Query: CacheFX: A Framework for Evaluating Cache Security   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 components for leaking information, have been devised, mostly
targeting shared caching components. In response, the research community has
proposed multiple cache designs that aim at curbing the source of side
channels. With multiple competing designs, there is a need for assessing the
level of security against side-channel attacks that each design offers.
  In this work we propose CacheFX, a flexible framework for assessing and
evaluating the resilience of cache designs to side-channel attacks. CacheFX
allows the evaluator to implement various cache designs, victims, and
attackers, as well as to exercise them for assessing the leakage of information
via the cache.
  To demonstrate the power of CacheFX, we implement multiple cache designs and
replacement algorithms, and devise three evaluation metrics that measure
different aspects of the caches:(1) the entropy induced by a memory access; (2)
the complexity of building an eviction set; and (3) protection against
cryptographic attacks. Our experiments highlight that different security
metrics give different insights to designs, making a comprehensive analysis
mandatory. For instance, while eviction-set building was fastest for randomized
skewed caches, these caches featured lower eviction entropy and higher
practical attack complexity. Our experiments show that all non-partitioned
designs allow for effective cryptographic attacks. However, in state-of-the-art
secure caches, eviction-based attacks are more difficult to mount than
occupancy-based attacks, highlighting the need to consider the latter in cache
design.
