Attack Directories, Not Caches - Side Channel Attacks in a Non Inclusive World

Explore a groundbreaking conference talk that delves into novel side channel attacks on non-inclusive cache hierarchies. Learn how researchers reverse engineered the directory structure in sliced, non-inclusive cache hierarchies to develop the first cross-core Prime+Probe attack and high-bandwidth Evict+Reload attack on modern systems. Discover the implications for cloud security as the talk demonstrates how these attacks can extract key bits during RSA operations in GnuPG on state-of-the-art Intel Skylake-X servers. Gain insights into the evolving landscape of cache attacks and their continued relevance despite changes in cache hierarchy design.
