Differential analysis of the ZUC-256 initialisation
Steve Babbage and Alexander Maximov
Abstract
This short report contains results of a brief cryptanalysis of the initialisation phase of ZUC-256. We find IV differentials that persist for 26 of the 33 initialisation rounds, and Key differentials that persist for 28 of the 33 rounds.
