Abstract : Multicast communication is an efficient mechanism, adapted to several applications such as video conferences, software distributions ...
The principal advantage of this type of communications is the optimisation of network resources, mainly by reducing the bandwidth and the routers resources consumption.

In parallel to the development of the multicast services within Internet, the last years saw the emergence of the ad hoc networks, due to the appearance of new wireless technologies and new standards (like 802.11, Wimax, ...). An ad hoc network is a dynamic collection of autonomous entities, without any fixed infrastructure, and which can be highly mobile.

The combination of MANETs with the multicast services induces new challenges towards the required security infrastructure, to ensure a reliable deployment of the multicast communications within this wireless environment. In this context we defined two group key management protocols in MANETs, a receivers-oriented protocol called Enhanced BAAL and a sources-oriented protocol named BALADE. We proposed also OMCT: a dynamic clustering algorithm of multicast group that we integrated in BALADE. This coupling ensures an efficient and fast keys distribution, taking into account the mobility and the localization of nodes, while optimizing the energy and bandwidth consumptions. The applicability of BALADE coupled with OMCT is shown through its formal validation with the AVISPA tool, its implementation within a cooperative jukebox application, and the evaluation of its performances under the network simulator NS2.
