| Abstract: | The block cipher Threefish is the main component of Skein, which is based on ARX. Based on the efficient algorithms for calculating the differential of modular addition, we extend local collisions of Threefish-256 to more round by using related-key differential of addition in this paper. A related-key boomerang distinguish attack is proposed on 31-round Threefish-256 with a time complexity of 2234. |
