Electromagnetic Analysis: Concrete Results

Abstract

Although the possibility of attacking smart-cards by analyzing their electromagnetic power radiation repeatedly appears in research papers, all accessible references evade the essence of reporting conclusive experiments where actual cryptographic algorithms such as des or rsa were successfully attacked.

This work describes electromagnetic experiments conducted on three different cmos chips, featuring different hardware protections and executing a des, an alleged COMP128 and an RSA. In all cases the complete key material was successfully retrieved.
