The Design of an Industrial Remote Control Network Gateway Based on P2P VPN

An industrial remote control network gateway was designed to study and solve the security problems generated by the network communication between SCADA system and industrial computers, and provide security guarantee for making industrial network connect with the Internet under the premise of full efficiency and reliability. It is not dependent on any hardware environment and SCADA software environment, and capable of supporting any industrial equipment and all kinds of SCADA system, the gateway can monitor industrial equipments of industrial sites, forward packets between SCADA system and industrial computers, and block untrusted data, it can report abnormal events to solve the problems of remote Internet network communication between SCADA system and industrial equipments and provide security communication mechanism.
