Protect power dispatch control system and its network information security

In substation automation, the current protocol used functions are not set to ensure that the control commands from the initiator is authorized, there is no effective measures to prevent the passage is likely to occur on the communication line circuit breaker operations such as forgery SCADA instruction terrorist threat. how to  air circuit breaker  the power dispatch control system and network information security, to achieve the important information or access control critical operations has become a very urgent task. research institutions at home and abroad on the power  mcb circuit breaker  security issues widely research, but the study focused on the power entry point for information systems security system and safety  Voltage stabilizer  on the issue, and for the substation automation system data exchange, system configuration access control problems exist, but has not put forward practical solutions.
