Decision method for dynamic network transformation under full information conditions and system thereof

The invention belongs to the technical field of network safety and specifically relates to a decision method for dynamic network transformation under full information conditions and a system thereof.The decision method comprises the following steps: obtaining state transition probability according to the network state, an attack strategy and a defense strategy; using a game theory to describe gains of both sides of the offensive and defensive game during moving target defense; constructing a moving target defense model based on a Markov game in combination with the state transition probability; transforming the solution of the moving target defense model into an equivalent of a target function and obtaining an optimal moving target defense strategy. According to the method and the systemin the invention, the moving target defense model based on the Markov game is constructed according to the state transition probability and both the sides of the offensive and defensive game; furthermore, the optimal moving ta
