Explore a cryptographic attack technique presented at Eurocrypt 2020 in this 26-minute conference talk. Delve into the Retracing Boomerang Attack, a novel approach to cryptanalysis developed by Orr Dunkelman, Nathan Keller, Eyal Ronen, and Adi Shamir. Learn about block ciphers, differential attacks, and the boomerang attack before diving into the specifics of the retracing boomerang method. Discover variants such as the shifting and mixing retracing attacks, and examine their applications to AES, including the yo-yo distinguisher for 4-round AES and attacks on 5-round AES. Gain insights into cutting-edge cryptanalysis techniques and their potential impact on cipher security.
