The Boomerang Attack on 5 and 6-round Reduced AES
Alex Biryukov · Lirias · 2005
Abstract. In this note we study security of 128-bit key 10-round AES against the boomerang attack. We show attacks on AES reduced to 5 and 6 rounds, much faster than the exhaustive key search and twice faster than the “Square ” attack of the AES designers. The attacks are structural and apply to other SPN ciphers with incomplete diffusion. 1
