Differential Fault Analysis on SMS4 using a single fault
2011
Information Processing Letters
Differential Fault Analysis (DFA) attack is a powerful cryptanalytic technique that could be used to retrieve the secret key by exploiting computational errors in the encryption (decryption) procedure. In the present paper, we propose a new DFA attack on SMS4 using a single fault. We show that if a random byte fault is induced into either the second, third, or fourth word register at the input of the 28-th round, the 128-bit master key could be recovered with an exhaustive search of 22.11 bits
