Secure Data Aggregation Techniques in Smart Grid

Security is very important issues in data aggregation technique in smart grid systems. For efficient communication in smart grid systems network topology is also important factor. A home area network is basic data reading unit in smart grid. To achieve efficient communication in smart grid systems, appropriate network topology need to be selected. There is challenge in data aggregation because we have to make data aggregation secure without disclosing information during aggregation process and also obtain secure aggregated results. We described various protocols for data aggregation to be performed secured and network topologies in smart grid systems.
