In this paper we present the first differential fault analysis (DFA) of SHA-3. This attack can recover the internal state of two versions of SHA-3 (namely, SHA3-512 and SHA3-384) and can be used to forge MAC’s which are using these versions of SHA-3. Assuming that the attacker can inject a random single bit fault on the intermediate state of the hash computation, and given the output of the SHA-3 version for a correct message and 80 faulty messages, we can extract 1592 out of the 1600 bits of the compression function’s internal state. To the best of our knowledge, this is the first public analysis of SHA-3 against DFA. Although our results do not compromise any security claim of SHA-3, it shows the feasibility of DFA on this scheme and possibly other Sponge based MACs and increases our understanding of SHA-3. © Springer International Publishing Switzerland 2015.
