Abstract

Abstract:

A distribution automation system is mainly composed of a distribution master station,distribution substations and distribution terminals.The working status of the terminals and the master station will influence the stable operation of the whole system.In order to keep the communication security of the system,a communication system was built between the DTU （Data Transfer Unit） and the master station based on TCP protocol.DoS attacks were made to the system to verifies the existence of security threats.In order to enhance the anti-DoS attack capability of the communication system,a whitelist-based protection strategy is proposed.

Key words: DTU, distribution automation, DoS attack, whitelist, smart grid, intelligent terminal
