Randomized Caches in HW: Overheads And Limitations (RUB, Max Planck, Georgia Tech)

Researchers at Ruhr University Bochum, the Max Planck Institute for Security and Privacy, and Georgia Tech published “Randomized Caches in Hardware: Challenges and Trade-offs.” Abstract Excerpt: “Randomized caches protect against side-channel attacks by obfuscating the mapping of memory addresses to cache locations. Existing proposals typically describe architectural behavior, leaving practical hardware implementation challenges largely unexplored.... » read more
