Electromagnetic Side Channels of an FPGA Implementation of AES.
Vincent Carlier, Hervé Chabanne, Emmanuelle Dottax, Hervé Pelletier · 2004
We show how to attack an FPGA implementation of AES where all bytes are processed in parallel using differential electromagnetic analysis. We first focus on exploiting local side channels to isolate the behaviour of our targeted byte. Then, generalizing the Square attack, we describe a new way of retrieving information, mixing algebraic properties and physical observations.
