Secure, Scalable Information Infrastructure for Smart Grid (with Bell Labs)
|
[ Challenges ]
- Smart Grid applications are imposing challenging requirements of security and reliability on the N-way com- munication infrastructure being designed to support multiple grid applications. These challenges stem from the increasing incorporation of distributed renewable energy sources on to the grid, the rising deployment of electric vehicles, and active consumer participation into power grid operations, all of which communicate with the utility control center with varying degrees of priority and security.

[ Overview ]
- SeDAX: SEcure Data-centric Application eXtensible platform for Smart Grid applications
- The SeDAX architecture has as its basis a Delaunay Triangula- tion (DT) network. The properties of the DT graph are leveraged to scalably support secure data-centric (or information-centric) group communication. The primary goals of this platform are to support communication resilience and data availability. The key functional blocks of the SeDAX platform are: (1) a geographic hash forwarding algorithm that operates over the DT graph (DT-GHF), and (2) a DT-based data replication scheme. The forwarding and replication schemes are scalable and cost effective in terms of communication overhead and memory.
