%X A Mobile Ad hoc NETwork (MANETs) is a continuously changing wireless network that can be created without any pre-existing infrastructure in which each node can operate as a router. MANETs has no clear line of control, so it is accessible to both legitimate network users and malicious attackers. The main challenge in MANETs is to design a secure solution which can protect the MANET from various kinds of security attacks.In this paper, we put a first step towards securing multicast routing protocol for ad hoc network. Specifically we examine the vulnerabilities of PUMA (Protocol for Unified Multicasting through Announcements) which is a representative of mesh based routing protocol. In this proposed work, we have presented a trust based approach where in which the secure route is selected for the receivers not only based on current trust values of its neighbor nodes but also its past experience is considered for blackhole and wormhole attack
