1. A method operative in an overlay network configured to provide UDP-based packet transport across the publicly-routed Internet between and among regions of co-located machines, the regions comprising at least one ingress edge region, and at least one egress gateway region, comprising:
organizing multiple regions of co-located machines into a collective, the collective associated with a trust level of a multi-level trust scheme;
having each of the machines in the multiple regions of the collective subscribe to a collection of keying materials, the collection being associated with the trust level of the collective, as well as one or more other trust levels lower in the multi-level trust scheme;
having a pair of regions of co-located machines use the keying materials to generate a key;
using the key to generate a message authentication code unique to the region pair; and
applying the message authentication code to data packets within a flow across the region pair to prevent attack.
