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.en© Springer-Verlag Berlin Heidelberg 2016Microarchitectural timing attacks; cache-based timing attacks; countermeasures; trend in the attacksJournal article003006897410.1007/s13389-016-0141-62-s2.0-85038210205350472Yarom, Y.
