Abstract: A lightweight framework of Internet of Things (IoT) information sharing security based on blockchain technology was proposed to solve the problems of IoT's information sharing, such as source data susceptible to tampering, lack of credit guarantee mechanism and islands of information. The framework used double-chain pattern including data blockchain and transaction blockchain. Distributed storage and tamper-proof were realized on the data blockchain, and the registration efficiency was improved through a modified Practical Byzantine Fault Tolerance (PBFT). Resource and data transactions were realized on the transaction blockchain, the transaction efficiency was improved and privacy protection was realized through the improved algorithm based on partial blind signature algorithm. The simulation experiments were carried out to analyse, test and verify anti-attack capability, double-chain processing capacity and time delay. Simulation results show that the proposed framework has security, effectiveness and feasibility, which can be applied to most situations of the real IoT.

摘要: 针对物联网(IoT)信息共享中存在的源数据易被篡改、缺乏信用保障机制以及信息孤岛问题,提出一种基于区块链技术的轻量级物联网信息共享安全框架。该框架采用数据区块链和交易区块链相结合的双链模式:在数据区块链中实现数据的分布式存储和防篡改,并通过改进的实用拜占庭容错(PBFT)机制共识算法,提升数据登记效率;在交易区块链中实现资源和数据交易,并通过基于部分盲签名算法的改进算法,提升交易效率、实现隐私保护。仿真实验部分分别针对抗攻击能力、双链的处理能力和时延进行了验证分析,结果表明该框架具有安全性、有效性和可行性,可应对现实物联网中的大部分场景。
