Abstract
In this paper we show that the full-round Eagle-64 and Eagle-128 are vulnerable to the related-key amplified boomerang attack. The attack on the full-round Eagle-64 requires 265 full-round Eagle-64 decryptions with 237 related-key chosen ciphertexts, while the attack on the full-round Eagle-128 requires about 2154.51 full-round Eagle-128 encryptions with 294.83 related-key chosen plaintexts. These works are the first known attacks on Eagle-64 and Eagle-128.
