Résumé : In 2015, Kalyna has been chosen as the new Ukrainian standard block cipher. Kalyna is an AES-like block cipher with a noninvertible key schedule. In this paper we perform the first side-channel analysis of Kalyna by performing a CPA attack on the round keys of Kalyna 128/128. Our work is based on simulations and real experiments performed on a software implementation on a micro-controller. Our attack extracts the round keys with probability 0.96 using 250 measurements.
