Abstract: Because most of the existing networks adopt passive defense, which can not effectively resist malicious attacks by hackers in complex environments, an active defense model for complex network security under trusted cloud computing is established. After analyzing the importance of the attacked target and the harm caused by the attack, the attack strategy and defense strategy are classified. By initializing the defense map and judging whether it is 0, and analyzing that the attack and defense game model meets the conditions, the corresponding attack and defense cost is calculated according to the different analysis results. By judging the target and intention of each attack, the corresponding optimal defense strategy is formulated for the defense map. By carrying out simulation experiments and building network topology examples, the results verify that the proposed model can determine the optimal active defense strategy according to the attack target and attack path to ensure the security of network information. It is of great value for information security in a autonomous domain.
