项目摘要

During the past decade, cryptographers have identified several directions to meet future security demands like secure outsourced environments, robustness against non-traditional attacks, and post-quantum crypto systems. Despite many exciting advances, many of these instantiations are still far from practical, which reduces their potential impact. This project will provide critical thrusts towards reducing these restrictions in order to make these techniques more applicable in practice. This project introduces new research-intensive courses on homomorphic computation, defines appropriate research activities for training students, and has numerous outreach activities to underrepresented groups including middle school students. This project focuses on improving two significant classes of lattice-based cryptography: (1) homomorphic computation, and (2) security against non-traditional attacks. These two classes provide powerful tools to secure data in both outsourced and portable environments, and additionally achieve post-quantum security. Particularly, this project starts with several recently developed techniques that connect homomorphic computation with (1) improved efficiency of identity-based encryption, (2) tighter/stronger security, and (3) non-traditional attacks. The objective is to refine these recent approaches and design practically efficient solutions. The outcomes would yield multiple efficient post-quantum crypto systems, contributing to further post-quantum standardizations, and providing secure methods for more advanced applications. Techniques developed in this project are expected to bring critical insights for making a leap towards the general goal, aiming at building truly practical solutions for all homomorphic computation and security against non-traditional attacks.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.

在过去的十年中，密码学家已经确定了满足未来安全需求的几个方向，例如安全的外包环境、针对非传统攻击的鲁棒性以及后量子密码系统。尽管取得了许多令人兴奋的进步，但其中许多实例仍然距离实用还很远，这降低了它们的潜在影响。该项目将为减少这些限制提供关键推动力，以使这些技术在实践中更适用。该项目引入了有关同态计算的新研究密集型课程，为培训学生定义了适当的研究活动，并对包括中学生在内的弱势群体开展了许多外展活动。该项目专注于改进两类重要的基于格的密码学：(1) 同态计算，以及 (2) 针对非传统攻击的安全性。这两个类别提供了强大的工具来保护外包和便携式环境中的数据，并另外实现后量子安全。特别是，该项目从最近开发的几种技术开始，这些技术将同态计算与（1）提高基于身份的加密的效率，（2）更严格/更强的安全性以及（3）非传统攻击联系起来。目标是完善这些最新方法并设计实用有效的解决方案。结果将产生多个高效的后量子加密系统，有助于进一步的后量子标准化，并为更高级的应用程序提供安全的方法。该项目开发的技术预计将为实现总体目标带来重要见解，旨在为所有同态计算和非传统攻击的安全性构建真正实用的解决方案。该奖项反映了 NSF 的法定使命，并被认为是值得的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来提供支持。
