Erforschung neuer, sicherer und effizienter Protokolle zur Streckenplanung in offenen und heterogenen Netzwerken.

本文主要研究开放异构网络中安全高效路由协议的设计、分析、实现和部署。路由协议是互联网的基本组成部分，许多安全问题是由于现有路由算法和协议的局限性而产生的。具体来说，目前使用的Internet路由协议并不是为处理拜占庭式故障而设计的，而是需要可信的提供者来管理基础设施。可悲的是，网络提供商常常因为无能或恶意等问题而不被信任。现有的体系结构也使得难以构建替代的安全ad-hoc社区网络，迫使用户使用“可信的”互联网服务提供商（isp）来方便地访问网络。拟议工作的成功执行将使最终用户能够自由地参与完全分散的网络，而不需要受信任的各方。它还将提供现有互联网应用程序到这些网络的平滑集成或迁移，而且还将使一系列全新的应用程序成为可能。该项目的主要挑战是提供一个分散的、可扩展的解决方案，提供所需的安全属性，理想情况下还为运营商提供高质量的网络服务提供经济激励。所提出的设计对硬件没有特别的要求，并且旨在在有关对手参与网络操作的现实假设下运行。

The proposed research is about the design, analysis, implementation and deployment of new secure and efficient routing protocols for open and heterogeneous networks. Routing protocols are the fundamental building block of the Internet and many security problems arise from limitations in the existing routing algorithms and protocols. Specically, the Internet routing protocols that are currently used are not designed to handle byzantine failure and require trusted providers to manage the infrastructure. Sadly, network providers often cannot be trusted because of issues such as incompetence or malice. The existing architecture also makes it difficult to build alternative secure ad-hoc community networks, forcing users to use \trusted" Internet Service Providers (ISPs) for convenient network access. Successful execution of the proposed work will enable end-users to participate freely in fully decentralized networks without the need for trusted parties. It will also provide for smooth integration or migration of existing Internet applications to such networks, and will, moreover, enable a whole new range of applications. The main challenge of the project is to provide a decentralized, scalable solution that provides desired security properties and ideally also provides economic incentives for operators to provide quality network service. The proposed design imposes no unusual requirements on the hardware and is intented to operate under realistic assumptions about adversaries participating in the operation of the network.
