In smart grid, control center collects and aggregates users' electricity data via the smart meters. The aggregated data is also of great use for markets. To efficiently and securely distribute these data to markets, the existing schemes use Attribute-based Encryption (ABE) technique to achieve privacy preservation of sensitive data and fine-grained access control. However, the efficient attribute...
Smart grid has recently emerged as the next generation of power grid due to its distinguished features, such as distributed energy control, robust to load fluctuations, and close user-grid interactions. As a vital component of smart grid, demand response can maintain supply-demand balance and reduce users' electricity bills. Furthermore, it is also critical to preserve user privacy and cyber security...
With the deployment of smart meters at individual households, smart grid can collect metering data of users' power consumption. However, users' power usage patterns would also be revealed. To preserve the users' privacy, metering data is mostly encrypted by cryptographic algorithms. When data mining is needed to support decision making or ensure reliability, to find useful information from the encrypted...
