Modern * 86 processors feature many prefetch instructions that developers can use to
enhance performance. However, with some prefetch instructions, users can more directly …

The aggressive performance optimizations in modern microprocessors can result in security
vulnerabilities. For example, timing-based attacks in processor caches can steal secret keys …

This paper studies the mitigation of memory timing side channels, where attackers utilize
contention within DRAM controllers to infer a victim's secrets. Already practical, this class of …

Over the last two decades, the danger of sharing resources between programs has been
repeatedly highlighted. Multiple side-channel attacks, which seek to exploit shared …

Caches are key microarchitectural components of modern processors to improve memory
access speed. However, attackers can readily implement timing side-channel attacks by …

The sharing of last-level cache (LLC) among different CPU cores makes cache vulnerable to
side channel attacks. An attacker can get private information about co-running applications …

Timing-based side and covert channels in processor caches continue to be a threat to
modern computers. This work shows for the first time, a systematic, large-scale analysis of …

Conflict-based cache attacks can leak critical information from target programs. Accordingly,
randomization-based cache designs have emerged as an efficient and LLC-favorable way …

Caches are vulnerable to side-channel attacks as a type of shared hardware resource. Most
existing defense methods can be categorized into two categories: partition and …

Recent work has demonstrated the security risk associated with micro-architecture side-
channels. The cache timing side-channel is a particularly popular target due to its availability …
