We present a novel approach for analysing the propagation of data errors in software. The concept of error permeability is introduced as a basic measure upon which we define a set of related measures. These measures guide us in the process of analysing the vulnerability of software to find the modules that are most likely exposed to propagating errors. Based on the analysis performed with error...

We present an application for the simulation of errors in storage systems. The software is completely parameterizable in order to simulate different types of disk errors and disk array configurations. It can be used to verify and optimize error correction schemes for storage. Realistic simulation of disk errors is a complex task as many test rounds need to be performed in order to characterize ...

This paper addresses the issue of characterizing the respective impact of fault injection techniques. Three physical techniques and one software-implemented technique that have been used to assess the fault tolerance features of the MARS faulttolerant distributed real-time system are compared and analyzed. After a short summary of the fault tolerance features of the MARS architecture and especi...

This paper discusses the problems of pin-level fault injection for dependability validation and presents the architecture of a pin-level fault injector called RIFLE. This system can be adapted to a wide range of target systems and the faults are mainly injected in the processor pins. The injection of the faults is deterministic and can be reproduced if needed. Faults of different nature can be ...

This paper experimentally evaluates and models the error-caused security vulnerabilities and the resulting security violations on two Linux kernel firewalls: IPChains and Netfilter. There are two major aspects to this work: to conduct extensive error injection experiments on the Linux kernel and to quantify the possibility of error-caused security violations using a Stochastic Activity Network ...

Analyzing and evaluating the sensitivity of embedded systems to soft-errors have always been a challenge for aerospace or safety equipment designer. Different automated fault-injection methods have been developed for evaluating the sensitivity of integrated circuit. Also many techniques have been developed to get a fault tolerant architecture in order to mask and mitigate fault injection in a c...

2 ANN Classifiers The noise injection into the training samples has been shown to lead to improvement of the generalization ability of artificial neural network(ANN) classifiers. In this paper, we investigate the positive effect of the noise injection on the generalization ability of ANN classifiers in high dimensions. We further show that the noise injection technique is very useful in situati...
