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.

未来互联网的成功不会仅通过绩效来衡量，而是通过改变我们生活质量的社会和社会影响。下一代互联网不仅必须连接机器，还必须连接用户：家人，朋友，代表和权利倡导者。在保护用户隐私并保护其安全性的同时，促进沟通方面存在巨大的技术挑战。我们应对三个主要挑战。首先，我们将以用户为中心的研究应用于朋友之间的实践安全沟通，为社会消息开展基础，而无需信任集中式当局提供身份。其次，我们开发了用于处理私人数据的高级加密技术，而无需将其泄露给应用程序提供商，从而将私人社交应用程序置于坚实的理论基础上。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，从根本上改变如何鼓励合作，并在分布式应用程序中受到惩罚。这项工作具有更大的广泛影响。社交网络非常受欢迎，并且在这些系统中保持隐私是一个重要的问题。对隐私的渴望阻止个人完全参与，并使那些确实参与各种问题的人，包括潜在的身份盗用。由于问题和问题领域的重要性，我们的研究结果将产生重大的公众影响。从事该建议的研究生和本科生将获得有关社交应用，评估密码协议以及结合社交数据的建筑系统的经验。我们已经积极参与本科生的研究，并希望继续。
