL campus. We experimentally validate the concept of a real-time state-estimation for a 20 kV active distribution network. We designed and put into operation the whole inf ...

Security Vulnerabilities of the Cisco IOS Implementation of the MPLS Transport Profile

Jean-Yves Le Boudec, Teklemariam Tsegay Tesfay, Miroslav Popovic, Sergio Barreto Andrade, Udaya Upul Kumara Jayasinghe

We are interested in the security of the MPLS Transport Profile (MPLS-TP), in the context of smart-grid communication networks. The security guidelines of the MPLS-TP standards are written in a complex and indirect way, which led us to pose as hypothesis t ...
