Abstract

256-bit block cipher XSB(eXtended Spn Block cipher) was proposed in 2012 and has a symmetric structure in encryption and decryption process. In this paper, we propose a differential fault analysis on XSB. Based on a random byte fault model, our attack can recover the secret key of XSB by using only two random byte fault injection. This result is the first known cryptanalytic result on the target algorithm.
