Summary:The invention relates to a satellite-ground cooperative data secure transmission method, and belongs to the technical field of secure communication. The method comprises the following steps: a service station firstly obtains an electromagnetic environment around a ground terminal, marks characteristic parameters of each electromagnetic signal, and calculates the carrier fitness of each electromagnetic signal according to the characteristic parameters; then the satellite divides information to be sent according to priorities; and finally, matching the to-be-sent information with different priorities with electromagnetic signals with different carrier fitness to complete information transmission. According to the satellite-ground collaborative data secure transmission method, through hidden transmission based on information priority division, the detectability of satellite-ground link communication is reduced, the robustness of hidden transmission is improved, and a solution thought is provided for improving th
