This project will develop techniques for trusted systems that can provide correct information and take correct actions when needed and where needed. The focus will be on peer-to-peer (P2P) systems, where computers or nodes operate autonomously, without any central control. In a P2P system, each node provides storage and compute resources. It connects to other neighbor nodes, and the community provides services like file sharing, document archiving, or data analysis.P2P systems are especially well suited as the "backbone" of a trusted system because nodes operate independently, without reliance on particular network connections or on nodes with a fixed functionality. Thus, a P2P system can adapt to a changing environment, and with the proper mechanisms, can isolate or ignore malicious nodes.As part of the project, several important problems will be addressed such as: Denial of Service (DoS): How does one protect against malicious sites that generate excess load to prevent others from receiving resources or service?Searching: How does one efficiently find information without using centralized index facilities, and in a dynamically changing environment? Information Authenticity: How does one verify the authenticity of documents or information? Preservation: How does one preserve information past the lifetime of the originating node?The proposed research is high risk, but there is also the potential for a large payoff. The research is high risk because the problems faced are difficult: Building a trusted community out of building blocks that may be transient and malicious, is not an easy task. However, the only way to build a trusted system is, as proposed, by making as few assumptions as possible about the trustworthiness of its components. The techniques to be developed, if successful, will provide a solid foundation for building truly reliable, secure, and trusted systems for electronic commerce, military applications, healthcare, and many other applications.

该项目将为受信任的系统开发技术，这些技术可以提供正确的信息并在需要时和需要时采取正确的操作。 重点将放在点对点（P2P）系统上，该系统在没有任何中央控制的情况下自动运行的计算机或节点。 在P2P系统中，每个节点都提供存储和计算资源。它连接到其他邻居节点，社区提供了诸如文件共享，文档归档或数据分析之类的服务。P2P系统特别适合作为受信任系统的“骨干”，因为节点可以独立运行，而无需依赖特定网络连接或具有固定功能的节点。 因此，p2p系统可以适应不断变化的环境，并有了适当的机制，可以隔离或忽略恶意节点。作为项目的一部分，将解决一些重要问题，例如：拒绝服务（DOS）：一个人可以防止恶意网站免受恶意网站的影响，以免产生过多的负载，以防止其他人获得有效的环境：index and Offical intermity interivility interivily interive and interivility interex and Index and Index and Index and Index and Index and Index，以及A的中心化，A A的中心化？信息真实性：如何验证文档或信息的真实性？保存：一个人如何保存信息超过原始节点的寿命？拟议的研究是高风险，但也有可能带来巨大的回报。 该研究是高风险，因为面临的问题很困难：从可能是短暂和恶意的基础上建立一个受信任的社区，这不是一件容易的事。 但是，构建受信任系统的唯一方法是通过对其组件的可信度做出尽可能少的假设来提议。如果成功的话，将开发的技术将为建立真正可靠，安全和可信赖的系统来为电子商务，军事应用，医疗保健和许多其他应用提供稳固的基础。
