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 ...

In [15], Li et al. firstly proposed a differential fault analysis on ARIA-128. This attack requires average 45 random byte fault injections. In 2012, Park et al. proposed the improve DFA by using 33 random byte fault injection. Also Kim proposed differential fault analysis based on multi byte fault model. In this model, the number of fault injections is reduce to 13 and If access to the decrypt...

We present a study of several fault attacks against the block cipher IDEA. Such a study is particularly interesting because of the target cipher’s specific property to employ operations on three different algebraic groups while not using substitution tables. We observe that the attacks perform very different in terms of efficiency. Although requiring a restrictive fault model, the first attack ...

Security of cryptographic circuits is a major concern. Smartcards are targeted by sophisticated attacks like fault attacks that combine physical disturbance and cryptanalysis. We propose a methodology and a tool (PAFI) to analyse the robustness of circuits under fault attacks using fault injection in simulation. The number of injection is reduced by taking into account the function of the latch...

This paper presents a parametric low differential order model, suitable for mathematically analysis for Induction Machines with faulty stator. An adaptive Kalman filter is proposed for recursively estimating the states and parameters of continuous–time model with discrete measurements for fault detection ends. Typical motor faults as interturn short circuit and increased winding resistance ...

In this work, we analyze all existing RSA-CRT countermeasures against the Bellcore attack that use binary self-secure exponentiation algorithms. We test their security against a powerful adversary by simulating fault injections in a fault model that includes random, zeroing, and skipping faults at all possible fault locations. We find that most of the countermeasures are vulnerable and do not p...

This work exploits internal differentials within a cipher in the context of Differential Fault Analysis (DFA). This in turn overcomes the nonce barrier which acts as a natural counter-measure against DFA. We introduce the concept of internal differential fault analysis which requires only one faulty ciphertext. In particular, the analysis is applicable to parallelizable ciphers that use the cou...
