一种基于区块链的物联网行为监控和活动管理方案

A Blockchain-based Behavior Regulation and Activities Management Scheme for Internet of Things

作为新一代信息技术的典型代表,物联网的价值和意义已经得到世界各国的普遍认可。同时,物联网正面临着严峻的可扩展性和安全性挑战。文章以提升物联网安全性为研究目的,以物联网和区块链为研究对象,给出了物联网的六域模型,研究了区块链的数据格式,分析了物联网面临的安全威胁,解释了物联网和区块链融合框架,阐述了基于区块链的物联网安全解决思路。文章设计了物联网行为监控详细工作流程、基于定价机制的资源分配算法和基于信用系统的活动管理方案,并通过大量实验来评估方案的性能。结果表明,在充分发挥区块链和智能合约安全优势的同时,将区块链和智能合约集成到物联网安全方案中的成本在合理且可接受的范围内。

As a typical representative of the new generation of information technology,the value and significance of Internet of things(IoT)has been widely recognized by the countries all over the world.At the same time,IoT is facing serious scalability and security challenges.For the purpose of improving the security of the IoT,this paper takes IoT and blockchain as the research object,presents the six-domain model of IoT,studies the data format of blockchain,analyzes the security threats faced by IoT,explains the integration framework of IoT and blockchain,and elaborates the IoT security solutions based on the blockchain.This paper designs the detailed IoT behavior regulation workflow,pricing-based resource allocation algorithm and credit-based behavior management system,and conducts extensive experiments to evaluate the proposed scheme.The results show that while gaining the security benefits of blockchain and smart contracts,the cost of integrating them into IoT security scheme is within a reasonable and acceptable range.
