Abstract : New organization models for networks and routing and as well as new services appear due to increasing dynamics within Internet: multicast services, peer-to-peer services, ad hoc and sensor networks. This is partly explained by the convergence of fix and mobile networks, of telecommunications and Internet worlds. The set of contributions presented in the manuscript points out how we have taken into account the dynamic aspect provided by networks and services that we are currently used within Internet. We have worked on management of dynamics networks and we are focused on an important axis of their development, namely the security functional area. In the first part, we study how to adapt protocols to the requirements of the applications at the transport and network level. We show how our work related to ALF (Application Layer Framing) has led us to investigate the active networks paradigm and, more specifically, the management of these active networks. The second part is dedicated to a specific management service, i.e. the security service in the context of group communication. The multicast environment is an excellent application domain, which offers high of dynamics: every member may leave or join its group at every time. This involves frequent rekeying and leads to extensibility problems.
Our research work has resulted in defining new key distribution protocols suitable for
group communication. Aside with the deployment of wireless networks, the need for creating and interconnecting autonomous and spontaneous networks, so-called ad hoc networks, is increasing. Integrating multicast in such networks is important, in particular for military applications or public security operations where group communications are formed in order to exchange confidential data information. These applications are very sensitive and require a high level of security. In this context, we present how we have adapted our group key management protocols to the ad hoc environment. We also propose a new key distribution approach in MANETs (Mobile Ad hoc NETworks) dedicated to secure flow multicast communications according to the sequential multi-source models.
