The goal of the proposed work is to build a foundation for enabling a rich set of applications on entirely unstructured, decentralized, and distributed networks. Recently, a number of different research applications have been built on similar platforms in the context of peer-to-peer systems. While these research systems offer great promise, we believe significant work is required in order to build deployable applications over these systems. This work is motivated by the open issues in this area, and is organized into three major thrusts: (1) placement and lookup algorithms that are robust against a range of adversarial failure models, and yet - in contrast to, e.g., DHTs - do not require or assume any structure on the underlying network topology; (2) efficient and resilient techniques for sophisticated querying of P2P namespaces in unstructured environments; and (3) methods that allow peers to explicitly incorporate individual trust and privacy policies into protocol actions. The work is terms of four applications: (1) an ad-hoc public key infrastructure; (2) a robust search and query application for distributed data; (3) a censorship-resistant publishing application; and (4) an application for efficient ad-hoc access to scientific datasets.Individually, each of these applications are important building blocks that exercise different aspects of our proposed work, and directly advance the state of the art in the sciences, engineering, and national security. Together, they form a compelling set of motivating examples for the research to be conducted under this project.

拟议的工作的目的是为完全非结构化，分散和分布式网络建立一个基础，以启用丰富的应用程序。最近，在点对点系统的背景下，在相似平台上构建了许多不同的研究应用程序。尽管这些研究系统提供了巨大的希望，但我们认为为了在这些系统上构建可部署的应用程序需要大量工作。这项工作是由该领域的开放问题激励的，并将其组织为三个主要的推力：（1）与一系列对抗性失败模型相对可靠的放置和查找算法，但与DHTS相比，DHTS-不需要或不需要任何结构或在基础网络拓扑上进行任何结构； （2）在非结构化环境中对P2P名称空间进行复杂查询的有效和弹性技术； （3）允许同行将个人信任和隐私政策明确纳入协议行动的方法。工作是四个应用程序的条款：（1）临时公共密钥基础架构； （2）针对分布式数据的强大搜索和查询应用程序； （3）耐心制度的出版应用程序； （4）一个有效临时访问科学数据集的应用程序。在个人的情况下，这些应用程序都是重要的基础，它们在我们提议的工作中行使不同方面，并直接在科学，工程和国家安全中直接提高了最新技术。他们共同形成了一组引人注目的激励示例，以在此项目下进行研究。
