Impossible Differential Cryptanalysis of FOX
Zhongming Wu, Xuejia Lai, Bo Zhu, and Yiyuan Luo
Abstract
Block ciphers are the very foundation of computer and information
security. FOX, also known as IDEA NXT, is a family of block ciphers
published in 2004 and is famous for its provable security to
cryptanalysis. In this paper, we apply impossible differential
cryptanalysis on FOX cipher. We find a 4-round impossible
difference, by using which adversaries can attack 5, 6 and 7-round
