Texto completoThe presence of communicating embedded systems/IoTs in our daily lives have brought a myriad of benefits, from adding conveniences and entertainment, to improving the safety of our commutes and health care. However, the flaws and vulnerabilities in these devices expose their users to risks of property damage, monetary losses, and personal injury. For example, consumer vehicles, both connected and conventional, have succumbed to a variety of design flaws resulting in injuries and death. At the same time, as vehicles are increasingly connected (and in the near future, autonomous), researchers have demonstrated possible hacks on their sensors or internal control systems, including direct injection of messages on the CAN bus.Ensuring the safety of users or bystanders involves considering multiple factors. Conventional safety suggests that a system should not contain software and hardware flaws which can prevent it from correct function. `Safety of the Intended Function' involves avoiding the situations which the system or its components cannot handle, such as adverse extreme environmental conditions. Timing can be critical for certain real-time systems, as the system will need to respond to certain events, such as obstacle avoidance, within a set period to avoid dangerous situations. Finally, the safety of a system depends on its security. An attacker who can send custom commands or modify the software of the system may change its behavior and send it into various unsafe situations. Various safety and security countermeasures for embedded systems, especially connected vehicles, have been proposed. To place these countermeasures correctly requires methods of analyzing and verifying that the system meets all safety, security, and performance requirements, preferably at the early design phases to minimize costly re-work after production. This thesis discusses the safety and security considerations for embedded systems, in the context of Institut Vedecom's autonomous vehicle. Among the proposed approaches to ensure safety and security in embedded systems, Model-Driven Engineering is one such approach that covers the full design process, from elicitation of requirements, design of hardware and software, simulation/formal verification, and final code generation. This thesis proposes a modeling-based methodology for safe and secure design, based on the SysML-Sec Methodology, which involve new modeling and verification methods. Security modeling is generally performed in the last phases of design. However, security impacts the early architecture/mapping and HW/SW partitioning decisions should be made based on the ability of the architecture to satisfy security requirements. This thesis proposes how to model the security mechanisms and the impact of an attacker as relevant to the HW/SW Partitioning phase. As security protocols negatively impact performance, it becomes important to measure both the usage of hardware components and response times of the system. Overcharged components can result in unpredictable performance and undesired delays. This thesis also discusses latency measurements of safety-critical events, focusing on one critical to autonomous vehicles: braking as after obstacle detection. Together, these additions support the safe and secure design of embedded systems

Texto completoIn our dissertation, we question the impact of both international terrorism and security measures on the behavior of the users of the global air transportation network. Using an econometric model, we analyze a new database, AirNetTerror, which contains data on all international passenger flows toward the U.S. from 1990 to 2006 as well as the events of international terrorism by country for the same period. The relevance of our research is twofold. On the one hand, our investigation regarding air travelers’ behavior and their possibilities of modifying their itinerary in light of international terrorism has – so far as we know – never been studied. On the other hand, as we analyze passenger flows from the perspective of the network, we propose a dynamic representation of the impact of travelers’ behavior changes related to terrorist threats and security measures. In particular, taking into account the interdependent security that rules the global air transport network, allows us to question the existence of failures in security measures. Our results underline a significant impact of both international terrorist events and security measures. Furthermore, we locally observe itinerary modifications of travelers that are linked to the previous phenomena. Thus, the combined effect of terrorist threats and security measures seems to lead to equilibrium breaks – that are limited but real – in passenger flows of the global air network. Our thesis offers a different representation of the impact of international terrorism on air transport by placing the traveler’s behavior at the center of the strategic interactions between security actors and terrorists

Texto completoBeryllium will be used as a plasma-facing material for the ITER vacuum vessel. Due to high plasma fluxes, significant amounts of hydrogen isotopes could be retained in the beryllium walls. From the safety point of view, it is important to assess the capability of devices which will be used to limit the tritium inventory in the tokamak in nominal conditions and secondly, to predict the behaviour of tritium in case of accident. The objective of this work is to evaluate within the framework of the Density Functional Theory the behaviour of tritium in beryllium in terms of retention and desorption mechanisms. Firstly, the stability of point defects in beryllium has been evaluated and compared to experiments. Vacancies are shown to be the dominant defect in beryllium. Then, the most stable interstitial sites for tritium atoms and the most favorable migration pathways have been determined. This study has been extended to multiple-trapping phenomenon in monovacancy, in which up to five atoms can be trapped. These data have been used in a kinetic Monte-Carlo code to calculate the diffusion coefficient of tritium and a reaction-diffusion based model, which provides a good agreement with experimental thermal desorption spectra made at IEK-4 (Jülich -- Germany). The emergence of desorption peak at low temperature under high fluence could be explained by the hydride formation

