Big Data Security Analytic for Smart Grid with Fog Nodes

Big data throws big security challenges in Smart Grid. Fog computing emerges as a novel technology to bring the ability of Cloud and big data analytic (BDA) to the edge of the networks. However, we lack practice on how to utilize Fog, Cloud, and BDA to address big data security challenges in Smart Grid. In this paper, we propose a Mapreduce-style algorithm, named Mapreduce-style Fast Non-Technical Loss Fraud Detection scheme (Mapreduce-style FNFD), to detect Non-Technical Loss fraud in Smart Grid. Compared to its original version, FNFD, Mapreduce-style FNFD can utilize the ability of Cloud, Fog, and BDA, and thus can solve big data security issues.
