摘要:
The boomerang attack is one of the many extensions of the original differential attack. It has been widely applied to successfully attack many existing ciphers. In this paper, we investigate an extended version of the boomerang attack and show that it is still a very powerful tool especially in the related-key setting. A new branch-and-bound searching strategy which involves the extended boomerang framework is then introduced. We provide an improved cryptanalysis on the KATAN family (a family of hardware-oriented block ciphers proposed in CHES 2009) based on the boomerang attack. In the relate...
