摘　　要：针对分布式环境下节点动态移动导致跨信任域之间的信任转移以及信任阈值设置具有高度不确定性的问题,提出一种分布式环境下的跨信任域内的信任管理策略,该策略通过建立一种跨信任域的信任转移框架,利用源数据分布和重构后目标数据的信任差异来执行跨信任域之间的信任转移;在此基础上,基于新的信任域所有节点的信任分布自适应生成动态的信任阈值,从而实现恶意节点的准确识别。实验表明,所提出的方法有效解决分布式环境中跨信任域节点的信任管理问题,能够保障系统的整体信任质量和安全性。For the problem of trust transfer between cross-trust domains and high uncertainty in trust threshold settings caused by dynamic node movement in a distributed environment, a trust management strategy is proposed within cross-trust domains in a distributed environment. This strategy establishes a trust transfer framework for cross-domains via utilizing the trust differences between source data distribution and reconstructed target data to perform trust transfer between cross trust domains. On this basis, based on the trust distribution of all nodes in the new trust domain, the trust distribution of all nodes based on the new trust domain adaptively generates dynamic trust thresholds to achieve accurate identification of malicious nodes. The experiments show that the proposed method effectively solves the trust management problem of cross-trust domain nodes in distributed environments, which can ensure the overall trust quality and security of the system.
