Sécurisation adaptative des objets de l'IoT par méthodes logicielles (White box) et combinées (hardware et software)

Abstract : The Internet of Things (IoT) has been on the rise for several years now. Following recent attacks on these systems, studies have shown that most of these devices were not sufficiently secured. The ideal solution to this problem would be to provide security mechanisms on all IoT devices however, this solution is not always achievable.An alternative strategy to secure these systems would be to deploy security services at the edge of the network to bring the security mechanisms as close as possible to unsecured devices.The purpose of this thesis is to design an adaptive security framework for IoT devices relying on security services positioning. This work is divided into three contributions, each of which affects different aspects of our approach.The first contribution provides a strategy for deploying security services that minimizes the cost of deployment. This method expresses our positioning constraints into a graph problem which we suggest solving using graph theory.The second contribution formalizes the service placement problems and models them into an ontology. The latter is then used to solve those problems and to compare their different solutions.The third contribution focuses on security services that implement \textit{whitebox} cryptography. In this contribution, we present a mechanism for anchoring these implementations on an IoT network to prevent code lifting attacks and device theft.Finally, we present an adaptive security framework for IoT objects in which we position all the contributions made during this thesis.
