Abstract

This paper focuses on edge terminals in distributed renewable energy systems and investigates lightweight secure computation to achieve secure, ef-ficient, and privacy-preserving data processing. To address the challenge of limited computing power in edge computing, the paper proposes a lightweight underlying Secure Multi-Party Computation (SMPC) architecture and designs basic computing components for encrypted data as well as an identity authentication mechanism for edge nodes. The paper further investigates encrypted-data perturbation aggregation technology and develops a cross-platform acceleration engine and dedicated operators. In addition, AI is used for three-phase unbalanced voltage analysis, and identity authentication and privacy protection schemes for service data are designed to realize data aggregation based on differential privacy. For homomorphic encryption and oblivious transfer protocols, a lightweight secure-computation optimization strategy is proposed. The research results are validated in actual power systems, providing support for secure computation on edge terminals.
