基于区块链的分布式节点访问风险预警系统设计

Design of distributed node access risk early warning system based on block chain

针对传统风险防控预警系统访问时间长,预警准确率低的问题,基于区块链设计了一种新的分布式节点访问风险防控预警系统。通过两条线路负责控制节点工作,每条线路执行不同任务:第一条线路负责传输应用数据和系统数据;第二条线路负责传输入侵检测信息包。系统硬件由风险检测模块、任务分析模块、资源控制模块、中心协调模块和用户模块组成,以中心协调模块与控制模块作为枢纽确保系统连续运行。软件由发布任务、检测回复列表是否为空、检测是否存在风险、风险预估四步组成。为验证系统的有效性,设计对比实验,结果表明,给出的系统能够在短时间内更精准地访问风险,应用该系统可以更好地在金融领域实现风险防控预警。

A new distributed node access risk prevention&control early warning system is designed based on the block chain to cope with the long access time and low early warning accuracy of the traditional risk prevention&control early warning system.In the system,the work of the control node is achieved by two lines,each of which performs different tasks.The first line is used for transmitting application data and system data,while the second line is used for transmitting intrusion detection information packets.The system hardware is composed of risk detection module,task analysis module,resource control module,central coordination module and user module.The central coordination module and control module are taken as the hub to ensure the system′s continuous operation.The software functions consist of issuing tasks,checking whether reply list is empty,checking whether there are risks,and risk estimation.Contrastive experiments were designed to verify the system effectiveness.The results show that the proposed system can predict the access risk more accurately in a short time,and the application of the system can better realize the risk prevention&control early warning in the financial field.
