| English Abstract: | Grøstl[1] is one of the second round candidates of the SHA-3 competition[2] hosted by NIST, which aims to find a new hash standard. In this paper, we studied equivalent expressions of the generalized AES-like permutation. We found that four rounds of the AES-like permutation can be regarded as a Hyper-Sbox. Then we further analyzed the differential properties of both Super-Sbox and Hyper-Sbox. Based on these observations, we give an 8-round truncated differential path of the generalized AES-like permutation, which can be used to construct a distinguisher of 8-round Grøstl-256 permutation with 264 time and 264 memory. This is the best known distinguisher of reduced-round Grøstl permutation. © 2011 Springer-Verlag. |
