CAREER Towards Privacy Preserving Wireless

项目摘要

Ever-growing cyber-attacks can lead to data breaches and exposure of private user data held by third parties, including companies, government entities, or medical institutions. A possible solution to such a risk is to implement privacy-preserving protocols between users and third parties that prevent any private information disclosure in the first place. For instance, a user could prove to a third party that she holds a valid password without revealing the password. While solutions for such privacy-preserving problems exist, such solutions are poorly adapted to the open-access, noisy, bandwidth-limited, and distributed nature of wireless networks. Resorting to privacy-preserving protocols unadapted to wireless communication networks may result in suboptimal/inefficient solutions or, even worse, compromise privacy. This project addresses this challenge with a novel framework for privacy-preserving communication specifically adapted to wireless networks. The anticipated benefits are stronger privacy guarantees, improved data rates, and improved scalability, compared to traditional approaches. The project integrates an educational component in the broad field of cybersecurity under the form of i) graduate student training, ii) project- and research-oriented undergraduate student education, and iii) outreach to K-12 students.This project aims to build a comprehensive framework that will enable the fundamental understanding and design of privacy-preserving wireless communication protocols. The construction of this framework is organized around three thrusts. In the first thrust, to improve data rates and scalability, the project investigates novel building blocks for privacy-preserving protocols that incorporate wireless communication constraints and enable multiuser communication protocols. In the second thrust, the project investigates solutions to make privacy-preserving protocols robust to adversarial behaviors. For instance, legitimate protocol users could exhibit malicious behaviors, or unauthorized network users could launch wireless-specific attacks, such as eavesdropping, jamming, or man-in-the-middle attacks. In the third thrust, the project explores the construction of low-complexity wireless protocols with information-theoretic privacy guarantees via novel coding techniques from coding theory, cryptography, and deep learning.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

不断增长的网络攻击可能导致数据泄露，并暴露第三方持有的私人用户数据，包括公司、政府实体或医疗机构。这种风险的一个可能的解决方案是在用户和第三方之间实施隐私保护协议，以防止任何私人信息泄露。例如，用户可以向第三方证明她持有有效的密码，而不会泄露密码。虽然存在此类隐私保护问题的解决方案，但此类解决方案不能很好地适应无线网络的开放接入、噪声、带宽限制和分布式特性。求助于不适合无线通信网络的隐私保护协议可能会导致次优/低效的解决方案，或者更糟糕的是，损害隐私。该项目通过一种专门适用于无线网络的隐私保护通信的新框架来应对这一挑战。与传统方法相比，预期的好处是更强大的隐私保证、更高的数据速率和更好的可扩展性。该项目整合了广泛的网络安全领域的教育组成部分，其形式包括i)研究生培训，ii)以项目和研究为导向的本科生教育，以及iii)面向K-12学生的扩展。该项目旨在建立一个全面的框架，使人们能够基本理解和设计保护隐私的无线通信协议。这一框架的构建围绕三个方面展开。在第一个推力中，为了提高数据速率和可扩展性，该项目研究了隐私保护协议的新构建块，这些协议结合了无线通信限制并启用了多用户通信协议。在第二个推力中，该项目研究了解决方案，使隐私保护协议对敌对行为具有健壮性。例如，合法协议用户可能会表现出恶意行为，或者未经授权的网络用户可能会发起特定于无线的攻击，例如窃听、干扰或中间人攻击。在第三个重点中，该项目探索了通过来自编码理论、密码学和深度学习的新编码技术来构建具有信息论隐私保证的低复杂性无线协议。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
