GROUP KEY MANAGEMENT FOR MULTICAST STRUCTURES TO IMPROVE SECURED DATA ACCESS
Main Article Content
Abstract
Abstract: In the growing rapidly wireless network and mobile technology, we have one of the sophisticated techniques is multiple group key management. Group key is important functions that will provide enhance better security for multiple multicast structures. The existing system performs to make the communication within a single group and it could not fix the multiple multicast group instances because of insufficient amount of keys. The rekeying overheads are the main problem in GKM method. In the suggested new method of system, the Master Key Encryption based MGKM Scheme will minimize the releasing problem from managing multiple group key. The Key Distribution Center will generate the master key. Multiple slave keys may be generated depends upon the group key added or deleted. This will increase the data security and authorization in a better way, this will enable the access only for the authorized user to retrieve the information and restrict the access for any unauthorized users to access the information.
