Coordinated Electromagnetic Side-Channel Attacks for Voter--Ballot Linking: A Case Study of the Brazilian E-Polling System
Leandro Hyeda, Kleber V. Cardoso, Antonio Oliveira-Jr +1
In this work, we show how two adversaries (Eve and Mallory) can coordinate an electromagnetic side-channel attack to recon- struct the vote displayed on an e-voting machine (EVM) a…
Fast Frame Rate Estimation in Electromagnetic Side-Channel Attacks on Public Systems
Alyson Isaluski, Leonardo Teodoro, Kleber V. Cardoso +2
Frame refresh rate estimation is a fundamental step in identifying compromising harmonic frequencies in electromagnetic side-channel attacks. Methods based on discrete linear autoc…
Do Electromagnetic Side-Channel Attacks Threaten Electronic Polling Stations? Scenarios and Recommendations
Lucas Brito, Leonardo Teodoro, Pedro Tomaz +4
This paper investigates the threat to ballot secrecy in the Brazilian electronic voting machine (UEB) posed by electromagnetic side-channel attacks, also known as TEMPEST attacks.…
Computation-Limited Signals in Practice: A Throughput Anomaly in Software-Defined O-RAN PHY Layers
Gabriel Alessi Posonski, Saulo Queiroz, João P. Vilela +3
We formalize a performance anomaly in software-based wireless physical-layer (PHY) implementations, a key enabling technology for Open Radio Access Network (O-RAN) systems. For a f…
Pre-Characterization of Electromagnetic Side-Channel Leakage Using Publicly Available Information: A Case Study on E-Voting Interfaces
Leonardo Teodoro, Kemuel L. Vieira, Saulo Queiroz
In this work, we study the interface of the Brazilian e-Voting Machine (BVM) in the context of electromagnetic side-channel threats commonly referred to as TEMPEST attacks. In a TE…
