Public ISBD Titre : Contribution to security management in internet of things Type de document : document multimédia Auteurs : Mahmoud Chaira, Auteur ; Sofiane Aouag, Directeur de thèse ; Hadda Cherroun, Directeur de thèse Editeur : Laghouat : Université Amar Telidji - Département d'informatique Année de publication : 2024 Importance : 98 p. Accompagnement : 1 disque optique numérique (CD-ROM) Note générale : Option : Distributed and mobile computing Langues : Anglais Catégories : THESES :10 informatique Mots-clés : Internet of things  Security  Authentication  Confidentiality  Public blockchain  Private blockchain Résumé : The pervasive integration of smart objects via the Internet of Things (IoT) is fundamentally reshaping and revolutionizing our everyday lives. IoT is recognized as a crucial factor for numerous emerging applications across various areas such as healthcare, smart cities, manufacturing, automotive,agriculture, etc. Despite its growing prevalence, the increasing ubiquity of IoT introduces a set of new challenging security risks. The primary concern involves device authentication, particularly given the vast number of connected devices incorporating a variety of types such as sensors, vehicles, drones, etc. Attackers may exploit this vulnerability to gain access to IoT networks. Moreover, IoT devices generate a massive amount of confidential data that needs to be processed autonomously and transmitted without human involvement. This task is beyond the capabilities of conventional centralized security systems. In addition, the constraints posed by network isolation and the number of messages needed to complete the device association phase are identified as the primary limitations in the two latest works. To address these limitations, we have designed an innovative decentralized mechanism that utilizes a hybrid combination of two blockchain types, local and public. This design ensures the authentication of devices before initiating communication and exchanging information among them. Our solution eliminates the isolation among diverse networks, aids in minimizing the number of messages needed for the association phase, and solves the time delay issue introduced by the PoW consensus mechanism employed in public blockchains. We choose to employ the Ethereum blockchain in both its local and public versions for the implementation of our solution. Subsequently, we assessed its performance in comparison to the existing literature. The results we obtained proved its efficiency in terms of both execution time and energy consumption, considering the same metrics utilized in the most recent works. note de thèses : Thèse de doctorat en informatique Contribution to security management in internet of things [document multimédia] / Mahmoud Chaira, Auteur ; Sofiane Aouag, Directeur de thèse ; Hadda Cherroun, Directeur de thèse . - Laghouat : Université Amar Telidji - Département d'informatique, 2024 . - 98 p. + 1 disque optique numérique (CD-ROM).
