NetSE: Medium: Collaborative Research: Privacy Preserving Social Systems

未来互联网的成功将不仅仅以性能来衡量，而是以其改变我们生活质量的社会和社会影响来衡量。下一代互联网不仅必须连接机器，还必须连接用户：家人和朋友，代表和权利倡导者。在促进通信的同时保护用户隐私并保护其安全性方面存在巨大的技术挑战。我们应对三个关键挑战。首先，我们将以用户为中心的研究应用于开发朋友之间的实用安全通信，为社交消息传递奠定基础，而无需信任中心化机构来提供身份。其次，我们开发先进的加密技术来处理私人数据，而不会将其泄露给应用程序提供商，从而为私人社交应用程序奠定坚实的理论基础。最后，我们建议通过将社交网络数据嵌入到应用程序的设计中，从根本上改变分布式应用程序中鼓励合作和惩罚不当行为的方式。社交网络非常受欢迎，维护隐私是这些系统中的一个重要问题。对隐私的渴望阻止了个人充分参与，并使那些参与的人容易受到各种问题的影响，包括潜在的身份盗窃。由于问题和问题域的重要性，我们的研究结果将产生重大的公众影响。研究生和本科生工作在这个建议将获得经验与社会应用，评估加密协议，并建立系统，结合联合收割机社会数据。我们积极参与本科生在我们的研究，并希望继续下去。

The success of the future Internet will not be measured by performance alone, but by its social and societal effects that alter our quality of life. The next-generation Internet must connect not only machines but also users: families and friends, representatives and rights advocates. There are immense technical challenges in facilitating communication while protecting user privacy and guarding their security. We address three key challenges. First, we apply user-focused research into developing practical secure communication between friends, laying the groundwork for social messaging without trusting centralized authorities to provide identities. Second, we develop advanced cryptographic techniques for processing private data without divulging it to application providers, placing private social applications on a solid theoretical foundation. Finally, we propose to fundamentally change how cooperation is encouraged and misbehavior is punished in distributed applications by embedding social network data into the design of applications.This work has important broader impacts. Social networking is incredibly popular and maintaining privacy is a significant problem within these systems. The desire for privacy prevents individuals from participating fully and makes those who do participate vulnerable to various problems including potential identity theft. Because of the importance of the problem and problem domain, the results of our research will have significant public impact. Graduate and undergraduate students working on this proposal will gain experience with social applications, evaluating cryptographic protocols, and building systems that combine social data. We have actively involved undergraduate students in our research, and expect to continue.
