Delay-on-Squash: Stopping Microarchitectural Replay Attacks in Their Tracks

Autor: Christos Sakalis, Stefanos Kaxiras, Magnus Själander

Publikováno v: ACM Transactions on Architecture and Code Optimization. 20:1-24

MicroScope and other similar microarchitectural replay attacks take advantage of the characteristics of speculative execution to trap the execution of the victim application in a loop, enabling the attacker to amplify a side-channel attack by executi
