Cryptanalysis of 1-Round KECCAK
Rajendra Kumar and Mahesh Sreekumar Rajasree and Hoda AlKhzaimi
Abstract
In this paper, we give the first pre-image attack against 1- round KECCAK-512 hash function, which works for all variants of 1- round KECCAK. The attack gives a preimage of length less than 1024 bits by solving a system of 384 linear equations. We also give a collision attack against 1-round KECCAK using similar analysis.
Note: In the previous submission we gave preimage attack with 5 message blocks. With similar analysis we brought it down to 2 message block.
