A name resolving system services as the entrance to the IoT data, thus protecting the name resolving process and making it straight and simple are critical for the widespread application of IoT services. However, due to the centralized name management structure of the existing IoT name resolving systems, it is hard to secure the name resolving process from being tampered by the root owner of the name resolving system; due to the diversity and heterogeneous of the existing name resolving systems, it is hard to provide an unified name resolving service because the existing name resolving systems can hardly be compatible with each other. Herein, it is necessary to construct a general entrance to the existing IoT name resolving systems, and ensure that no IoT name could be malicious tampered.

In this paper, we propose the IoT-RU, a decentralized name resolving system for IoT. To persuade the IoT data service providers to participate in our IoT-RU, we construct its name resolving database on the blockchain ledger. To enable the adoption of the existing IoT naming schemes, IoT-RU integrates various name resolving schemes to resolve the IoT service providers in our system, and leave the job of locating individual IoT devices to the IoT service providers. We further investigate the feasibility of name management and resolving based on the current blockchain architectures. Based on the Ethereum platform, we construct a prototype of our name resolving system, and the corresponding evaluation indicates that our name resolving system manages to provide acceptable and scalable name resolution services.

名称解析系统用作IoT数据的入口，因此，保护​​名称解析过程并使其简单明了对于IoT服务的广泛应用至关重要。然而，由于现有物联网名称解析系统的集中式名称管理结构，难以确保名称解析过程不会受到名称解析系统的根所有者的篡改；由于现有名称解析系统的多样性和异构性，因此难以提供统一的名称解析服务，因为现有名称解析系统很难相互兼容。在此，有必要构建对现有物联网名称解析系统的通用入口，并确保任何物联网名称都不会被恶意篡改。

在本文中，我们提出了IoT-RU，一种用于IoT的分散式名称解析系统。为了说服IoT数据服务提供商参与我们的Io​​T-RU，我们在区块链分类账上构建其名称解析数据库。为了能够采用现有的IoT命名方案，IoT-RU集成了各种名称解析方案，以在我们的系统中解析IoT服务提供商，而无需将单个IoT设备定位到IoT服务提供商。我们将进一步研究基于当前区块链架构进行名称管理和解析的可行性。基于以太坊平台，我们构建了名称解析系统的原型，相应的评估表明我们的名称解析系统设法提供了可接受的可扩展名称解析服务。
