Study of Software Security Based on SLDMRP Multicast Routing Protocol

To focus on the current problem from the multicast routing protocols that are only considered about them, and then rarely take the security needs of less common into account. It is an ideal state protocol that is established without any infrastructure communications. During the procedure of data transfer, it is extremely vulnerable to eavesdrop, swindle, tampering or replay (Relay) routing information security. Thus, the SLDMRP protocol that it based on security put forward in this paper. This protocol is designed on the basis of the multicast routing LDMRP, while this protocol creating and maintaining multicast group, sending control message, to carry out security policy that is underwritten and verified the data packets, in order to prevent the control message from eavesdropping and tampering. Finally, through simulation results show that its security strategy is effective.
