ePrint Report: Allocating Rotational Cryptanalysis based Preimage Attack on 4-round Keccak-224 for Quantum Setting

Runsong Wang, Xuelian Li, Juntao Gao, Hui Li, Baocang Wang

In this paper, we aim to present a quantum setting oriented preimage attack against 4-round Keccak-224. An important technique we called the allocating rotational cryptanalysis takes the preimage attack into the situation of 2-block preimage recovery. With the conditions on the middle state proposed by Li et al., we use the generic quantum preimage attack to …
