SNOW 2.0 was developed by Johansson and Ekdahl in 2002, as a modified version of SNOW 1.0. In this paper we present the application of linear (masking) attack to SNOW 2.0 stream cipher. Our attack requires 2 225 output words (2 230 bits) and 2 225 steps of analysis to distinguish the output of SNOW 2.0 from a truly random bit sequence.doi:10.1007/978-3-540-24654-1_16 fatcat:nhchu6rks5cffmn7l5rztqmtwq
