摘　　要：随着卫星互联网在通信与组网方面的快速发展,跨域异构卫星相互建立链路并提供多样化数据服务,给卫星互联网安全带来了信任评估不准与卫星跨域不互信的挑战,因此,构建信任体系对卫星进行信任评估显得尤为重要。针对如何基于跨域网联态势与多维度信任观点动态评估卫星可信度,提出了一项基于跨域网联态势的多星座信任管理方案。该方案针对多星座场景,考虑多维度信任观点,设计分位图信任过滤机制,利用权重和方法聚合信任观点与信任阈值,最终判别卫星的可信度。实验结果表明,该方案的准确率、精确率、召回率与F值均优于其他基准算法。With the rapid development of communication and networking technologies in satellite networks,cross-domain heterogenous satellites establish connectivity with each other and provide various data services,which bring serious challenges to satellite networks,such as inaccurate trust evaluation and cross-domain mistrust of satellites.Therefore,it is particularly important to build a trust system to evaluate trust of satellites.To evaluate the trustworthiness of satellites based on cross-domain network situation and multi-dimensional trust opinions,a cross-domain network situation-based trust management in multiple constellations was proposed.The multi-dimensional trust opinions in multiple constellations was considered,and quantile-quantile plot trust filtering mechanism was designed.Then,trust opinions and trust thresholds were weighted to identify the trustworthiness of satellites.Experiment results show that the proposed method outperforms baselines in terms of accuracy,precision,recall,and F-value.
