La confiance dans le routage Ad hoc : étude du protocole OLSR

Abstract : The implicit trust is always present in the operating protocols, in particular, between the entities involved in routing operations. In our work, we are interested by trust management as security solution for OLSR protocol. This approach fits particularly with characteristic of ad-hoc networks. Moreover, the explicit trust management allows entities to reason with and about trust, and to take decisions regarding other entities.

First, we analyse the fonctionning of OLSR protocol under the terms of trust. Then, we propose a trust-based reasoning which allow to each node to evaluate the behavior of the other nodes, to detect misbehavior nodes, and then to be able to trust or not the other nodes. Finally, we propose a solutions of prevention and contermeasures to resolve the situations of inconsistency, and counter the malicious nodes. These solutions require only minor modifications on the OLSR and can be extended depending on the attack type and users needs.
