In this work we identify vulnerabilities of on- demand multicast routing protocols for multi-hop wireless networks and discuss the challenges encountered in designing mechanisms to defend against them- We propose BSMR, a novel secure multicast routing protocol that withstands insider attacks from colluding adversaries. Our protocol is a software-based solution and does not require additional or specialized hardware. We present simulation results which demonstrate that BSMR effectively mitigates the identified attacks.
