Cube Testers on Bivium
Li Shun-Bo, Yan Wang, Jialong Peng · 2010
Bivium is a reduced version of the stream cipher Trivium, using 177 stages and only 2 feedback registers. In this paper, we present a cube tester which combines the cube attack with efficient algebraic property-testers. By this method, Bivium was broken with complexity about 226simulations.
