In response to the certain uncertainty,randomness,and fuzziness of existing risk assessment methods of airborne entertainment system,as well as the strong subjectivity of their evaluation indicators,which leads to inaccurate and non-objective evaluation results,this paper proposes a risk assessment method of airborne entertainment system based on multidimensional cloud model and entropy theory. Firstly,more comprehensive,fine-grained,and objec-tive system vulnerabilities are used as evaluation indicators,and based on this indicator data,a multidimensional cloud model graph is generated to visually display the membership degree of different risks. Then,the risk value of the entire core component is calculated based on the probability of security events occurring and the probability of security events losses. And compared with the risk comparison table,the risk assessment result of the entire system is obtained. Multiple experimental results have shown that the evaluation results of the proposed method in this pa-per have better stability,accuracy,and objectivity.
