As Mobile Ad-hoc NETwork (MANET) has dynamic infrastructure, poor physical security and shared
physical medium, key management is a challenging task. MANET has not fixed structure and so it is of potential
security concern because neighbor nodes cannot be trusted. All the group oriented application like video
conferencing, software distribution within a group and interactive multi-party business session use the multicast
transmission for efficient communication and to save network resources. In many multicast environment, new node
can enter and current node can leave at any time and existing members must have to communicate securely using
multicast key management for MANET. The much apt solution to provide these services like authentication,
confidentiality, integrity and secure multicasting is the establishment of key management protocol.
In this paper, we aim to evaluate an overview of different group key management techniques for MANET like
Enhanced Optimized Multicast Cluster Tree (EOMCT) algorithm, Group Member Authentication Protocol (GMAP)
and an Efficient Rekeying Function Protocol (ERFP).
