Existing industrial control system, in order to increase the reliability of the data, and access control through the separation of external network. However, the current industrial control system tends to increase the efficiency of operations and systematic management, the need for connection to an external network in consideration of economic aspects have increased. These developments are to have vulnerabilities more security than in the past, communications in industrial control systems requires special control method.
In this paper, taking into account the domestic environment, it was presented the security authentication technology that was applied to serial DNP3 and TCP / IP-based DNP3, which is mainly used in the Control Center and the Field Device. Presented to security of Certification technology, divided into Resource Robustness Test and Malicious Packet Test for evaluate the safety. Each of the security requirements and evaluation method in proposed technology, is an attempt to present the differentiation of the existing Certification technology. And propose specific methods for Fuzzing tests in the security authentication technique to be proposed and implemented, by testing the actual domestic power control system equipment, and tried to verify compliance.
