Available in PDF, EPUB and Kindle. Book excerpt: The emergence of wireless sensor networks (WSNs) open the way with a multitude of fields of research constituting the privileged seats of their deployment. WSNs consist of small nodes with sensing, computation, and wireless communication capabilities and expected to play an essential role in the upcoming age of pervasive computing. Due to their constraints in computation, memory, power resources, and its deployment in unattended and hostile environments, individual sensors are vulnerable to security compromise and susceptible to physical capture. Furthermore using wireless communications makes security a challenge in these networks. As a result, security must be an important factor to have in mind when designing WSNs. In this book, we present a study of wireless sensor networks, security problem in these networks, we present also a state-of-the-art of key management protocols, as consequence we propose a new protocol for key management.

Available in PDF, EPUB and Kindle. Book excerpt: Les applications des réseaux de capteurs sans fil se diversifient avec l'apparition de capteurs miniatures et performants. Le projet ANR CAPTEURS s'intéresse aux réseaux de capteurs sans fil appliquées à la supervision de la chaîne du froid. L'utilisation de la communication sans fil, l'absence d'entité de confiance, la diversité des organismes produisant et gérant les capteurs, ainsi que le souci d'économiser les ressources énergétiques des capteurs nous a conduits à concevoir et implémenter un nouveau protocole de sécurité visant essentiellement à authentifier les échanges entre capteurs. L'objet de ce travail est, en premier lieu, la conception et l'implémentation d'un protocole de sécurité et en second lieu le test de cette solution intégrée avec Placide, le protocole de gestion du réseau. Le protocole de sécurité est composé essentiellement de deux phases : une phase de négociation des clés de paires entre les capteurs qui a été intégrée dans la phase d'initialisation du protocole Placide, et la phase de régime permanent au cours de laquelle les paquets sont authentifiés (le chiffrement des données étant optionnel).

Available in PDF, EPUB and Kindle. Book excerpt: Les réseaux de capteurs sans fil (RCSF) sont devenus un thème porteur aussi bien pour la recherche académique que pour les activités des services de R&D en raison de leur simplicité de déploiement et de leur potentiel applicatif dans des domaines très variés (militaire, environnemental, industriel). Un RCSF est composé d'un ensemble de noeuds devant être opérationnels et autonomes énergétiquement pour de longues périodes. De ce fait ils sont limités en capacité mémoire et de calcul, et contraint à exploiter une faible puissance de transmission, ce qui en limite leur portée et rend leur débit modeste. Le besoin de sécuriser les communications dans un RCSF dépend de la criticité des données échangées pour l'application supportée. La solution doit reposer sur des échanges sûrs, confidentiels et fiables. Pour assurer la sécurisation des échanges, des techniques de cryptographie existent dans la littérature. Conçues à l'origine pour des réseaux informatiques majoritairement câblés, elles se basent généralement sur des algorithmes complexes et gourmands en ressource. Dans le cadre de cette thèse, nous avons proposé, implémenté et évalué une architecture sécurisée et dynamique adaptée aux communications des RCSF. Elle permet de garantir et de maintenir la sécurité des communications durant toute la durée de vie d'un réseau multi-saut. Nous avons utilisé et adapté des algorithmes standards de cryptographie, tels que AES-CTR et la suite d'algorithmes basée sur ECC, qui permettent à notre architecture de résister à la majorité d'attaques. Nous avons quantifié le surcoût en temps de calcul et en occupation mémoire de notre solution. Les résultats d'implémentation de notre proposition sont issus de mesures réelles faites sur une maquette réalisée à partir de cartes TelosB.

