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.

移动的和云计算方面的进展导致设备数量不断增加，容量、功能和使用方式日益多样化。此外，用于用户交互的在线社交网络（OSN）的广泛采用指向了未来，其中应用越来越需要在分布式个人设备之间以及跨社交对等体的设备进行通信的能力。这些设备不仅要无缝地相互通信，而且要安全地相互通信。然而，设备的数量、移动性和多样性的增加带来了越来越多的挑战。在企业环境之外，用户通常仍然负责管理他们自己的设备，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，一种基于覆盖对等网络（P2P）的新方法通过利用OSN作为用户和设备发现以及建立私有通信信道的基础，允许Internet用户无缝地建立连接他们自己的个人设备并扩展到他们信任的对等设备的虚拟专用网络的网络。PerSoNet是一种非结构化的P2P覆盖，其拓扑结构是来自个人设备链接和社交网络关系。它支持各种个人设备之间的私人端到端通信，利用社交关系来发现和设置社交对等体之间的私人消息传递通道，并应用网络虚拟化技术来支持未经修改的软件。因此，现有的和未来的应用可以在个人设备网络内和跨社交对等体进行私密通信，将朋友连接抽象为网络链接，而不会放弃使用现有的OSN来无缝地发现和管理关系，并使用公知的网络抽象和编程原语向开发人员公开。具体而言，PerSoNet在个人设备集合中公开了第2层虚拟网络抽象，并且在社交网络用户的设备之间公开了第3层抽象，从而提供了支持现有和未来应用的基础。该项目通过定量研究，使用模拟技术以及通过软件原型和实际应用和系统的实验推进系统设计和实施的最新技术来研究新的叠加技术。该项目有可能影响大量OSN用户的应用程序，包括私人数据共享，同行之间的私人通信，以及灾难和审查的通信系统。PerSoNet软件将提供给系统研究社区，开源开发人员和广大公众。
