摘要:
针对物联网(IoT)数据共享过程中存在的安全漏洞和隐私泄露风险,提出一种基于区块链的物联网数据共享方案.采用数据的不可篡改、分布式存储、隐私保护、可追溯及访问控制,将消息队列遥测传输(MQTT)作为通信协议和中间件,并为其提供身份认证和主题权限管理.结合国产加密算法实现密钥交换、数据摘要和加密传输,通过区块链记录设备的行为,在提高可信度的同时提供追溯的能力,采用智能合约对数据和主题进行共享和管理,实现链上链下数据协同保障数据的一致性.通过系统原型实现与测试,结果表明:该方案能够确保物联网设备之间共享数据时的安全性和隐私性,满足物联网应用性能需求,具有可行性.
Abstract:
Aiming at the security vulnerabilities and privacy leakage risks in the process of internet of things(IoT)data sharing, a data sharing scheme for IoT based on blockchain is proposed. The blockchain is used to realize data tamper-proof, distributed storage, privacy protection, traceability and access control. The message queue telemetry transport(MQTT)is used as a communication protocol and middleware, and provides identity authentication and topic permission management for it. The key exchange, data synopses and encrypted transmission are realized by combining the domestic encryption algorithm. The behavior of the device is recorded through the blockchain, and the traceability is provided while improving the credibility. The smart contract is used to share and manage the data and topics, and the on-chain and off-chain data coordination is achieved to ensure the consistency of the data. Through the system prototype implementation and testing, the results show that the scheme can ensure the security and privacy of data sharing between IoT devices, and meet the performance requirements of IoT applications, which is feasible.
