Leveraging EM Side-Channel Information to Detect Rowhammer Attacks

Explore a novel approach to detecting rowhammer attacks using electromagnetic (EM) side-channel information in this IEEE conference talk. Learn about RADAR (Rowhammer Attack Detection via A Radio), which leverages recognizable hammering-correlated sideband patterns in the DRAM clock signal spectrum to expose potential attacks, even those hidden in encrypted and isolated environments like Intel SGX enclaves. Discover how the researchers overcome challenges posed by spread-spectrum clocking (SSC) through a proposed de-spreading method. Examine the effectiveness and robustness of this classification-based defense technique, evaluated on a RADAR prototype under various scenarios. Gain insights into this groundbreaking investigation that utilizes EM side-channel information for rowhammer defense, offering a unique perspective on hardware security without imposing performance overhead on protected systems.
