Safe Multicast approach in Wireless MAN

Abstract —Multicast delivery of information is an intense component that has solid potential. The favourable effectiveness over unicast is a positive position, however the utilization of multicast postures numerous security dangers. Adequately adding efforts to establish safety to a multicast administration is a fascinating issue, particularly when the administration is conveyed in a remote setting. Next era IEEE 802.16 standard Wireless MAN systems are a flawless case of this issue, and the most recent draft particular of the standard incorporates a protected convention arrangement called Multicast and Broadcast Rekeying Calculation (MBRA). In this paper, we uncover the security issues of MBRA, including non-adaptability and exclusion of in reverse and forward secrecy, and propose a new approach, ELAPSE, to address these issues. We break down the security property of ELAPSE and utilization Qualnet recreations to demonstrate its productivity.
