摘要
针对共识算法对良性节点占比的依赖,设计了一种基于信誉评分的共识网络重组机制,使得网络能在遭受攻击或发生故障时迅速自我修复和重组,显著提升了抗攻击能力和服务连续性。首先基于信誉机制理论,开发了一个分布式信誉评分系统,实时评估节点信誉,有效处理潜在恶意节点。此外,提出了一种基于信誉评分的共识网络重组机制,通过识别和隔离恶意节点来增强网络的弹性和安全性。该机制设计了网络弹性重组算法,整合了冗余设置、故障诊断和服务节点重新配置功能,确保网络稳定运行和高可靠性。该研究对金融服务、云计算和物联网等广泛使用共识技术的高安全需求领域具有重要应用价值。
In view of the dependence of the consensus algorithm on the proportion of benign nodes,a consensus network reorganization mechanism based on credit score is designed,so that the network can quickly repair and reorganize when it suffers from attack or failure,which significantly improves the anti-attack ability and service continuity.In this paper,a distributed credit scoring system based on the theory of credit mechanism is developed to evaluate the node reputation in real time and effectively deal with potential malicious nodes.Furthermore,a consensus network reorganization mechanism based on credibility scoring is proposed to enhance the network resilience and security by identifying and isolating malicious nodes.This mechanism designs the network elastic reorganization algorithm,which integrates the redundant setting,fault diagnosis and service node reconfiguration functions to ensure the stable operation of the network and high reliability.This research has important application value in high security needs areas such as financial services,cloud computing and Internet of Things where consensus technologies are widely used.
