This paper mainly analyses the fault tolerant capability of a combining classifier that uses a K-voting strategy for integrating binary classifiers. From the point view of fault tolerance, we discuss the influence of the failure of binary classifiers on the final output of the combining classifier, and present a theoretical analysis of combination performance under three fault models. The resul...

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...

Very few differential fault attacks (DFA) were reported on Grain-128 so far. In this paper we present a generic attack strategy that allows the adversary to challenge the cipher under different multi-bit fault models with faults at a targeted keystream generation round even if bit arrangement of the actual cipher device is unknown. Also unique identification of fault locations is not necessary....

Making predictions about the longevity of the single stuck-at fault model is a highly speculative yet nonetheless popular activit y in the IC test community, and has been for years. Despite the welldocumented analytical shortcomings of the SSA fault model as a physical model for defects, SSA fault coverage has yet to be replaced as the standard for test qualit y measurement. How can this be?

Long-term services that operate reliably are hard to construct. In this paper, we argue that for long-term services we need a stronger service property called Healthy-WriteImplies-Correct-Read (HWICR): once a value is written in a healthy period (i.e., when the system’s fault assumption is not violated), the value is correctly read despite intervening unhealthy periods. To build services with t...

In this brief contribution, we derive an exact expression for (n 1)-cube reliability in an n-cube using a new probability fault model and M existing random fault model. Approximate results are also obtained for m-cube reliability for values of m smaller than n I . We show that the proposed probability model for computing subcube reliability is equally accurate, but computationally more efficien...

This paper addresses the design of an observer-based fault diagnosis scheme, which is applied to some of the sensors and actuators of a wind turbine benchmark model. The methodology is based on a modified sliding mode observer (SMO) that allows accurate reconstruction of multiple sensor or actuator faults occurring simultaneously. The faults are reconstructed using the equivalent output err...

In this paper we study a parity check based countermeasure proposed by Chen et al. that thwarts their attack by detecting byte fault injection during the AES key schedule process. We provide a generalization of their approach that allows to derive parity equations for every AES sizes not given by the authors. We analyze why Chen et al. countermeasure does not properly works. Doing so we are abl...

This paper presents efficient methods for online fault detection and diagnosis of Network-on-Chip (NoC) switches. The fault model considered in this research is a system level fault model based on the generic properties of NoC switch functionality. The proposed method is evaluated by fault simulation in a platform using this system level fault model. The experimental results show that with a re...
