Abstract:

In Ship Ad Hoc Networks, the dynamic topology and the frequent access and departure in the open environment make the trusted interaction between nodes a key issue. Traditional trust evaluation models often overlook network dynamics and the comprehensive mining of behavioral and historical data, leading to insufficient evaluation accuracy. To address this, this paper proposes a comprehensive trust evaluation model for access devices in Ship Ad Hoc Networks under a Zero Trust architecture. The model integrates direct trust based on behavioral evidence and indirect trust based on historical interactions. In direct trust evaluation, the fuzzy analytic hierarchy process and an improved artificial bee colony algorithm-optimized random forest model are combined to calculate subjective and objective weights, respectively, with optimal weight allocation achieved through the distance function method. Meanwhile, indirect trust evaluation enhances the weight of recent data and improves the timeliness and credibility of evaluation results by designing a time window mechanism and introducing a time decay factor. Experimental results demonstrate that the proposed model effectively improves trust evaluation accuracy. Additionally, it outperforms existing methods in terms of accuracy and detection rate under different malicious device proportions, significantly enhancing the dynamic adaptability and reliability of trust evaluation.

Keywords – Ship Ad Hoc Networks, access devices, Zero Trust, Random Forest, trust evaluation.
