The air-based information network of the Space-Air-Ground Integrated Network has the distinct characteristics of heterogeneous, time-varying, distributed and self-organized, which bring not only new challenges of node mobility model, dynamic network grouping and interconnection and intercommunication of heterogeneous networks, but also higher requirements of network security. Therefore, selecting an efficient and safe communication link is critical when there may not be fixed rules. In this article, we build a model of the air-based information network, and use the method of dynamic programming to select the most efficient communication link by minimizing the energy consumption in the communication model. In the communication model, energy consumption is associated with the security level of the communication link. The experiments show that the presented algorithms can effectively reduce the total cost while satisfying security constraints.
