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(yīng)用技術(shù)中,如區(qū)塊鏈,、物聯(lián)網(wǎng),、云計算等,在不需要中心節(jié)點的情況下,,為這些技術(shù)的實現(xiàn)提供了一種確保整個網(wǎng)絡(luò)中數(shù)據(jù)的完整性和一致性的手段,,是構(gòu)建大型分布式系統(tǒng)的重要技術(shù)方法,。共識算法的核心在于共識網(wǎng)絡(luò)中的節(jié)點參與投票過程,通過統(tǒng)計投票多寡決定節(jié)點行為,,最終達(dá)成一致狀態(tài)轉(zhuǎn)化,。
在共識執(zhí)行過程中,只要維持良性節(jié)點的占比不低于限定閾值,,就能夠保障系統(tǒng)安全[1],。共識算法的設(shè)計中沒有考慮針對惡意節(jié)點的懲罰機(jī)制,,而實際的分布式網(wǎng)絡(luò)環(huán)境中,,節(jié)點隨時存在受到攻擊轉(zhuǎn)為惡意的可能,原有設(shè)計缺乏對網(wǎng)絡(luò)韌性的考量,。
