区块链技术在软件定义物联网安全中的应用探析

Analysis of the Application of Blockchain Technology in Software-Defined Internet of Things Security

软件定义物联网(Software Defined Internet of Things,SD-IoT)是一种基于软件定义网络(Software Defined Networking,SDN)的物联网架构,它通过SDN技术将物联网中的物理网络和控制平面进行分离,将网络控制平面交给SDN控制器进行统一管理和控制,提供了更加灵活、可扩展和可管理的物联网服务。但是,由于软件定义物联网架构的灵活性和开放性,也为攻击者提供了更多的攻击机会,因此如何保证软件定义物联网系统的安全性是一个重要的研究方向。区块链技术作为一种分布式、去中心化、不可篡改的技术,可以为SD-IoT中的授权和管理提供更加安全和可靠的解决方案,在应对软件定义物联网应用授权、数据安全和防止恶意攻击等问题方面,具有独特的技术优势。

The software-defined Internet of Things(SD-IoT)is an Internet of Things architecture based on software-defined networking(SDN).It uses SDN technology to separate the physical network and control plane in the Internet of Things,and hands over the network control plane to the SDN controller for unified management and control,which provides more flexible,scalable and manageable Internet of Things services.However,the flexibility and openness of the SD-IoT architecture also provides attackers with more attack opportunities,so how to ensure the security of the SD-IoT system is an important research direction.Blockchain technology,as a distributed,decentralized and tamper-proofing technology,can provide more secure and reliable solutions for authorization and management in the SD-IoT,and it has unique technical advantages in addressing issues such as the application authorization,data security and anti-malicious attack of the SD-IoT.
