Solutions de sécurité pour l’internet des objets dans le cadre de l’assistance à l’autonomie à domicile

Abstract : Nowdays, the Internet of Things (IoT) represents a major part of our daily lives. IoT includes awide variety of objects integrating sensors and communication modules that facilitate their integration on the internet. These devices observe and measure the state of the real world and connect real life with the virtual world. IoT provides advanced services such as real-time monitoring of environments as industrial, medical, agricultural, and other environments that can be automatically covered and managed. Ambient Assisted Living (AAL) is one of many areas that benefit from IoT. It aims to help older people in their daily routines by providing new assistance services in smart homes to monitor their physiological constants at lower cost to detect possible health degradations. However, despite all the benefits that IoT brings in our daily lives, some may be a real inconvenience. Security issues greatly impede the development and rapid deployment of this technology. The widespread of IoT can only be successful when adequate security of the objects and the used communication networks is adapted. New lightweight and robust mechanisms need to be adapted to counter the threats and attacks to which IoT infrastructure communications are exposed. A first often a prerequisite mandatory step would be the use of authentication mechanisms that provide the services of object authentication and data protection, while being adapted to the capabilities and respecting the limits of objects and communication technologies. In this thesis, our goal is to implement security solutions for IoT in the medical field. For this, we first establish the state of the art of IoT. Subsequently, we address the security challenges faced by the evolution of IoT. We also consider authentication protocols to ensure the security and privacy of users of connected objects. Afterward, we present a first contribution which consists in three new mutual authentication protocols for connected objects with two different communication modes Machine-to-Machine (M2M) and Machine-to-Cloud (M2C), as part of AAL. Validation of security of our proposals was made using the tools AVISPA and ProVerif in addition to the informal analysis. Our second contribution includes a new identification and authentication protocol in the field of RFID technologies to ensure authentication between a reader and RFID tags in order to guarantee patients security and privacy, as part of an RFID medical assistive environment.
