Abstract. Manet security has a lot of open issues. Due to its characteristics, this kind of network needs preventive and corrective protection. In this paper, we focus on corrective protection proposing an anomaly IDS model for Manet. The design and development of the IDS are considered in our 3 main stages: normal behavior construction, anomaly detection and model update. A parametrical mixture model is used for behavior modeling from reference data. The associated Bayesian classification leads to the detection algorithm. MIB variables are used to provide IDS needed information. Experiments of DoS and scanner attacks validating the model are presented as well.

-In this paper, we discuss open issues regarding certification, auto-configuration and authentication of routing messages for mobile ad-hoc networks (MANET). We describe and discuss existing models for these operations and highlight their specific problems. Considering routing protocols usage, we propose new solutions based on protocol modifications and distributed certifications that can be integrated to establish trust relationships for MANET operation and utilization.

In this paper, we discuss about certification, authentication, auto configuration and routing for mobile ad hoc networks (MANETs). The proposal is based on the works of [1] and [3]. We describe distributed certification, MAE authentication, auto configuration process and routing protocols. Then, we show some problems of these models and we propose some solutions considering routing and others protocol modifications.
