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.

Key words: Rijndael, meet-in-the-middle cryptanalysis, AES, key expansion algorithm
