Differential power analysis (DPA) has been a threat vector on the chip landscape for a number of years. It was discovered around the mid 1990s by the teams at Rambus’ Cryptography Research Division, and turned out to be a very effective tool for compromising the ubiquitous SIM card environment.

“The most traditional market for DPA has been with smart cards because of their limitations – consumer goods type of devices, low cost, limited power,” says Simon Blake-Wilson, vice president of products and marketing at Rambus. “That makes them a fertile landscape for DPA. Of course, DPA is capable of side channel attacks on just about any chip, but the relative lack of control over, and ease with which one could obtain SIM cards made them easy pickings for such power analysis techniques.
