| 摘 要： | 给出了AES-128相邻两轮的轮密钥之间的一个线性关系。通过将这一关系与Hüseyin Demirci和Ali Aydın Selçuk在2008年提出的一个5轮AES区分器相结合,构造了一个8轮AES区分器。在这个8轮AES区分器的基础上,设计了一个对10轮AES-128的中间相遇攻击方案。这一方案在预计算阶段可以节省相当大的存储空间。

| Abstract: | Some relationship between different adjacent round keys of AES-128 was discovered. Combining this relationship with the principle of the 5-round distinguisher presented by Hüseyin Demirci and Ali Aydın Selçuk in 2008, an 8-round distinguisher was proposed. Based on this distinguisher, a meet-in-the-middle attack on 10-round AES-128 was designed. And, this distinguisher can save a considerable memory space in the precomputation step. |
