Title:
New Impossible Differential Characteristic of SPECK64 using MILP

Authors: HoChang Lee, HyungChul Kang, Deukjo Hong, Jaechul Sung, Seokhie Hong

Abstract:

Impossible differential attack is one of powerful methods for analyzing block ciphers. When designing block ciphers, it must be safe for impossible differential attacks. In case of impossible differential attack, the attack starts from finding the impossible differential characteristic. However, in the case of the ARX-based block cipher, these analyzes were difficult due to the addition of modulus. In this paper, we introduce 157 new six-round impossible differential characteristics of ARX-basef block cipher, SPECK64, using Mixed Integer Linear Programming (MILP) base impossible differential characteristic search proposed by Cui [3] etc.
