Cryptographic algorithms are undeniable components in providing communication security. On the other hand, to ensure the security of an algorithm, its security against various attacks must be evaluated. In addition to evaluating the security of cryptographic primetives against statistical attacks such as linear cryptanaylsis, differential cryptanalysis and etc., security of cryptosystems against side-channel attack is always a concern. Among side-channel attacks, fault injection-based attacks received extensive attention. Among fault injection attacks, differential fault analysis is considered in this paper. Although differential fault analysis has been applied to many block ciphers, the security of a class of block ciphers known as ARX ciphers has received less attention. In this direction, in this paper, we analyze the security of an ARX block cipher known as MARX-2 against differential fault attack. As a result of this attack, we recover the n-bit key of the cipher using n-bit fault injection. The applied attack is the first differential fault analysis of MARX-2 block cipher, to the best of our knowledge.
