摘要:
域名系统(Domain Name System,DNS)的中心化根解析体系蕴含着权力滥用风险,对互联网的开放与平等形成威胁。本文提出了一个新的自主开放根解析体系,与现有DNS兼容的同时,从结构和机制两方面对权力滥用予以威慑。首先,针对域名唯一性与去中心化之间矛盾,提出了授权与解析分离机制,在保留单一根权威的条件下,实现解析服务去中心化。接着,针对中心式结构风险,提出建立国家根与根联盟,通过自治与合作实现权力制衡。然后,分析了新体系防范风险的有效性以及在当前DNS基础之上的增量,并讨论新体系所具有的自主、开放、平等、透明性质。最后,对新体系的安全性进行分析并给出了一个原型系统。

Abstract:
The current DNS (Domain Name System) root resolution architecture has the risk of power abuse which posts threats on the openness and equality of the Internet. This paper presents a new DNS-compatible autonomous open root resolution architecture to effectively prevent the power abuse from the perspectives of structure and mechanism. First, aiming at the dilemma between the name uniqueness and decentralization, we propose the separation of delegation and resolution to decentralize resolution service while keeping a single root authority. Then, to cope with the risk in the centralized structure, we propose a structure with country roots and inter-root to provide power balancing. We analyze the effectiveness of the new architecture against the abuse threats and the changes on current DNS. We discuss the autonomy, openness, equality and transparency of the new architecture. We also analyze the security of the new architecture and implement a prototype.
