Abstract

Microarchitectural timing channels expose hidden hardware states though timing.We survey recent attacks that exploit microarchitectural features in shared hardware, especially as they are relevant for cloud computing.We classify types of attacks according to a taxonomy of the shared resources leveraged for such attacks. Moreover, we take a detailed look at attacks used against shared caches. We survey existing countermeasures. We finally discuss trends in attacks, challenges to combating them, and future directions, especially with respect to hardware support.
