Abstract: This paper shows the boomerang attack on 7 round reduced AES-192.The attack needs 239 chosen plaintexts,2183 adaptively chosen ciphertexts,and the time complexity of this attack is 2183 steps mainly encrypting the texts,237 bytes of memory is needed.This kind of attack can also be applied to other SPN ciphers with incomplete diffusion.

Key words: AES, boomerang, differential

摘要: 给出了7轮AES-192的飞去来器攻击。攻击需要239选择明文,2183自适应选择密文,时间复杂度为2183次加密操作,需要237字节的存储空间。这种攻击也可以用于其它SPN结构的没有足够混合的算法。
