Available in PDF, EPUB and Kindle. Book excerpt: NOUS PRESENTONS PLUSIEURS CONTRIBUTIONS REALISEES DANS LE CADRE DU DEVELOPPEMENT D'UNE APPROCHE POUR LA VERIFICATION FORMELLE DE SYSTEMES PARALLELES. LA PREMIERE CONTRIBUTION EST UN OUTIL THEORIQUE DE MODELISATION, LES GRAPHES ABSTRAITS ANNOTES (GAA). CES OBJETS MATHEMATIQUES PERMETTENT DE MAINTENIR LA SEPARATION ENTRE LA STRUCTURE FINIE DES DESCRIPTIONS ET LEUR CONTENU SEMANTIQUE QUI EST GENERALEMENT INFINI. MALGRE LEUR RELATIVE SIMPLICITE THEORIQUE ILS CONSTITUENT UN MOYEN DE DESCRIPTION PARTICULIEREMENT PUISSANT ET ACCESSIBLE DE NOMBREUSES PROPRIETES SOPHISTIQUEES (E.G. COHERENCE GLOBALE, FRAICHEUR, AUTHENTIFICATION). LA DEUXIEME CONTRIBUTION EST RELATIVE A LA CONCEPTION D'UNE TECHNIQUE DE VERIFICATION PARTICULIEREMENT PUISSANTE QUI PERMET D'EXPLOITER L'ORDRE PARTIEL DES EVENEMENTS POUR REDUIRE A LA FOIS LA COMPLEXITE DE L'EXPRESSION D'INVARIANT ET CELLE DE LA VERIFICATION. LA TROISIEME CONTRIBUTION EST UNE APPLICATION AU DOMAINE DE LA VERIFICATION DES PROTOCOLES D'AUTHENTIFICATION. L'APPROCHE SEPARE LA MODELISATION DES CONNAISSANCES, DE LA MODELISATION DE NOTIONS DE NATURE TEMPORELLE COMME LA FRAICHEUR. CETTE APPROCHE EST ILLUSTREE POUR LA VERIFICATION D'UN PROTOCOLE D'AUTHENTIFICATION PARTICULIEREMENT REPRESENTATIF, CELUI DE NEEDHAM-SCHROEDER. LA QUATRIEME CONTRIBUTION EST UNE THEORIE SEMANTIQUE POUR L'UNIFICATION DES PARADIGMES DE PROGRAMMATION PARALLELE, FONCTIONNELLE ET IMPERATIVE. NOTRE THEORIE SEMANTIC EST COMPOSEE ESSENTIELLEMENT D'UNE SEMANTIQUE STATIQUE ET DE DEUX SEMANTIQUES DYNAMIQUES: L'UNE OPERATIONNELLE ET L'AUTRE DENOTATIONNELLE
Book Synopsis Contribution à la vérification d'exigences de sécurité by : Dominique Evrot

Available in PDF, EPUB and Kindle. Book excerpt: L'introduction des nouvelles technologies de l'information et de la communication dans les systèmes automatisés entraîne un accroissement de la complexité des fonctions qu'ils supportent. Cet accroissement de la complexité a un impact sur la sécurité des systèmes. En effet, leurs propriétés ne sont plus réductibles aux propriétés de leurs constituants pris isolément mais émergent d'un réseau d'interactions entre ces constituants qui peut être à l'origine de comportements néfastes et difficiles à prévoir. Notre conviction est que le développement sûr de ces systèmes doit combiner des approches pragmatiques orientées « système », qui tiennent compte du facteur d'échelle réel d'une automatisation pour appréhender le fonctionnement global du système et son architecture, avec des approches plus formelles qui permettent de s'assurer que les propriétés intrinsèques des constituants contribuent efficacement au respect des exigences « système » formulées par les utilisateurs. Le travail présenté dans ce mémoire définit donc une approche méthodologique basée sur le formalisme SysML (System Modeling Language) permettant l'identification, la formalisation et la structuration d'exigences globales relatives à un système, puis leur projection, sous forme de propriétés invariantes, sur une architecture de composants. La vérification des exigences de sécurité, repose alors, d'une part, sur un raffinement prouvé (par theroem proving) des exigences « système » permettant d'établir leur équivalence avec un ensemble de propriétés intrinsèques relatives à chacun des composants, et d'autre part, sur la vérification formelle (par model checking) de ces propriétés intrinsèques.

Book excerpt: LE BUT DE CETTE THESE EST LA VERIFICATION DES PROPRIETES DE SECURITE DE PROGRAMMES PARALLELES. DANS LA PREMIERE PARTIE DE CETTE THESE, NOUS PRESENTONS UN MECANISME DE CONTROLE D'ACCES ET NOUS L'INTEGRONS DANS UN LANGAGE OBJETS-ORIENTES PARALLELE. LA DEUXIEME PARTIE DE LA THESE PRESENTE UN SYSTEME DE PREUVE DE SECURITE POUR UN LANGAGE PARALLELE. CE SYSTEME EST UTILISE POUR VERIFIER QU'IL N'EXISTE PAS DE FUITE D'INFORMATIONS ILLEGALE ENTRE LES VARIABLES D'UN PROGRAMME. NOUS ADAPTONS CE MECANISME EN UNE VERSION POUR UN COMPILATEUR AINSI QU'EN UN MECANISME QUI S'INTEGRE DANS LA MACHINE D'EXECUTION DU LANGAGE. CE DERIER MECANISME VERIFIE LES PROPRIETES DE FUITE D'INFORMATIONS PENDANT L'EXECUTION DU PROGRAMME. ENFIN DANS LA TROISIEME PARTIE DE LA THESE, NOUS PRESENTONS UN MECANISME QUI S'INTEGRE DANS LE SYSTEME D'EXPLOITATION QUI VISE A EMPECHER DES ACCES ILLEGAUX AUX DONNEES DE PROGRAMMES.

Book excerpt: Weaponry is a central factor in any kind of military activity. The incorporation of weapon systems into aircraft and their integration and satisfactory operation is a topic of major importance to armed forces and manufacturers of weapons and aircraft alike. The scope of this symposium was to critically review the overall state-of-the-art in aircraft weapon system compatibility and integration and to illuminate possible paths for future development and provide beneficial ideas and experience. Sessions dealt with the following topics: Theoretical methods and modelling techniques, Experimental and flight test techniques, Integration processes and programmes, Addressing future challenges. This symposium produced many excellent papers providing broad coverage of the weapons integration issues. There were many common threads with regard to the analysis, wind tunnel testing, and flight testing. Computational fluid dynamics (CFD) is proving to be a useful technique; wind tunnel testing is very important in the weapons integration process; but, flight testing has to be the final phase of the weapons integration process. This symposium produced a level of cohesiveness between the analysts and testers; however, full agreement as to the mix of analysis and testing did not evolve. In order to reduce the cost of weapon integration, certification, clearance, and flight testing, weapon integration analytical techniques, including CFD and wind tunnel testing, and flight testing need to become more of an integrated process. The knowledge gained and information shared at this symposium should assist the participants in developing a more integrated process in order to provide NATO nations with fully integrated weapon systems at an affordable price.
