摘要
部分物联网预警方法由于未使用区块链技术,存在预警准确率较低,误警率较高的问题,因此提出了基于区块链技术的物联网风险预警方法。运用相同信道多个节点为网络信息签名,保证网络信息的正确性,运用网络信息区块链式存储结构获得正确的网络信息区块链账本;通过正确的网络信息区块链账本构建评估体系的网络分析结构,再使用网络分析法获得权重矩阵;利用灰色模型确认单因素模糊评价矩阵;将权重矩阵与单因素模糊评价矩阵相乘得到物联网风险预警的模糊综合评价矩阵,按照评估等级确定物联网风险预警等级。经验证,该方法能够准确预警物联网风险等级,存储网络信息和追溯信息的资源花销与时间消费较小,风险预警准确性较高误警率较低。
Due to the lack of blockchain technology,some Internet of things early warning methods have low accuracy and high false alarm rate.Therefore,studies the risk early warning method of Internet of things based on blockchain technology.Using multiple nodes of the same channel to sign the network information to ensure the correctness of the network information,using the network information block chain storage structure to obtain the correct network information blockchain account book;building the network analysis structure of the evaluation system through the correct network information blockchain account book,and then using the network analysis method to obtain the weight matrix;using the gray model to confirm the single factor fuzzy evaluation.The weight matrix is multiplied by the single factor fuzzy evaluation matrix to get the fuzzy comprehensive evaluation matrix of Internet of things risk early warning,and the risk early warning level of Internet of things is determined according to the evaluation level.After verification,the method can accurately warn the risk level of the Internet of things,the resource cost and time consumption of storing network information and traceability information are small,the accuracy of risk early warning is high,and the false alarm rate is low.