Texto completoA free-standing (i.e. placed on the ground and not anchored) structure can be found in severalindustrial facilities during maintenance operations, in storage halls, etc. During an earthquake,these stacks are likely to rock, slide or overturn. Thus, one of the main concerns regarding theseismic risk studies is to assess and limit, as the case may be, their excessive movements (due tosliding or overturning) to avoid impacts with the surroundings. In this work the earthquake responsesof a free standing stacked structure composed of three pallets intended to store packagesare investigated.The study of the seismic behavior of free-standing structures is known to be a quite challengingtask. Indeed, this problem involves several difficulties due to the large displacements, largerotations and also impact and friction nonlinearities. This implies an extreme sensitivity of theirseismic responses to small perturbations, both experimentally and numerically. Therefore, to analyzeand to predict how they respond under seismic excitation, probabilistic approaches are necessary.First of all, in order to have a quick estimate of the seismic response of the stack taking intoaccount the predominant physical phenomena that take place under unidirectional excitation, asimplified four degrees of freedom analyticalmodel, inspired fromliterature, has been developed.Then, different finite element models, more or less refined, have also been implemented. At thesame time, a comprehensive experimental campaign has been performed on an unidirectionalshaking table of the CEA / Saclay. These experimental results allow us to (i) validate the numericalmodel and (ii) identify the sensitivity of seismic responses (both experimental and numerical).Both approaches - numerical and experimental - combined with probabilistic approacheswere carried out simultaneously during this work and highlight several phenomena. A deterministicapproach identified the consequences of the uplift of the structure on the global behavior :the « fundamental » frequency mode is higher in the rocking phase than in the full contact phase.This work also showed that the adjustment of the dynamic properties of the models is an essential,but delicate task, to obtain an adequate nonlinear response. This means that it will be difficultto know a priori what will be the dynamic properties of the structure. Nevertheless, the simplifiedanalytical model can be used to quickly evaluate the models’sensitivity in relation to the mainphysical parameters, although the sensitivity is not necessarily comparable from one model toanother. In addition, as it is often noted with industrial structures, the seismic tests have shownthat the motion of the stacking was not purely 2D even under an unidirectional excitation. Consequently,defects have been introduced in the models and the numerical results showed an overallsatisfactory agreement by comparison with experimental results. A probabilistic analysis of thedynamic behavior of stacking, entirely conducted in a reliability context and based on the calculationof three usual reliability indicators (the failure probability and the Cornell and Hasofer-Lindreliability index), confirms the deterministic results obtained for each of the seismic excitationsconsidered (uni, bi and tridirectional). However, this effect is less marked for bi and tridirectional excitations

Texto completoThe integration of complex mechanical systems subject to stringent vibration environments requiresconsideration of the real conditions of use from the beginning of the design phase.The thesis shows that the vibration environment and the duration of exposure to this environmentdepend on the use of the system throughout its life cycle. The evaluation of its use is based on thejoint evolution of both the user behavior and the system technology development.The dependability analysis of a complex mechanical system leads to consider the system as a wholeand thus to investigate in depth the dynamic behavior of critical components. A basic modeling ofthe mechanical system allows to qualitatively and quantitatively identify key dynamic behaviors anddetermines the vibration loads to which selected critical components are subjected. On this basis,modeling the behavior of a mechanical component leads to assess its fatigue damage. This indicatorhelps the designer in his choice of component geometry.Finally, the climatic environment as well as effects related to the internal functioning of the system,have been taken into account by performing vibro-climatic tests of on an operating systems, i.e. a fuelcell system integrated into a hydrogen electric vehicle. This helped to develop a procedure to supportthe design of complex mechanical systems

Texto completoWith the eyes of the whole of the doctrines, the penal responsibility was always regarded as the only base for the French criminal law. The concept of dangerous statute, often presented primarily under its pre-criminal aspect, reduced to categories of infringements (infringements obstacles), and to certain types of delinquent (alcoholic dangerous, mental lunatics etc) thus does not seem a base of the French repressive system. With looking there closely however, this thesis does not resist the analysis. Indeed, the study of the concept of dangerous statute approached under its criminal and post-criminal aspect makes it possible to check with which point this concept seems one of the essential bases of the French criminal law. Implicit base certainly, because of the silence of the legislator on this subject, but undeniable base. Contrary to the thesis more revenue, the role of the dangerous statute appears not only at the stage of the choice and the execution of the sorrow, but also at the time of the research of the culpability. Far from being opposed or being excluded, the dangerous statute and the penal responsibility are as complementary as the sorrow and the measurement of safety
Djahel, Soufiene. "Secure routing and medium access protocols in wireless multi-hop networks". Thesis, Lille 1, 2010. http://www.theses.fr/2010LIL10094/document.
Texto completoWhile the rapid proliferation of mobile devices along with the tremendous growth of various applications using wireless multi-hop networks have significantly facilitate our human life, securing and ensuring high quality services of these networks are still a primary concern. In particular, anomalous protocol operation in wireless multi-hop networks has recently received considerable attention in the research community. These relevant security issues are fundamentally different from those of wireline networks due to the special characteristics of wireless multi-hop networks, such as the limited energy resources and the lack of centralized control. These issues are extremely hard to cope with due to the absence of trust relationships between the nodes.To enhance security in wireless multi-hop networks, this dissertation addresses both MAC and routing layers misbehaviors issues, with main focuses on thwarting black hole attack in proactive routing protocols like OLSR, and greedy behavior in IEEE 802.11 MAC protocol. Our contributions are briefly summarized as follows. As for black hole attack, we analyze two types of attack scenarios: one is launched at routing layer, and the other is cross layer. We then provide comprehensive analysis on the consequences of this attack and propose effective countermeasures. As for MAC layer misbehavior, we particularly study the adaptive greedy behavior in the context of Wireless Mesh Networks (WMNs) and propose FLSAC (Fuzzy Logic based scheme to Struggle against Adaptive Cheaters) to cope with it. A new characterization of the greedy behavior in Mobile Ad Hoc Networks (MANETs) is also introduced. Finally, we design a new backoff scheme to quickly detect the greedy nodes that do not comply with IEEE 802.11 MAC protocol, together with a reaction scheme that encourages the greedy nodes to become honest rather than punishing them
