Lord of the Ring(s): Side Channel Attacks on the
CPU On-Chip Ring Interconnect Are Practical
https://arxiv.org/abs/2103.03443
"To address the first challenge, we perform a thorough reverse engineering of Intel’s “sophisticated ring protocol” [60,90] that handles communication on the ring intercon-
nect."
....
"Finally, AMD CPUs utilize other proprietary technologies known as Infinity Fabric/Architecture for their on-chip interconnect [20, 96]. Investigating the feasibility of our attack on these platforms requires future work. However, the techniques we use to build
our contention model can be applied on these platforms too."
