Download or read book Les R seaux Wifi S curis written by Ab Eric and published by . This book was released on 2020-08-09 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Au départ, les réseaux informatiques filaires n'étaient pas suffisants pour fournir tous les services, mais avec l'avènement des réseaux informatiques sans fil, le vide initial s'est comblé. Donc on peut dire que les entreprises ont besoin des réseaux informatiques filaires et sans fil pour répondre à tous les besoins des utilisateurs. L'implémentation d'un réseau wifi au sein des entreprises exige l'établissement d'une bonne planification cellulaire basée sur un choix judicieux de l'emplacement des différents points d'accès avec une bonne répartition des canaux utilisés. Ceci permet de réduire au maximum les possibilités d'interférences et garantit, en conséquence, de meilleures performances du réseau. Un réseau wifi bien planifié garantit une meilleure performance en matière du débit, de la mobilité et de la portée. Il reste à mettre en oeuvre une politique de sécurité. Ceci se fait par des techniques avancées effectuant la confidentialité et l'intégrité en cryptant les données par des clés solides et par l'identification et l'authentification des utilisateurs pour interdire l'accès au réseau pour des gens non autorisés. Tout ça pour minimiser au maximum les risques qu'un pirate introduit au réseau, lit et modifie les données. Enfin, il faut savoir que la sécurité totale dans les réseaux n'existe pas. Plus le niveau de sécurité est élevé, moins il sera facile de pénétrer et de trouver des informations confidentielles.

Download or read book Wireless LAN Security in a SOHO Environment written by Christian Wimmer and published by GRIN Verlag. This book was released on 2008-09-17 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bachelor Thesis from the year 2006 in the subject Computer Science - Internet, New Technologies, grade: 1,7, University of Wales, North East Wales Institute, Wrexham, Großbritannien (University of Wales, North East Wales Institute, Wrexham, Großbritannien), language: English, abstract: This paper addresses the theory and reality of Wi-Fi security. It provides an overview of security mechanisms and explains how security works in wireless networks. The most important security protocols that are relevant for small office or home office environments are looked upon in more detail. The security of a real-world wireless network is being tested with freely available tools and popular attacking methods. It is demonstrated that old security protocols can no longer be seen as being secure at all. To create a holistic view the idea of Wi-Fi security is then expanded to include the physical level. A series of experiments provides insight on how to make a network more secure with materials and tools available in every household. A WLAN that is nearly unreachable outside the perimeter does not attract any potential hackers. The paper concludes with recommendations on where to place your access point and what can be done to shield it.

This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les travaux de recherche de cette thèse s'inscrivent dans le cadre de la sécurité par chaos des réseaux locaux sans fil, en particulier les réseaux de capteurs sans fil. L'originalité de cette thèse consiste à proposer des cryptosystèmes à base de chaos plus adaptés aux réseaux de capteurs, en termes de consommation d'énergie, que les algorithmes conventionnels et à réaliser une implémentation sur une plateforme réelle. Nous présentons en premier lieu un état de l'art des réseaux, les menaces, les contraintes limitant le processus de sécurité des informations ainsi que les principales techniques de cryptographie. Nous donnons un aperçu sur la théorie de chaos et nous validons l'aspect aléatoire de plusieurs suites chaotiques par les tests statistiques du NIST. Nous proposons ensuite des nouvelles méthodes de construction de S-Box chaotiques tout en prouvant leur robustesse contre les attaques traditionnelles. Nous proposons enfin un nouvel algorithme de cryptage d'image dédié au réseau de capteurs sans fil. La validation de nos contributions est effectuée par simulation et par des mesures expérimentales sur une plateforme de réseaux de capteurs réels (SensLab).
