A packet forwarding process, on a data communications device, forwards a packet to a plurality of destinations within a network from that data communications device using an 'encrypt then replicate' method. The packet forwarding process receives a packet that is to be transmitted to the plurality of destinations, and applies a security association to the packet using security information shared between the data communications device, and the plurality of destinations, to create a secured packet. The secured packet contains a header that has a source address and a destination address. The source address is inserted into the header, and then the packet forwarding process replicates the secured packet, once for each of the plurality of destinations. After replication, the destination address is inserted into the header, and the packet forwarding process transmits each replicated secured packet to each of the plurality of destinations authorized to maintain the security association.
