Progress in mobile and cloud computing leads to an ever-increasing number of devices with increasing diversity in capacity, capabilities and usage modalities. Furthermore, the wide adoption of Online Social Networks (OSNs) for user interaction points to a future where applications increasingly demand the ability to communicate among distributed personal devices, and across those of social peers. It is crucial for these devices to communicate with each other not only seamlessly, but also securely. However, the increased number, mobility and diversity of devices pose ever-increasing challenges. Outside of an enterprise environment, users remain typically responsible for managing their own devices which is complex and error-prone. To address these challenges, this project develops PerSoNet, a novel approach based on overlay peer-to-peer (P2P) networks allowing Internet users to seamlessly establish virtual private networks connecting their own personal devices and extending to devices of their trusted peers by leveraging OSNs as a basis for user and device discovery and for the setup of private communication channels.PerSoNet is an unstructured P2P overlay whose topology is derived from personal device links and social networking relationships. It supports private end-to-end communication among various personal devices, leverages social relationships for the discovery and setup of private messaging channels among social peers, and applies network virtualization techniques to support unmodified software. Thus, existing and future applications can communicate privately within personal device networks and across social peers, abstracting friend connections as network links, without forfeiting the use of existing OSNs for seamless discovery and management of relationships, and exposing using well-known network abstractions and programming primitives to developers. Specifically, PerSoNet exposes a layer-2 virtual network abstraction among the set of personal devices, and a layer-3 abstraction across devices of social network users, providing a basis to support existing and future applications. The project investigates novel overlay techniques with quantitative studies, using simulation techniques and also by advancing the state-of-the-art in systems design and implementation through a software prototype and experiments with realistic applications and systems. This project has the potential to impact a large number of OSN users in applications including private data sharing, private communication among peers, and disaster- and censorship-resistant communication systems. The PerSoNet software will be available to the systems research community, open-source developers, and the public at large.

移动和云计算的进展会导致数量不断增加的设备，其能力和使用方式的多样性增加。此外，用于用户互动的在线社交网络（OSN）的广泛采用指向未来，使应用程序越来越多地要求在分布式个人设备以及社交同行之间进行通信的能力。对于这些设备，不仅可以无缝地互相通信，而且可以牢固地进行通信。但是，设备的数量，流动性和多样性的增加构成了不断增加的挑战。在企业环境之外，用户通常仍负责管理自己的设备复杂且容易出错。为了应对这些挑战，该项目开发了Personet，这是一种基于覆盖点对点（P2P）网络的新方法社交网络关系。它支持各种个人设备之间的私人端到端通信，利用社交同行之间的私人消息传递渠道的发现和设置，并应用网络虚拟化技术来支持未修改的软件。因此，现有的和未来的应用程序可以在个人设备网络和跨社交同行中私下通信，将朋友连接作为网络链接，而无需没收现有的OSN用于无缝发现和对关系的无缝发现和管理，并使用知名网络抽象和对开发人员进行编程原始内容的展示。具体而言，Personet在一组个人设备中揭示了2层虚拟网络抽象，并在社交网络用户的设备之间揭示了第3层抽象，从而提供了支持现有和未来应用程序的基础。该项目使用仿真技术研究了新颖的叠加技术，并通过通过软件原型和实验实验进行了使用现实的应用程序和系统来推进系统设计和实施的最新技术。该项目有可能影响大量的OSN用户在应用程序中，包括私人数据共享，同行之间的私人通信以及灾难和审查耐药的通信系统。 Personet软件将提供给系统研究社区，开源开发人员和整个公众。
