Security evaluation of lightweight block ciphers plays a critical role to determine security margin of these ciphers. One of the methods to find the security margin of block ciphers is biclique cryptanalysis. In this paper, we present a new schematic for biclique attack which combines asymmetric biclique and early abort technique. Then, we apply it against Twine-128 to evaluate the security margin of Twine-128. As a result, we present two cryptanalysis for Twine-128, one with 𝟐𝟏𝟐𝟓.𝟕𝟓 computational complexity and 𝟐𝟔𝟎 data complexity, and the other with 𝟐𝟏𝟐𝟔.𝟏𝟔 computational complexity and 𝟐𝟖 data complexity. To the best of our knowledge, our results are the best in computational and data complexity point of view for full round of Twine-128.
