Title:
Quantum Cryptanalysis of 5 rounds Feistel schemes and Benes schemes
Authors: Maya Chartouny, Jacques Patarin, Ambre Toulemonde
Abstract:In this paper, we provide new quantum cryptanalysis results on 5 rounds (balanced) Feistel schemes and on Benes schemes. More precisely, we give an attack on 5 rounds Feistel schemes in \Theta(2^{2n/3}) quantum complexity and an attack on Benes schemes in \Theta(2^{2n/3}) quantum complexity, where n is the number of bits of the internel random functions.
