Differential electromagnetic analysis implies measuring electromagnetic radiations of a cipher-circuit in an attempt to uncover part of a cipher key. Cryptographic security gets compromised if the electromagnetic emissions correlate with those from a hypothetical model of the cipher circuit. This article describes experimental setup for performing electromagnetic analysis as well as the measurement probe that is the critical piece of equipment for performing electromagnetic attacks. Most of the probes that are used for electromagnetic attacks in the published papers are self-made and no detailed specification is available for them. The accuracy and efficiency of the designed setup was verified by practical results obtained from real implementation of both attacks on an AT89C51AC2 microcontroller. The results of this work can be served for protecting microprocessor-based security tokens such as smart cards that are vulnerable to these kinds of attacks. |
