A fault attack consists in inducing hardware malfunctions in order to recover secrets from electronic devices. One of the most famous fault attack is Bellcore’s attack against RSA with CRT; it consists in inducing a fault modulo p but not modulo q at signature generation step; then by taking a gcd the attacker can recover the factorization of N = pq. The Bellcore attack applies to any encoding ...

Systems with high dependability requirements are increasingly relying on complex on-line fault management systems to function in a wide range of scenarios. Fault management systems involve a combination of multiple steps – monitoring, data analysis, planning and execution – that are typically independently developed and optimized. We argue that it is inefficient and ineffective to improve any p...

The gearbox is a complicated rotating machinery equipment, in order to realize the gearbox fault early detection and prevention, it is the key to carry out the online diagnosis. This paper used the adaptive variable step-length natural gradient blind source separation algorithm to realize the helicopter gearbox meshing vibration signal and fault vibration signal effective separation. Through th...

We consider a fault tolerant broadcast network of n processors each holding one bit of information. The goal is to compute a given Boolean function on the n bits. In each step, a processor may broadcast one bit of information. Each listening processor receives the bit that was broadcast with error probability bounded by a fixed constant . The errors in different steps, as well as for different ...

Abstract Fault modeling has become an integral element of reservoir simulation for structurally complex reservoirs. Modeling faults in general major implications the grid. In turn, grid quality control is very important order to attain accurate results. We investigate dynamic effects using stair-step (SSG) and corner-point (CPG) approaches fault from perspective performance forecasting. have pe...

The aim of the Fault2SHA European Seismological Commission Working Group Central Apennines laboratory is to enhance use geological data in fault-based seismic hazard and risk assessment promote synergies between providers (earthquake geologists), end-users decision-makers. Here we Database where geologic are provided form characterized fault traces, grouped into faults main faults, with individ...

We study the problem of broadcasting in point-to-point networks with faulty links. The usual approach in which the number of faulty links in each step is bounded by a fixed constant does not reflect the intuition that the probability of a certain link to fail while transmitting a particular message is a fixed constant. In our model the number of faulty links in a given step depends on the total...

Graph of a Process is a causal graph with directly incorporated faults. Edges of a GP can be labelled with signs of influence. In this paper GP is used to analyse system diagnosability. First step is an analysis of redundancy. Next fault isolability can be improved considering symptoms signs or sequences of symptoms occurrences. Analysis uses only information included in GP. Appropriate fault i...
