Differential Fault Attack on TWINE Block Cipher with Nibble
Haoxiang Luo, Yifan Wu, Weijian Chen · 2020
TWINE cipher is a generalized Feistel structure algorithm, which can be applied to Internet of things terminals with limited computing resources because of its good performance. Since it was proposed, it has been widely studied by academia and industry. This paper analyses the permutation law of TWINE cipher, and proposes a differential fault attack method with its differential property. By selecting 33th,34thand 35throunds for the nibble differential fault attack, the original 80-bit key can be recovered from 24 nibble fault ciphertext, with the computational complexity and data complexity of 210.47and 210.58, respectively. The results show this method has great advantages over other public literatures about the cryptanalysis of TWINE cipher.
