A Distribution Network Model Management Scheme with High Trusted Two-way Encryption Authentication

Abstract

The stolen or modified data transmission between the primary station and the terminal in the distribution network automation communication system will have a great impact on the security of the entire distribution network, and the large-scale distribution network encrypts the communication data between the primary station and the terminal. Efficiency puts higher demands. Based on the national network adjustment [2011] No. 168 document and the current distribution network security protection scheme, a high-reliability automated distribution network model management scheme based on two-way encryption authentication technology is proposed. Solve the problem that the uplink data of the terminal is not credible due to the single authentication between the primary station and the terminal in the current distribution network protection scheme. Compared with the current distribution network, the proposed scheme integrates the network layer and the application layer, unified key management, and implements a low-latency, highly trusted two-way encryption authentication mechanism for data transmission between the primary station and the terminal. It is the first in China.
