Application-Aware Secure Multicast for Power Grid Communications

We propose an application-aware approach to setting up secure multicast groups for power grid communications that automatically derives group memberships and verifies configuration conformance from data dependencies in system specifications. We design an abstract multicast model, analysis algorithms, and configuration derivation techniques. These are implemented in a prototype system, SecureSCL. We also provide experimental evidence that IPsec multicast can address latency constraints in power substation networks.
