Multiple fault diagnosis is a challenging problem because the number of candidates grows exponentially in the number of faults. In addition, multiple faults in dynamic systems may be hard to detect, because they can mask or compensate each other’s effects. The multiple fault problem is important, since the single fault assumption can lead to incorrect or failed diagnoses when multiple faults oc...

Algebraic Fault Analysis (AFA) is a cryptanalysis for block ciphers proposed by Courtois et al., which incorporates algebraic to overcome the complexity of manual analysis within context Differential (DFA). The effectiveness AFA on lightweight has been demonstrated. However, systems prevents it from attacking heavyweight efficiently. In this paper, we propose novel called Redundancies-assisted ...

Occurrence of a multiple-points fault in machine operations could result in exhibiting complex fault signatures, which could result in lowering fault diagnosis accuracy. In this study, a multiple-points defect model (MPDM) is proposed which can simulate fault signature’s dynamics for n-points bearing faults. Furthermore, this study identifies that in case of multiple-points fault in the rotary ...

Sosemanuk is a software-based stream cipher which supports a variable key length of either 128 or 256 bits and 128-bit initial values. It has passed all three stages of the ECRYPT stream cipher project and is a member of the eSTREAM software portfolio. In this paper, we present a fault analysis attack on Sosemanuk. The fault model in which we analyze the cipher is the one in which the attacker ...

Rabbit is a high speed scalable stream cipher with 128-bit key and a 64-bit initialization vector. It has passed all three stages of the ECRYPT stream cipher project and is a member of eSTREAM software portfolio. In this paper, we present a practical fault analysis attack on Rabbit. The fault model in which we analyze the cipher is the one in which the attacker is assumed to be able to fault a ...
