Fault-based Attacks on the Bel-T Block Cipher Family

Philipp Jovanovica and Ilia Polianb

University of Passau, Germany.


We present the first fault-based attack on the Bel-T block cipher family which has been adopted recently as a national standard of the Republic of Belarus. Our attack successfully recovers the secret key of the 128-bit, 192-bit and 256-bit versions of Bel-T using 4, 7 and 10 fault injections, respectively. We also show the results from our comprehensive simulation-based experiments.

Keywords: Fault-based cryptanalysis, Fault injection, Block cipher.
