Abstract

Abstract:

The security of user power consumption data is a problem that needs to be solved in the implementation of smart grid. For the security requirements of high-frequency data and low-frequency data are different in the smart meters, this paper proposes a privacy protection method for power users based on virtual ring architecture. First, using the NTRU encryption system to encrypt the user request data, then constructing the transmission paths of high-frequency data and low-frequency data. Low-frequency data is transmitted outside the ring. High-frequency data is anonymized in the ring, and user requests are aggregated with dynamic transaction token (DTT) . The privacy protection method guarantees the validity of grid operation and bill calculation, realizes the integrity of privacy protection of user power consumption data ,and improves the communication efficiency.

Key words: high frequency data, low frequency data, virtual ring architecture, dynamic transaction token, privacy
