Mesh Based Multicast Key Management Scheme in Ad Hoc Networks

This paper proposes a mesh based multicast key management scheme for mobile ad hoc networks. Among multicast group, these physically more secure and subjectively more trustworthy members form a mesh and use threshold cryptography to share the responsibility and provide group key services with strong security and high availability. Adaptive policy and a token mechanism are introduced to avoid the confliction during the group key updating. The analysis shows that the scheme has perfect security and efficiency
