作为DNS隐私的一种有前途的解决方案，查询名称最小化限制了DNS请求中查询名称信息的不必要泄漏。由于缺乏详细的度量研究，人们对查询名称最小化的性能、兼容性和安全性影响了解甚少。在本文中，我们衡量查询名称最小化的性能。我们发现，查询名称最小化需要一个显着的查询增加，但NXDOMAIN优化技术可以减轻增加。我们提出了一个查询名称最小化的DDoS漏洞，并使用NXDOMAIN优化评估其影响和防御。破碎的空非终端测量和确定的关键障碍，过渡到查询名称最小化。
As a promising solution to DNS privacy, query name minimization limits the unnecessary leakage of query name information in DNS requests. Due to the lack of detailed measurement study, there is little understanding of the performance, compatibility, and security implications of query name minimization. In this paper, we measure the performance of query name minimization. We find that query name minimization requires a significant query increase but NXDOMAIN optimization technique can alleviate the increase. We propose a DDoS vulnerability with query name minimization and evaluate its impacts and defenses using NXDOMAIN optimization. Broken empty non-terminals are measured and identified as the critical obstacles to the transition to query name minimization.
