Problems solved by technology

[0002] The original distribution network terminal did not authenticate the received IEC101 protocol message, which made it easy to be used by illegal attackers, simulating the master station to send IEC101 protocol message to the terminal, and maliciously controlling it, destroying the distribution network normal operation of the system
As the country attaches great importance to the network security of industrial control systems, especially in the field of power automation systems, distribution network terminals gradually adopt IEC protocol message authentication technology, but there is no method that can help power grid information security supervision departments effectively To verify the validity of IEC101 protocol message authentication, and to identify distribution network terminals using IEC protocol message authentication is a key element in evaluating the information security of distribution automation

Embodiment Construction

[0018] First combine below figure 1 The system to which the present invention is applied will be described.

[0019] The applicable systems include SCADA servers, several advanced application servers, several historical data storage servers, several maintenance servers, and several dispatch servers. All of the above-mentioned servers are connected to the master switch except for the dispatch server to realize the connection with several FES servers. Each FES The server then connects to a vertical encryption device. The vertical encryption device is connected to a front-end data collection switch, and the front-end data collection switch is connected to each intelligent power distribution terminal through a vertical encryption device. Each dispatch server is connected to a forward and reverse isolation device with a firewall. The forward and reverse isolation device is connected to the information exchange area.

[0020] The above-mentioned smart power distribution terminal is th...

Abstract

The invention provides a power distribution network terminal IEC101 protocol message authentication judging method. According to the method, by establishing a simulation master station capable of sending messages, related testing messages are sent to a power distribution network terminal; and in corresponding modes of the power distribution network terminal, information safety of the power distribution network terminal is judged. According to the invention, whether the power distribution network terminal carries out authentication on an IEC101 protocol message can be rapidly judged; fussy manual testing checking on the IEC101 protocol message is avoided; information safety checking efficiency of a power distribution network automatic system is improved; and safety operation of the power automatic system is ensured.

Description

Technical field [0001] The present invention relates to the technical field of power distribution safety, in particular to a method for authenticating and discriminating IEC101 protocol messages of a power distribution network terminal. Background technique [0002] The original distribution network terminal did not authenticate the received IEC101 protocol message, which made it easy to be used by illegal attackers, and simulated the master station to deliver the IEC101 protocol message to the terminal, and carried out malicious control to damage the distribution network. The normal operation of the system. As the country attaches great importance to the network security of industrial control systems, especially in the field of power automation systems, the power distribution network terminals have gradually adopted the IEC protocol message authentication technology, but there is no method to help the power grid information security supervision department effectively Verifying ...
