应用区块链解决物联网安全问题的初步调查

Preliminary Survey of Applying Blockchain to Solve IoT Security Issues

安全性仍然是2020年物联网开发人员最关心的问题,分布式账本已成为保护物联网解决方案的一种方式。区块链因其去中心化、不可篡改和可追溯性逐渐成为物联网安全问题的重要解决方案,但物联网设备因规模庞大、资源限制等无法满足区块链对计算和存储资源的需求。通过对致力于使用区块链解决物联网安全问题的部分国际论文进行初步调查,对他们所采用的技术、针对安全问题的设计,以及已解决的攻击是否有资源约束和可伸缩性考量等方面进行统计和分析。研究发现,目前区块链与物联网集成方面还有很大的研究空间,尤其是集成框架模式、区块链和共识机制的设计等,是决定区块链是否能够应用于大规模物联网实际应用场景的关键。

Security remains a top concern for IoT developers in 2020,and distributed ledgers have emerged as a way to secure IoT solutions.Blockchain has gradually become an important solution to IoT security problems because of its decentralization,immutability and traceability.However,IoT devices cannot meet the computing and storage resources demand of blockchain due to their large scale and resource constraints.This paper conducts a preliminary survey of some representative international papers devoted to the use of blockchain to solve IoT security problems,through the technology they employ,the design of the security problem,and the attacks they addressed,whether there are resource constraints and so on.It is found that there is still a lot of research space for the integration of blockchain and the IoT,especially the integration framework,the design of blockchain and consensus mechanism,etc.are the keys to whether it can be applied to large-scale IoT practical application scenarios.
