Improved cube attack on stream ciphers
Ding Lire · Computer Engineering and Applications Journal · 2015
Recently, Cube attack has achieved lots of attention. In this paper the improved Cube attack is proposed against the stream ciphers. The improved attack combines Cube attack with algebraic attack with the latter one being the base of the former one, which renders the decrease of the complexity. Based on the former research, the combination forms of annihilators and Cube attack are extended. Meanwhile, the improved attack is applied to Lili-128 algorithm and 88 key bits are recovered within the data complexity of 210 through some 3 dimensional cubes.
