In this paper the authors describe several ideas related to Differential Fault Attack (DFA) on MICKEY 2.0, a stream cipher from eStream hardware profile. Using the standard assumptions for fault attacks, they first show that if the adversary can induce random single bit faults in the internal state of the cipher, then by injecting around 216:7 faults and performing 232:5 computations on an average, it is possible to recover the entire internal state of MICKEY at the beginning of the key-stream generation phase.
