PerSpectron: Detecting Invariant Footprints of Microarchitectural Attacks with Perceptron

Detecting microarchitectural attacks is critical given their proliferation in recent years. Many of these attacks exhibit intrinsic behaviors essential to the nature of their operation, such as creating contention or misspeculation. This study systematically investigates the microarchitectural...
