Location-Dependent EM Leakage of the ATxmega Microcontroller

Nowadays, low power microcontrollers are widely deployed in wireless sensor networks, also implementing cryptographic algorithms. These implementations are potential targets of so-called side-channel analysis (SCA) attacks which aim to reveal secret information, e.g. a secret key. In this work we evaluate the resistance of AES implementations on an Atmel AVR XMEGA microcontroller against SCA at...
