Differential Fault Analysis of MICKEY-128 2.0

This paper presents a differential fault analysis of the MICKEY-128 2.0 stream cipher, one of the finalist of eStream project. The current attack works on MICKEY-128 2.0 with 320 state register-bits and requires 480 number of random single bit faults to break it. Till date, only two fault attacks against MICKEY family are available in literature, one attack on MICKEY-128 and another on MICKEY 2.0. The attack on MICKEY-128 with same 320 register bits required 640 number of faults whereas the other attack on MICKEY 2.0 with 200 state register bits required $2^{16.7} number of faults. To the best of our knowledge the current attack gives the best performance with respect to the number of faults to be induced against the highest version of MICKEY, MICKEY-128 2.0.
