Dinur and Shamir’s cube attack has attracted significant attention in the literature. Nevertheless, the lack of implementations achieving effective results casts doubts on its practical relevance. On the theoretical side, promising results have been recently achieved leveraging on division trails. The present paper follows a more practical approach and aims at giving new impetus to this line of research by means of a cipher-independent flexible framework that is able to carry out the cube attack on GPU/CPU clusters. We address all issues posed by a GPU implementation, providing evidence in support of parallel variants of the attack and identifying viable directions for solving open problems in the future. We report the results of running our GPU-based cube attack against round-reduced versions of three well-known ciphers: Trivium, Grain-128 and SNOW 3G. Our attack against Trivium improves the state of the …
