报告内容摘要： 

Envisioned as the next-generation approach for large-scale electricity delivery and management system, the smart grid has introduced computation and communication capabilities into traditional power grids to make them "smart" and "connected". Through the Advanced Metering Infrastructure (AMI), smart meters communicate with electrical appliances at households and the control centers at the utility companies to achieve smart power generation, distribution, pricing, and other advanced management functions. With all the advantages introduced by smart grids, security and privacy naturally become one of the critical concerns that people may have about the smart system. 

In this talk, I will introduce two projects on security and privacy protection on the household and neighborhood side of the smart grid system. First, I will present a data aggregation approach to securely and efficiently collect aggregated information from distributed smart meters in the wireless mesh based neighborhood area network (NAN). Homomorphic cryptosystems are employed to enable privacy-preserving in-network operations, which provide better efficiency and scalability without sacrificing security. Next, I will introduce S2A, a security protection solution for smart devices. S2A employs machine learning technologies to provide smart and flexible protection for smart household appliances. It integrates device security, usability and pricing factors to generate an optimal operational strategy, which ensures appliances security while providing good usability and economic efficiency.
