The invention provides a game-based CPPS optimal resource allocation method for FDI attacks, which comprises the following steps of: firstly, obtaining a state estimation result of a system under a normal condition, then simulating a state estimation result after the FDI attacks, and taking an offset between the state estimation result and the state estimation result as the income of participants. And inputting the corresponding income amount, the resources required by the attacker to initiate the attack and the resources required by the defender to provide defense into the game model, calculating Nash equilibrium and obtaining the corresponding strategy and expected income, and finally, carrying out resource configuration on multiple nodes under the condition of limited resources. According to the distribution method, from the perspective of defenders, the defense efficiency is improved on the basis of ensuring the security of the system, and feasible suggestions and references are provided for the defenders
