Abstract: In the fast growing wireless network and mobile technology, we have experienced several group based services. Group key management is an essential building function for secure multicast architecture. The existing GKM-Group Key Management Services accomplish to establish the communication within a single group and it may not fit into multiple multicast group circumstances because of inadequate use of keys. The rekeying overheads are occurred in GKM approach. In the suggested approach, the Master Key Encryption based MGKM Scheme will reduce the releasing overheads from managing multiple group key. The Key Distribution Center will generate the master key and multiple slave keys will be generated depending upon the group added or removed. This will increase the data security, where the authorized user can access data and unauthorized user may not able to access the data.
