Fonction Physique Non-clonable pour la Sécurité du Cycle de Vie d'un Objet Cyber-physique

Abstract : The thesis focus on the conception of solutions to secure, all along its lifecycle, the assets and the functions which are embedded into a connected object. The lifecycle induces multiple interactions which expose the assets. Still, each actor may need private access in order to perform technical operations which have to be done. The solution has to securely manage the access requests but also takes account of the fact that most of the connected object are resources constraints system.We provide two main contributions: the analysis of security requirements for the device lifecycle and a new model of extraction circuit for strong digital PUF. The identified configuration for the extraction circuit offer trade-off between the circuit area, the frequency and the security metrics. It allows to conceive an efficient DPUF which could be integrated at fabrication chip, ensuring authentication property and performance requirements for lifecycle.
