Abstract: In connection with problems such as difficulty in the objective and accurate calculation of the index weight in the security risk assessment of an airborne network, as well as a unitary assessment result and poor descriptiveness, a risk assessment method for airborne network security based on an improved fuzzy analytic hierarchy process (FAHP)-cloud model has been proposed. First, the particularity of the airborne network is taken into account to establish an index system for the risk assessment of airborne network security. the traditional FAHP, information entropy is introduced to calculate the comprehensive weight, which is subsequently combined with the cloud model theory to construct an actual integrated cloud model. By calculating the degree of similarity between the actual integrated cloud model and the standard cloud model, the risk levels of airborne network security are determined. The simulation experiments show that this method can reflect the objectivity of the index weight, make the assessment results more visual and reliable, and fully reflect the fuzziness and randomness in the assessment.
