Analysis and Research on Data Aggregation Scheme in Smart Grid
摘要
Abstract
The secure communication architecture in the smart grid is the basis for ensuring the security and stable opera-tion of the power grid. Privacy protection data aggregation is an effective way to ensure confidentiality and to improve effi-ciency. This paper summarizes and analyzes the five functional types of data aggregation schemes that have recently been geared toward smart grid communication systems. In the aggregation phase, most of the solutions are basically the same in terms of system architecture, but they have different considerations in the selection of aggregation methods. For exam-ple, Paillier encryption system and ElGamal encryption system are two kinds of more conventional encryption systems. Differential privacy, bilinear pairing technology and data signature technology are also applied in some articles. The secu-rity analysis proves that these solutions not only have the functions of privacy protection, message authentication, and integrity verification; but also through the comparative analysis of the performance of these solutions, the above-mentioned solutions are in terms of computational overhead and user access control and communication overhead. Each has its own advantages and provides more reference for the collection of multi-dimensional data in the smart grid and cloud access control.关键词
