Abstract

This paper proposes two Differential Fault Attacks on the lightweight block cipher KLEIN. Variant one targets the intermediate state of the cipher. Using at least five faulty ciphertexts, the attacker is able to determine the last round key. The second variant, which works only on KLEIN-64, injects a byte-fault in the key schedule and requires at least four faulty ciphertexts in order to determine the whole key. Furthermore, we demonstrate the efficiency of both attack methods by simulation.

There are two additional publications in chinese: A DFA by Wang et al. [13] and a DFA by Cunyan et al. [4]. However, the latter obviously uses the generic approach of injecting single-bit faults before the last S-Box operation to exploit the differential distribution table (cf. the appendix of the original KLEIN publication [6]) and discard key hypotheses which lead to impossible differentials.

i.e. for the attack on the key schedule, \(complexity = 2^{\prod _{i=0}^{7} |ARK^{R}_{i}|}\).
