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

Research details an improved method for estimating frame refresh rates in electromagnetic side-channel attacks, a critical step for identifying compromising harmonic frequencies. The proposed technique reduces computational complexity from O(N log N) to O(N) by leveraging prior knowledge of display resolution, without compromising accuracy, as demonstrated through experiments with software-defined radios.

This development significantly enhances the efficiency of electromagnetic side-channel attacks, making such analyses faster and potentially more accessible. For systems relying on display outputs, including public infrastructure like electronic voting machines, this advancement means a heightened risk of identifying sensitive information through previously computationally intensive attack vectors.

Frame refresh rate estimation is a fundamental step in identifying compromising harmonic frequencies during electromagnetic side-channel attacks.
