  4. Abstract:
  5. A specific class of differential cryptanalytic approach, known as Related Key Boomerang Attack, has been successfully applied to several symmetric cryptographic primitives in particular encryption schemes such as Advanced Encryption Standard (AES). In this paper, we propose a new related-key boomerang attack on 8-round AES-256, a couple of ones on 9-round following the work of Gorski et al. In the first one, we attacked 8-round AES-256 with the time complexity of 279 and the data complexity of 259. The extended 8-round attack on 9-round AES-256 is more efficient than previous attacks from both time and data complexity perspectives
