A novel privacy preserving data aggregation scheme with data integrity and fault tolerance for smart grid communications

摘要

1 Introduction By making the best of the information technology in smart grid,considerable power energy can be effectively saved[1,2].However,frequently collecting userJs power consumption data incurs privacy disclosure issues.Meanwhile,data integrity is also critical to make the decisions to be more credible and reliable.And the smart meters for collecting electricity consumptions are prone to communication failures for being deployed in unattended environment commonly.
