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.

移动和云计算的进步导致设备数量不断增加，容量、功能和使用方式也越来越多样化。此外，用于用户交互的在线社交网络 (OSN) 的广泛采用预示着未来，应用程序越来越需要在分布式个人设备之间以及社交同伴之间进行通信的能力。对于这些设备来说，彼此之间的通信不仅要无缝而且要安全，这一点至关重要。然而，设备数量、移动性和多样性的增加带来了越来越大的挑战。在企业环境之外，用户通常仍然负责管理自己的设备，这是复杂且容易出错的。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) 网络的新颖方法，允许互联网用户无缝建立虚拟专用网络，连接他们自己的个人设备，并通过利用 OSN 扩展到其可信同伴的设备作为用户和设备发现以及建立专用通信通道的基础。PerSoNet 是一种非结构化 P2P 覆盖，其拓扑源自个人设备链路和社交网络关系。它支持各种个人设备之间的私有端到端通信，利用社交关系来发现和设置社交同伴之间的私有消息通道，并应用网络虚拟化技术来支持未经修改的软件。因此，现有和未来的应用程序可以在个人设备网络内和跨社交同伴进行私密通信，将朋友连接抽象为网络链接，而不会放弃使用现有 OSN 来无缝发现和管理关系，并使用众所周知的网络抽象和编程进行公开给开发者的原语。具体来说，PerSoNet 公开了一组个人设备之间的第 2 层虚拟网络抽象，以及跨社交网络用户设备的第 3 层抽象，为支持现有和未来的应用程序提供了基础。该项目通过定量研究、使用模拟技术来研究新颖的叠加技术，并通过软件原型和现实应用程序和系统的实验来推进最先进的系统设计和实现。该项目有可能影响大量 OSN 用户的应用，包括私有数据共享、同行之间的私有通信以及抗灾难和抗审查通信系统。 PerSoNet 软件将向系统研究社区、开源开发人员和广大公众开放。
