摘要
传统物联网设备管理系统可能存在隐私数据易泄露、设备运行情况难掌握、异常事件难追溯等痛点,给个人、企业乃至社会层面都带来了不利影响.针对以上问题,本文设计了一种基于区块链的物联网设备自主管控及管控行为审计方案,通过区块链存证技术将接入系统的设备信息锚定至区块链,对设备全生命周期进行管理;基于智能合约技术实现对物联网设备的数据采集、分析及远程管控的一体化自主管控流程;最后,结合区块链不可篡改和可追溯的特性对用户行为进行安全审计.分析结果表明,本方案具备安全性高、扩展性强等特点,为构建物联网系统安全管理架构提供了思路.
The traditional IoT device management system may have drawbacks such as easy leakage of privacy data and difficulty in grasping the device operation conditions and tracing abnormal events,which poses adverse effects on individuals,enterprises,and even society.Given these problems,the study proposed a blockchain-based IoT device autonomous control and behavior audit scheme.Through blockchain deposition technology,the device information connected to the system is anchored to the blockchain to manage the whole life cycle of the device.Moreover,based on smart contract technology,the integrated autonomous control process including data collection,analysis,and remote control of IoT devices is realized.Finally,the scheme explores the untamperable and traceable features of blockchain to audit the users’behavior.The analysis results show that the proposed scheme has high security and strong scalability,which has the ability to build a security management architecture for the IoT systems.
