| Sumario: | In this paper, we present a review of the work [1]. In this work a complete setup to break ASIC implementations of standard Trivium stream cipher was presented. The setup allows to recover the secret keys combining the use of the active noninvasive technique attack of clock manipulation and Differential Fault Analysis (DFA) cryptanalysis. The attack system is able to inject transient faults into the Trivium in a clock cycle and sample the faulty output. Then, the internal state of the Trivium is recovered using the DFA cryptanalysis through the comparison between the correct and the faulty outputs. The secret key of the Trivium were recovered experimentally in 100% of the attempts, considering a real scenario and minimum assumptions. |
