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 in the file

Please consult the file readme.txt inside the tarball for details.

The dataset with power-supply current traces is available in the 1.75 GB file

You need to uncompress this gzip file, e.g. with gunzip.

If you find the code or data useful please cite the above paper in your work.

Data from different devices

The target device "Beta" used above is one of our four test boards. Recordings from all four devices are available below.

Alpha e2_bat_fb_alpha_raw_s_0_3071.raw.gz
Beta e2_bat_fb_beta_raw_s_0_3071.raw.gz
Gamma e2_bat_fb_gamma_raw_s_0_3071.raw.gz
Delta e2_bat_fb_delta_raw_s_0_3071.raw.gz

These datasets from four different devices are the basis for the evaluation of template attacks on different devices described in the paper

A package of MATLAB scripts to reproduce some of the results shown in that paper is under preparation.
