Breaking Blockchain Rationality with Out-of-Band Collusion
Bryan Alexander Ford, Verónica del Carmen Estrada Galiñanes, Louis-Henri Manuel Jakob Merino, Haoqian Zhang, Mahsa Bastankhah
Blockchain systems often rely on rationality assumptions for their security, expecting that nodes are motivated to maximize their profits. These systems thus design their protocols to incentivize nodes to execute the honest protocol but fail to consider ou ...
Cham2024Evading Voltage-Based Intrusion Detection on Automotive CAN
Mathias Josef Payer, Duo Xu, Rohit Bhatia
The controller area network (CAN) is widely adopted in modern automobiles to enable communications among in-vehicle electronic control units (ECUs). Lacking mainstream network security capabilities due to resource constraints, the CAN is susceptible to the ...
INTERNET SOC2021Time-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 ...
EPFL2021Que Sera Consensus: Simple Asynchronous Agreement with Private Coins and Threshold Logical Clocks
Bryan Alexander Ford, Philipp Svetolik Jovanovic
It is commonly held that asynchronous consensus is much more complex, difficult, and costly than partially-synchronous algorithms, especially without using common coins. This paper challenges that conventional wisdom with que sera consensus QSC, an approac ...
2020Breaking the FF3 Format Preserving Encryption
Serge Vaudenay, Fatma Betül Durak
The NIST standard FF3 scheme (also known as BPS scheme) is a tweakable block cipher based on a 8-round Feistel Network. We break it with a practical attack. Our attack exploits the bad domain separation in FF3 design. The attack works with chosen plaintext ...
2017iPRP: Parallel Redundancy Protocol for IP Networks
Jean-Yves Le Boudec, Dan-Cristian Tomozei, Miroslav Popovic
Reliable packet delivery within stringent time limits is a key requirement of smart-grid and other industrial communication networks. The Parallel Redundancy Protocol (PRP), used in this context, duplicates packets at the MAC layer over parallel networks a ...
