Do Electromagnetic Side-Channel Attacks Threaten Electronic Polling Stations? Scenarios and Recommendations

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. In these attacks, screen content can be reconstructed remotely by intercepting electromagnetic emanations associated wi...

Fast Frame Rate Estimation in Electromagnetic Side-Channel Attacks on Public Systems

Frame refresh rate estimation is a fundamental step in identifying compromising harmonic frequencies in electromagnetic side-channel attacks. Methods based on discrete linear autocorrelation DLA are robust across different scenarios and require a computational complexity of $ON\log N$ for a signa...
