Abstract :
SMS4 is a 128-bit block cipher published by as released as the symmetric-key encryption standard of Wireless Local Area Network(WLAN) by China in 2006. On the differential analysis principle, we propose an extension of differential fault attack on the SMS4 cipher. Mathematical analysis shows that our attack can recover its secret key by introducing about 40 faulty ciphertexts. Our work expands the locations of the fault injection into SMS4.
