Dynamic Security Scheme for Multicast Source Authentication

Multicast source authentication is a burning issues in multicast communication because multicast technology provide the better communication than unicast and broadcast. But its design architecture any member can send the data to all joined receivers due to publicly available IP address of group manager. To solve this hottest problems, several schemes have been existed in this category such as simple hash chaining, tree hash chaining where the attacker intensity are unchanged. In this paper, we are going to propose a improved mechanism for multicast source authentication which adapts the security level deployed based on threshold value of attack success rate. The results shows that propose approach dynamic security mechanism in multicast at minimum communication and computation overhead (C) 2011 Published by Elsevier Ltd.
