Protocoles d’Etablissement de Confiance pour Objets Communicants

With the advent of self-organizing systems such as ad hoc networks or pervasive computing, security protocols have to meet a new requirement for establishing trust among parties that have no a priori relationship such as a shared naming structure or a common organization. Trust establishment in this context calls for a new paradigm with respect to classical scenarios whereby entities build trus...

Couplage de dynamiques, auto-organisation et confiance dans un système multi-agents perturbé

This paper addresses the issue of the self organization of a multi-agents system through the coupling of three dynamics : informational dynamics, behavioral dynamics and their coordination through a retro-active coupling. As an illustrative example, we consider the problem of maintaining information coherence and its robustness in a multi-agent system (MAS) that collectively gathers information...

Corroboration de vues discordantes fondée sur la confiance∗

Résumé. Cet article traite de la corroboration d’informations, dans le contexte de vues exprimant des opinions sur des faits de façon éventuellement contradictoire. Il s’agit de prédire si un fait est vrai ou faux. Des méthodes d’agrégation simples comme le vote donnent déjà de bons résultats, mais nous présentons dans cet article des algorithmes qui tiennent compte de la confiance dans les vue...

Mécanismes légers de gestion de la confiance pour des réseaux de capteurs sans fil

Communication in ad hoc networks, such as Wireless Sensor Networks (WSN), requires the implementation of decentralized algorithms to manage routing. The global issue of such algorithms rely strongly on the correct behavior of nodes. This increases the vulnerability of the system regarding malicious intrusions or local failures. We propose in this article an adaptation of a routing protocol for ...
