Modern cryptography requires the ability to securely generate pseudorandom numbers. However, despite decades of work on side channel attacks, there is little discussion of their application to pseudor...
Fooling the Sense of Cross-core Last-level Cache Eviction based Attacker by Prefetching Common Sense
implementation information hiding
2019/4/22
Cross-core last-level cache (LLC) eviction based sidechannel
attacks are becoming practical because of the inclusive
nature of shared resources (e.g., an inclusive LLC), that creates
back-invalidat...
