WebMay 23, 2024 · Transient execution attacks use microarchitectural covert channels to leak secrets that should not have been accessible during logical program execution. Commonly used micro-architectural covert channels are those that leave lasting footprints in the micro-architectural state, for example, a cache state change, from which the secret is recovered … WebIn a related development, Behnia et al. demonstrate that Speculative Interference [5] can break (under some assumptions) the DoM and InvisiSpec defenses. Up until now, the transmitter instructions were considered to be exclusively under speculative execution. With the introduction of Speculative Interference attacks, this has changed.
