Application-Aware Secure Multicast for Power Grid Communications

This paper proposes 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. The authors designs an abstract multicast model, analysis algorithms, and configuration derivation techniques. These are implemented in a prototype system, SecureSCL. The authors also provide experimental evidence that IPsec multicast can address latency constraints in power substation networks.
