"It's a Trap!"-How Speculation Invariance Can Be Abused with Forward Speculative Interference
Pavlos Aimoniotis, Christos Sakalis, Magnus Själander +1
Speculative side-channel attacks access sensitive data and use transmitters to leak the data during wrong-path execution. Various defenses have been proposed to prevent such inform…
Selectively Delaying Instructions to Prevent Microarchitectural Replay Attacks
Christos Sakalis, Stefanos Kaxiras, Magnus Själander
MicroScope, and microarchitectural replay attacks in general, take advantage of the characteristics of speculative execution to trap the execution of the victim application in an i…
On Value Recomputation to Accelerate Invisible Speculation
Christos Sakalis, Zamshed I. Chowdhury, Shayne Wadle +5
Recent architectural approaches that address speculative side-channel attacks aim to prevent software from exposing the microarchitectural state changes of transient execution. The…
