A first plurality (201) of network nodes (120 - 123, 130 - 133) of a network (100) is associated with a first cryptographic keying material and the multicast IP address. A second plurality (202) of network nodes (120 - 123, 130 - 133) of the network (100) is associated with a second cryptographic keying material and the multicast IP address. The first cryptographic keying material has a different secret than the second cryptographic keying material. |
