Secure communication apparatus and method for securing SCADA communication network

摘要

Disclosed are a secure communication apparatus and method for securing a SCADA (Supervisory Control And Data Acquisition) communication network. According to an embodiment of the present invention, a secure communication device for securing a SCADA communication network between a master and an outstation that is a subnode of the master may include a distributed network protocol (DNP) control command or a DNP from the master or the outstation. A first data receiver configured to receive DNP data including a response; An offensive mode component configured to generate secure DNP data by applying an offensive mode that attaches DNP message authentication data corresponding to a DNP standard security policy to the DNP data; And a first data transmitter for transmitting the DNP data or the secure DNP data to another secure communication device.
