Nowhere to Hide: Monitoring Side Channels for Supply Chain Resiliency
Domenic J. Forte, Ben Amaba, Cate Richards, Jeff Daniels · IEEE reliability magazine · 2024
Side channels are nonfunctional characteristics of a program or hardware (HW), such as power consumption, electromagnetic radiation (EM), temperature, timing, or memory consumption, that allow one to infer information about the program, software (SW), or HW. Often, attackers take advantage of these side channels to uncover secrets from cryptographic systems, web applications, and more. However, in the right hands, side-channel analysis can also be used for anomaly detection where it has several advantages over traditional solutions.
