No. of bitstreams: 1 Flavio dos Santos Oliveira.pdf: 1896504 bytes, checksum: 45cbf62efa70089369e36462e0cec199 (MD5) Previous issue date: 2012-06-29 / Após a Revolução de 1930, muitos cachoeirenses tiveram frustradas suas expectativas de maior representatividade política. A rearticulação dos interesses oligárquicos no Partido Social Democrático e no Partido da Lavoura suprimiu ao mínimo os acessos democráticos ao Aparelho de Estado. É nesse contexto de exclusão e frustração com os caminhos da vida política após a Revolução de 1930 que a AIB funda em 1935 o núcleo integralista de Cachoeiro de Itapemirim. Aí aela encontra um conjunto de fatores favoráveis ao seu crescimento. No Espírito Santo, ela encontrara terreno fértil para sua expansão, sobretudo, nas regiões de colonização italiana. Apesar de Cachoeiro de Itapemirim não ser um município de predominante colonização italiana, em muitos distritos e municípios próximos a ela, como Floresta, Castelo, Alegre, Venda Nova do Imigrante entre outros, a presença de italianos era significativa. Nessas regiões, a AIB ostentará toda sua força e organização. Ademais, uma vez que Cachoeiro de Itapemirim era na época o principal centro político-econômico da região Sul, a circulação de idéias e pessoas era muito intensa. Outrossim, a AIB contava com o apoio de um forte aliado, a saber, a Igreja que a apoiava, sobretudo, em sua luta contra o comunismo e a maçonaria. Os integralistas cachoeirenses também se valeram fartamente dos ritos e símbolos integralistas, além dos desfiles e impressos como estratégias de arregimentação e propaganda da Doutrina do Sigma. Com efeito, o crescimento da AIB logo articulará os partidos e movimentos políticos que a precederam numa verdade luta antiintegralista. Pouco tempo após a fundação da AIB em Cachoeiro, a cidade foi palco de um violento conflito. A fim de impedir a realização de um Congresso Integralista na cidade, a Aliança Nacional Libertadora mobilizou uma multidão num grande comício antifascista no campo do Estrela. Em seguida foram para a Estação da Leopoldina para interromper o desembarque da comitiva integralista. Um dia antes, no dia 1° de Novembro de 1935, Alberto Secchin, jovem integralista, havia sido assassinado numa emboscada nas proximidades do Morro Grande. Os integralistas passaram o dia de finados reunidos velando o corpo do companheiro. Os nervos ficaram exaltados. Com isso, aquilo que deveria ser apenas um congresso se tornou um dos conflitos mais controversos e trágicos da História Política de Cachoeiro de Itapemirim / After 1930 s revolution, many citizens of Cachoeiro de Itapemirim have seen their hopes thwarted from greater political representativeness. The rearrangement of the oligarchic interests within the Social Democratic Party and within the Tillage Party worked their way in supressing democratic acess to the minimum forms in the State apparatus. It is in this context of exclusion and frustration that AIB (Brazilian Integralist Action Party) founds, in 1935, the integralist center of Cachoeiro de Itapemirim. There the party finds a set of factors for it s growth. In the state of Espírito Santo, it found good soil for it s expansion, mainly around the italian colonized regions. Even though Cachoeiro de Itapemirim is not a proeminently italian colinized county, in many districts and counties in the vicinities the italian descendencies are numerous, like in Floresta, Castelo, Alegre, Venda Nova do Imigrante and others. In these regions, AIB displays all its power and organization. Furthermore, once Cachoeiro de Itapemirim was by the time a major political and economic centre in the state s south region, the circulation of people and ideas was intense. Thereto, AIB had the support of a strong ally, namely, the Church, above all when it came to be against the communism and the freemasonry. The integralist members from Cachoeiro also employed a lot the integralist symbols and rites, beyond the use of parades and prints as strategies to regimentate and propagate the Doctrine of the Sigma. Indeed, AIB s growth made the former parties and political movements unite themselves in a anti-integralist campaign. Right after AIB s foundation in Cachoeiro, the city became stage of a fierce conflict. The National Freedom Alliance (Aliança Nacional Libertadora) gathered a great cluster in a anti-facist assembly in Estrela Field with the intention of disrupting a integralist congress in the city. After that they went to Leopoldina Station to stop the disembark of a integralist entourage. A day before, november 1st of 1935, Alberto Secchin, a young integralist, have been murdered in an ambush next to Morro Grande. The integralists spent Memorial Day watching their fellow s body. Tension was rising. From this, that with was supposed to be just a congress turned out to be one of the most controversial and tragical conflicts in the politics history of Cachoeiro de Itapemirim

Vers un cloud de confiance : modèles et algorithmes pour une provenance basée sur les contrôles d'accès / Towards a trusted Cloud : models and algorithms for a provenance based on access controls

Lacroix, Julien 07 December 2015 (has links)
Ce document constitue l'aboutissement de trois années de thèse. Après avoir introduit et dégagé la problématique générale se rapportant à mon sujet de thèse, à savoir « comment utiliser les données de provenance pour favoriser un Cloud de confiance ? », je présente une description des concepts, modèles et langages se rapportant à ma thèse et l'état de l'art qui peut répondre en partie à cette problématique. En second lieu, je présente la solution basée sur la provenance que j'apporte aux contrôles d'accès, dans les systèmes distribués comme le Cloud : PBAC². Elle repose sur un système combinant à la fois des modèles de provenance (PROV-DM) et de contrôles d'accès (règles génériques de type RBAC avec des politiques d'embrigadement ou de réglementation). Ce système utilise un moteur d'exécution central appelé le médiateur pour renforcer la sécurité et favoriser la confiance dans le Cloud, via la vérification de règles sur une partie du graphe de provenance rétrospective qu'il a reçue. Par ailleurs, je décris l'étude que j'ai faite de trois extensions de PBAC² : (1) l'intégration de l'ontologie PROV-O et ses avantages et inconvénients quant à la taille du (sous-)graphe de provenance reçu par le médiateur ; (2) la construction de l'adaptation de PBAC² avec l'approche de sécurité qu'est la réglementation; (3) la traduction des règles PBAC² en contraintes PROV-CONSTRAINTS. De plus, PBAC² est appliqué sur un exemple réaliste propre au secteur médical. Un prototype de PBAC² et une démonstration sur des exemples concrets avec une machine locale et un système de Cloud réel illustrent la portée de ce travail. En conclusion de la thèse, je propose quatre perspectives de ce travail. / This document is the culmination of three years of thesis. Having introduced and cleared the general issue related to my thesis subject, i.e. « how to use provenance data to enforce trust in the Cloud? », I present a description of the concepts, models and languages related to my thesis and the state of the art that can partially address this issue. Secondly, I present the solution based on provenance that I bring to access controls, in distributed systems such as the Cloud: PBAC². It is based on a system combining both provenance models (PROV-DM) and access controls (generic rules of RBAC type with regimentation and regulation policies). This system uses a central execution engine denoted the mediator to enforce security and foster trust in the Cloud, via rule checking over a part of the retrospective provenance graph it received. Furthermore, I describe the study I made of three PBAC² extensions: (1) the integration of the PROV-O ontology and its pros and cons regarding the size of the (sub)graph received by the mediator; (2) the construction of the PBAC² adaptation with the regulation security approach; (3) the translation of PBAC² rules into PROV CONSTRAINTS constraints. Moreover, PBAC² is applied to a realistic example that belongs to the healthcare sector. A PBAC² prototype and a demonstration on some practical examples with a local machine and a real Cloud system illustrate the scope of this work. In conclusion of the thesis, I propose four perspectives of this work.
