Improved Cryptanalysis of GIFT-64

In this paper, we propose new differential attacks against the block cipher GIFT-64. First we demonstrate how the parallel matching algorithm proposed by Naya-Plasencia at CRYPTO’11 as an advanced list-merging algorithm can be leveraged to enhance differential attacks, overcoming a previously assum...
