摘　　要：由于在区块链系统中,随着各种设备的不断接入,会产生信息安全隐患,本文根据物联网存在的安全漏洞问题,结合区块链技术,设计了一种分布式的物联网信息安全管理系统,该系统可通过身份认证策略进行设备接入,对各种设备进行权限控制,同时在智能合约中融入安全仲裁机制,在信息管理方面,以数据进行分类存储,从而确保了数据的安全性。最后对系统各功能的测试,检测系统的安全性和有效性,通过对系统输入各类相关的信息数据,检验系统的输入结果,均达到了预期的目的。Security problems occur when multiple different devices are continuously connected with blockchain system.Aiming at these security problems in Internet of Things(IoT),this paper proposes to design a distributed IoT information security management system based on blockchain technology.This system can access devices through identity authentication and it will control the permissions of various devices.At the same time,security arbitration mechanism is integrated into a smart contract.In terms of information management,data is classified and stored in order to ensure data security.Finally,function test is conducted to test the safety and effectiveness.Various related data is used as system input and the system output results reach the expected goals.
