摘要: 針對共識算法對良性節點占比的依賴,設計了一種基于信譽評分的共識網絡重組機制,使得網絡能在遭受攻擊或發生故障時迅速自我修復和重組,顯著提升了抗攻擊能力和服務連續性。首先基于信譽機制理論,開發了一個分布式信譽評分系統,實時評估節點信譽,有效處理潛在惡意節點。此外,提出了一種基于信譽評分的共識網絡重組機制,通過識別和隔離惡意節點來增強網絡的彈性和安全性。該機制設計了網絡彈性重組算法,整合了冗余設置、故障診斷和服務節點重新配置功能,確保網絡穩定運行和高可靠性。該研究對金融服務、云計算和物聯網等廣泛使用共識技術的高安全需求領域具有重要應用價值。

Abstract: 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 antiattack 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.
Key words : credit mechanism; distributed system; network restructuring
引言
共識算法被廣泛運用于各種最新的應用技術中,如區塊鏈、物聯網、云計算等,在不需要中心節點的情況下,為這些技術的實現提供了一種確保整個網絡中數據的完整性和一致性的手段,是構建大型分布式系統的重要技術方法。共識算法的核心在于共識網絡中的節點參與投票過程,通過統計投票多寡決定節點行為,最終達成一致狀態轉化。
在共識執行過程中,只要維持良性節點的占比不低于限定閾值,就能夠保障系統安全[1]。共識算法的設計中沒有考慮針對惡意節點的懲罰機制,而實際的分布式網絡環境中,節點隨時存在受到攻擊轉為惡意的可能,原有設計缺乏對網絡韌性的考量。
