Grizzly: power-analysis traces for an 8-bit load instruction

The “Grizzly” dataset consists recordings of the power-supply current of the 8-bit CPU Atmel XMEGA 256 A3U, an easily available microcontroller without side-channel countermeasures. It was prepared by Omar Choudary in August 2013 and forms the basis for the comparison of different template attacks described in the paper

The MATLAB scripts for implementing the attacks described in the paper are available here. Please consult the file readme.txt inside the tarball for details.

The dataset with power-supply current is available here. You need to uncompress this file, e.g. by using gunzip.
