Privacy-Preserving and Traceable Data Aggregation in Energy Internet

Abstract

Energy Internet is considered as a promising approach to solve the problems of energy crisis and carbon emission. It needs to collect user’s real-time data for optimizing the energy utilization. Edge nodes like GWs (gateway) are used for data aggregation to improve the efficiency of the system. Due to a large number of GWs are widely distributed and difficult to be managed, which brings potential security threats for the Energy Internet. Existing data aggregation schemes fails in preventing the adversary from controlling or destroying GWs. In this paper, we propose an IBE-based Device Traceable Privacy-Preserving Aggregation Scheme, named IBE-DTPPA. Increasing the RA (Residential Area) users’ data aggregation integrity verification by BGN Cryptosystem; using IBE Cryptosystem to encrypt aggregation data, calculating ciphertext based on GW’s dynamic ID, realizing the target GW traceability; choosing CC (Control Center) dynamic identity information as public key to realize CC authentication, preventing adversary from using CC’s identity fraudulently. Through extensive analysis, we demonstrate that IBE-DTPPA resists various security threats, and can trace target GW efficiently.
