Abstract:
A method is provided for securely transmitting multicast data across an unsecured public network. Such a method includes receiving a join message identifying at least one private multicast group; mapping the private multicast group to a public multicast group; generating a membership report specifying the public multicast group; and sending the membership report to the unsecured network. Additionally, the method may further comprise creating a secure tunnel through the unsecured network to a network element coupled; generating an encrypted control message specifying the private multicast group; and sending the encrypted control message through the secure tunnel to the network element.
