Abstract: In mobile ad hoc networks, most algorithms are lacking a self-organised grouping mechanism for ensuring the scalability and performance of key management. In this paper, we propose to establish self-healing key distribution to the self-organised group members. For this, a self-organised group establishing algorithm is proposed which requires users interacting with their neighbours. This algorithm locally elects the group manager who is responsible for the establishment, distribution, and management of group keys. After establishing the self-organised group and group manager, the collusion resistance threshold self-healing key distribution will be applied within each group for group key establishment. The elected group manager is responsible for distributing and updating the keys. Then using the established keys, secure communication among the mobile nodes will be performed to provide confidentiality.

Keywords: mobile ad hoc networks; MANETs; certification authority; key management; mobile nodes; self-healing key distribution; self-organised group management; collusion resistance threshold; secure communication; confidentiality; network security.
