Cyber security infrastructure of smart grid communication system

Solve the power communications network security issues, so that from malicious attacks. Through the establishment of electric power communications system dynamic security model for the whole network, the introduction of quantum cryptography communications technologies, building electric power communications system network security protection systems and communications network security framework system, and access to services on the smart grid of electric power communications network security technology system. And defence of the communications network to avoid controllability attacks (namely, illegal use), confidentiality attacks (namely, the secret to detect) and availability attacks (namely, vandalism). Support the smart grid of the power generation, transmission, substations, distribution, customer service, power dispatch, six links, and information platform for normal operation. Based on traditional cryptography communications technology, whole network dynamic security model of electric power communications system was established, quantum cryptography communications technology was introduced. Those are unique keys for cyber security infrastructure of smart grid communications system.
