Abstract
Abstract
Mobile ad hoc network is a new wireless mobile network does not rely on the
assistance of any infrastructure, without the centre control nodes and limited
calculation resource. The core issue of mobile ad hoc network security mechanisms is
to establish a security, efficient and viable key management system.
In this paper, it researches and analysis the existing mobile ad hoc network group
key agreement and management mechanism in domestic and foreign, and summarizes
the general ideas and methods to the problem of mobile ad hoc network group key
agreement and management. And so, it is proposed that three group key agreement and
management protocols adapt to different network topology: the fully-distributed group
key agreement and management protocol based on Feldman scheme, the distributed
group key agreement and management protocol based on complete binary tree, the
clustering group key agreement and management protocol based on the improved WCA
algorithm. These protocols can resolve the key challenges in system security and
performance when nodes move.
