Improved guess-and-determine and distinguishing attacks on SNOW-V

Improved guess-and-determine and distinguishing attacks on SNOW-V

In this paper, we investigate the security of SNOW-V, demonstrating two guess-and-determine (GnD) attacks against the full version with complexities 2384 and 2378, respectively, and one distinguishing attack against a reduced variant with complexity 2303. Our GnD attacks use enumeration with recursi...
