Cryptanalysis of 2-round KECCAK-384
Rajendra Kumar and Nikhil Mittal and Shashank Singh
Abstract
In this paper, we present a cryptanalysis of round reduced Keccak-384 for 2 rounds. The best known preimage attack for this variant of Keccak has the time complexity $2^{129}$. In our analysis, we find a preimage in the time complexity of $2^{89}$ and almost same memory is required.
