Lightweight Key Management Scheme for Wireless Communication System of Distribution Network

Abstract

Key management is the key to ensuring the information security of the intelligent distribution network. Based on the analysis of the communication characteristics and key management requirements of the intelligent distribution network, this paper proposes a lightweight intelligent distribution network key management scheme DNKMS. According to the storage and computing capabilities of power distribution terminals, electronic distribution stations and power distribution master stations, task distribution is optimized, and the design idea of the scheme and the process of key generation, distribution, update, and destruction are described in detail. The analysis results show that the proposed scheme has less time overhead and higher efficiency, can reduce the communication and calculation load required in key management, and meet the security requirements of key management in smart distribution networks.
