ECGK: An efficient clustering scheme for group key management in MANETs (Kaouther Drira, Hamida Seba, Hamamache Kheddouci)
Abstract
Mobile Ad hoc NETworks (or MANETs) are
flexible networks that are expected to support emerging group
applications such as spontaneous collaborative activities and
rescue operations. In order to provide secrecy to these
applications, a common encryption key has to be established
between group members of the application. This task is critical
in MANETs because these networks have no fixed
infrastructure, frequent node and link failures and a dynamic
topology. The proposed approaches to cope with these
characteristics aim to avoid centralized solutions and organize
the network into clusters. However, the clustering criteria used
in the literature are not always adequate for key management
and security. In, this paper, we propose, a group key
management framework based on a trust oriented clustering
scheme. We show that trust is a relevant clustering criterion for
group key management in MANETs. Trust information enforce
authentication and is disseminated by the mobility of nodes.
Furthermore, it helps to evict malicious nodes from the
multicast session even if they are authorized members of the
group.
