摘要
物联网技术在医疗、金融、智能城市建设等领域中有着重要应用,是各个行业的现代化建设必不可少的技术。但物联网的安全性较差,无法有效保护用户的隐私安全。研究利用区块链技术提升物联网的安全性与保密性,利用实用拜占庭容错共识算法提升物联网的容错性能,构建物联网信息安全系统。研究结果表明,该系统对异常节点的检测准确率超过了90%,证明物联网信息安全系统有较好的抗攻击性和容错能力,能够有效保护物联网用户的隐私安全,具有较高的实用性。
Internet of Things technology,which is an essential technology for the modernization of various industries,has important applications in medical,financial,intelligent city construction and other fields.However,the security of the Internet of Things is poor,which can not effectively protect the privacy and security of users.This paper studies the use of blockchain technology to improve the security and confidentiality of the Internet of Things,uses the Practical Byzantine Fault Tolerance consensus algorithm to improve the fault tolerance performance of the Internet of Things,and constructs the Internet of Things information security system based on the above methods.The results show that the detection accuracy of the system for abnormal nodes is more than 90%,which prove the Internet of Things information security system has good anti-attack and fault tolerance,can effectively protect the privacy and security of Internet of Things users,and has high practicability.
