CT-ISG: A Framework for Trustworthy Cooperative P2P Applications

点对点(P2P)系统的出现使得在互联网上快速部署互联网规模的分布式应用成为可能。这个项目的重点是合作的对等系统，在这个系统中，对等节点形成一个具有共同目标和互惠互利的“共同利益共同体”。协作P2P系统能够支持的服务覆盖了网络应用和分布式计算的范围。由于协作P2P系统的价值和效用在于它为用户提供的服务，因此即使存在潜在的不可信任节点，确保其正确高效地运行也是至关重要的。该项目的目标是了解和解决在构建大规模、健壮、可信任、可问责和安全的协作P2P系统方面的挑战和问题。该项目包括几个创新概念和机制的开发实现：高效和正确的“分布式哈希表”路由，随机轮换的“见证”节点，以及虚拟协议评估。

The emergence of peer-to-peer (P2P) systems has enabled rapiddeployment of Internet-scale distributed applications over theInternet. This project focuses on cooperative peer-to-peer systems, inwhich peer nodes form a "community of common interest" with sharedgoals and mutual benefits. Services that can be supported bycooperative P2P systems cover the gamut of networkedapplications and distributed computing. Since the value and utility of a cooperative P2P system is in theservice it offers to its users, ensuring its correct and efficientoperation despite the existence of potentially untrustworthy nodes isof utmost importance. The goal of this project is to understand and address the challengesand problems in building large-scale, robust cooperative P2P systemsthat are trustworthy, accountable and secure. The project includesdeveloping implementations of several innovative concepts andmechanisms: efficient and correct "Distributed Hash Table" routing,randomly rotating "witness" nodes, and virtualized protocolevaluation.
