CT-ISG: Collaborative Research: DNS Security Revisited: Enabling Cryptographic Defenses in Large-Scale Distributed Systems

题目：CT-ISG合作研究：DNS安全重述：在大规模分布式系统中启用加密防御spi: Lixia Zhang (UCLA), Songwu Lu （UCLA）和Dan Massey （Colorado State）域名系统（DNS）是一个核心的互联网协议，几乎所有的互联网应用都依赖于某种形式的DNS数据。该项目旨在确定并解决在全球互联网中部署DNS安全扩展（DNSSEC）的基本技术挑战。DNSSEC旨在通过应用定义良好的加密解决方案，通过数据源认证和数据完整性检查来增强DNS，但是在将加密解决方案转移到实际部署的过程中出现了许多系统问题。该项目首先对DNSSEC规范和部署约束之间的差距进行系统评估。对于每个确定的技术挑战，项目提出、实现和评估具体的解决方案，然后将这些解决方案集成到统一的设计改进中。部署DNSSEC对于增强网络空间的安全性至关重要，这一努力将通过克服现有障碍、预见道路上的新障碍以及开发清除这些障碍的使能技术，帮助推动DNSSEC向前发展。该项目还将推断出一组关于在大规模系统中部署加密保护的主要挑战的经验教训和原则，这将有望为其他加密部署工作（例如全球路由系统）提供输入。

Proposal: 0524854Title: CT-ISG Collaborative Research: DNS Security Revisited: Enabling Cryptographic Defenses in Large-Scale Distributed SystemsPIs: Lixia Zhang (UCLA), Songwu Lu (UCLA), and Dan Massey (Colorado State)The Domain Name System (DNS) is a core Internet protocol and virtually all Internet applications rely on some form of DNS data. This project is identifying and addressing fundamental technical challenges in deploying the DNS Security Extensions (DNSSEC) in the global Internet. DNSSEC aims at enhancing DNS with data origin authentication and data integrity checking by applying well defined cryptographic solutions, however a number of system issues have arisen in the process of moving the cryptographic solution to real deployment. This project is first conducting a systematic assessment of the gap between the DNSSEC specification and the deployment constraints. For each identified technical challenge, the project is proposing, implementing, and evaluating specific solutions and then integrating such solutions into a unified design improvement.DNSSEC deployment is critical to enhanced security in cyberspace, and this effort will help move it forward by overcoming existing roadblocks, foreseeing new obstacles on the road, and developing enabling techniques to clear these obstacles. The project will also extrapolate a set of lessons and principles on major challenges in deploying cryptographic protection in large scale systems, which will hopefully provide input into other cryptographic deployment effort, such as the global routing system.
