Abstract :
SMS4 is a 128-bit block cipher published as the symmetric-key encryption standard of Wireless Local Area Network(WLAN) by China in 2006. By inducing faults into the key schedule, we propose an improved method of differential fault attack on the key schedule of the SMS4 cipher. The result shows that our attack can recover its secret key by introducing 4 faulty ciphertexts.
