A method to detect counterfeit integrated circuits through the use of a microwave resonator
TS-048646 — A novel method to detect a counterfeit integrated circuit (IC) and to authenticate an IC using the electromagnetic characteristics of the IC and a resonator
The presence of counterfeit integrated circuits (commonly referred to as “ICs” or “chips”) in a supply chain, such as a military supply chain, can result in either a failure of a critical system or a compromise of the data on that system. These counterfeit chips may not be …