Available in PDF, EPUB and Kindle. Book excerpt: Wireless Sensor Networks have recently emerged as an important field of research. Due to the cheap network configuration, data collection in wide range and self-organization without infrastructure, these networks will be widely used in diverse domains such as military, environmental, health and industry. Security is an essential requirement for many sensor network applications. Providing security to small sensor nodes is challenging due to limited capabilities of sensor nodes in terms of storage, computation, communication and energy. Moreover, some WSN characteristics complicate the design of a key management scheme such as the vulnerability of nodes to physical attack due to the deployment in hostile area where the attacker can simply compromise any node and then reveal its security materials (i.e. keys, functions,..etc). An efficient key management scheme should offer a high resistance degree with limited/small key storage overhead and it must respect the energy-supplied constraint of the sensor. In this thesis we first review and classify the most of the up to date representative WSN key management schemes and compare them using three evaluation metrics. We then propose two new key management scheme to overcome the problem of trade-off between the number of keys stored per node and the resistance against the compromised nodes. The first, called A Tow Level Architecture for Key Management in Wireless Sensor Networks (TLA), combines efficiently two key management techniques. The second, called Hierarchical kEy management pRotocol for heterOgeneous wireless sensor networks (HERO), uses the probabilistic key pre-distribution. We then propose a mathematical model of the node capture attack impact on key management schemes for HWSN. Finally, we conclude this dissertation with some concluding remarks and highlight future work.

Download or read book Mobile Wireless and Sensor Networks written by Amine Dahane and published by CRC Press. This book was released on 2019-07-01 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless networking covers a variety of topics involving many challenges. The main concern of clustering approaches for mobile wireless sensor networks (WSNs) is to prolong the battery life of the individual sensors and the network lifetime. For a successful clustering approach, the need of a powerful mechanism to safely elect a cluster head remains a challenging task in many research works that take into account the mobility of the network. In Mobile, Wireless and Sensor Networks: A Clustering Algorithm for Energy Efficiency and Safety, the authors use an approach based on computing of the weight of each node in the network as the proposed technique to deal with this problem. They present a virtual laboratory platform (VLP) of baptized mercury, allowing students and researchers to make practical work (PW) on different aspects of mobile wireless sensor networks. The authors’ choice of WSNs is motivated mainly by the use of real experiments needed in most college courses on WSNs. These usual experiments, however, require an expensive investment and many nodes in the classroom. The platform presented here aims at showing the feasibility, the flexibility, and the reduced cost using the authors’ approach. The authors demonstrate the performance of the proposed algorithms that contribute to the familiarization of the learners in the field of WSNs. The book will be a valuable resource for students in networking studies as well as for faculty and researchers in this area.

This book was released on 2010 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse a pour objectif d'étudier des solutions susceptibles d'assurer la sécurité dans les réseaux de capteurs sans fil. Après avoir présenté l'état de l'art du domaine, cette thèse s'articule autour de trois grandes parties. La première partie propose des solutions algorithmiques pour la sécurité des réseaux de capteurs. Deux mécanismes dédiés permettant de détecter deux attaques particulières de ces réseaux sont proposés. Il s'agit d'une première solution permettant de détecter l'attaque. La deuxième solution permet de détecter l'attaque de réplication de nœuds en se basant sur une approche hiérarchique. La deuxième partie se concentre sur des solutions fondées sur l'utilisation de la cryptographie symétrique. Ainsi, un premier protocole de gestion clés et de contrôle d'accès est proposé. Son but est de partager une clé commune entre chaque paire de nœuds présents dans le réseau. Dans un deuxième temps, nous nous sommes intéressés à la sécurisation de l'agrégation des données. Plus précisément, nous proposons deux mécanismes fondés sur sur les fonctions de hachage universelles permettant d'agréger des preuves d'intégrité des données transmises afin de permettre au puits de vérifier l'intégrité des données agrégées. Dans une troisième partie, alors que la diversité des solutions de sécurité permet de définir des politiques de sécurité capable d'assurer des propriétés bien définies, nous présentons une démarche de modélisation formelle permettant de simuler et d'évaluer l'impact des politiques de sécurité sur la consommation énergétique d'un réseau. Le but est ici d'évaluer l'impact en terme d'énergie du passage d'une politique à une autre, ce qui nous permettra ensuite de mieux gérer par exemple la durée de vie d'un réseau de capteurs.
