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 ...

In this research seismicity parameters, repeat times and occurrence probability of large earthquakes are estimated for 35 seismic lineaments in Persian plateau and the surrounding area. 628 earthquakes of historical time and present century with MW>5.5 were used for further data analysis. A probabilistic model is used for forecasting future large earthquake occurrences in each chosen lineament....

In this paper, a new method is proposed for fault location estimation in overhead-cable multi-section transmission lines. This method takes advantage of synchronized samples gathered from both terminals of the line in the time domain. Because of this, it does not need a filter to extract fundamental frequency of the voltages and currents. Thus, it shows a higher accuracy, since it is not influe...

Sarroud Dam is located in the north of Khorasan Razavi Province in the city of Kalat. Being located in a fault zone, it is necessary to inject the cut-off wall. Using remote sensing techniques, geographic information system, Landsat satellite imagery and field observations in this research, it was specified that the dam has been located within the range of the Sarroud Fault. According to this, ...

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...

Differential Fault Analysis (DFA) finds the key of a block cipher using differential information between correct and faulty ciphertexts obtained by inducing faults during the computation of ciphertexts. Among many ciphers AES has been the main target of DFA due to its popularity. DFA of AES has also been diversified into several directions: reducing the required number of faults, applying it to...

A commonly used model for fault-tolerant computation is that of cellular automata. The essential difficulty of fault-tolerant computation is present in the special case of simply remembering a bit in the presence of faults, and that is the case we treat in this paper. We are concerned with the degree (the number of neighboring cells on which the state transition function depends) needed to achi...

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...

In this paper a complete analysis of spot defects in industrial S R A M s will be presented. All possible defects are simulated, and the resulting electrical faults are transformed into functional fault models. The existence of the usually used theoretical memory fault models will be verified and new on,es will be presented. Finally, a new march test detecting all realistic faults, with a test ...
