Smart Grid Safe Interactive Strategy Cooperation

With the continuous development of smart grid technology, the smart grid is moving toward the direction of ubiquitous integration, thus the heterogeneous network elements have different security access techniques. The core of the smart grid information Safe interactive Strategy switch lies in network terminal information awareness, the underlying data of the cooperation decision support. This paper proposes a novel security cooperation framework based on network collaborative, to design a security policy switch decision method. The vertical cooperation security management module can effectively reduce the time delay and energy consumption of information gathering phase of the framework, providing powerful data support for the switching decision method.
