Mobile ad hoc networks (MANETs) play a significant role for communication whenever infrastructure is not available. In MANET, the group communication-based applications use the multicast routing protocol, where there is a single sender node and a group of receiver nodes. The benefits of multicast routing protocols are the capability to reduce the communication costs and saving the network resources by reproduction of the message over a shared network. The security is the main concern for multicast routing protocol in MANET, as it includes large number of participants. The security issues become more rigorous in a multicast communication due to its high variedness and routing difficulty. In this paper, we consider the internal attack, namely Multicast Announcement Packet Fabrication Attack on PUMA (Protocol for Unified Multicasting through Announcements). We proposed the security approach to detect the attacks as multicast activity-based overhearing technique, i.e., traffic analysis-based detection method with a unique key value. The performance analysis, shows an improved network performance of proposed approach over PUMA.
