Secure and efficient transmission in wireless network using key authentication based secured multicasting technique

Multicasting is one of the fast and simple ways of transmitting a same data to multiple people at the same time in the network which saves the transmission time. Since multicasting is taking part of transmitting to multiple people there are chances for creating vulnerability against various attacks. In the existing system, MKMP - Multicast Key Management protocol is used in which the session information about the users is given to the sub stations for various groups. It is difficult to understand the user list under the sub stations, and there are chances to miss or mismatch the user list with the station information. To overcome this problem, in this paper KABSM-[Key Authentication based Secured Multicasting] approach is introduced and it provides a citizenship key for activating every functionality of the nodes in the network like, entering into a region, while communication etc. In this approach a dynamic key is generated and assigned to entire nodes in the network. The simulation result shows that the efficiency of the proposed approach is more sleuth to the existing approach.
