Securisation D'Un Lien Radio Uwb-IR Paperback - 2014
by Benfarah Ahmed
From the publisher
Du fait de la nature ouverte du canal radio, les communications sans fil souffrent de vulnrabilits srieuses en terme de scurit. Dans mes travaux, je me suis intress particulirement deux classes d'attaques savoir l'attaque par relais et l'attaque par dni de service (brouillage). La technologie de couche physique UWB-IR a connu un grand essor au cours de cette dernire dcennie. L'objectif de mes travaux est d'exploiter les caractristiques de la couche physique UWB-IR afin de renforcer la scurit des communications sans fil. L'attaque par relais peut mettre dfaut les protocoles cryptographiques d'authentification. Pour remdier cette menace, les protocoles de distance bounding ont t proposs. Dans ce cadre, je propose deux nouveaux protocoles qui amliorent considrablement la scurit des protocoles de distance bounding au moyen des paramtres de la radio UWB-IR. Le brouillage consiste en l'mission intentionnelle d'un signal sur le canal lors du droulement d'une communication. Je propose une technique rendant la radio UWB-IR plus robuste au brouillage. Enfin, je me suis intress au problme d'intgration de la la scurit en suivant l'approche d'embedding.
