The cloud is becoming increasingly integral to our daily lives, the business ecosystem, and society at large. Recently, cutting-edge cryptosystems have been developed that provide the first-ever theoretical solutions to many cloud-related tasks. Such tasks include fine-grained access control to encrypted data, broadcasting to a set of recipients with minimal communication overhead, hiding secrets in public code, and much more. Unfortunately, these recent systems are far from being ready for deployment, due both to significant computational inefficiencies and to new and thus little-understood underlying computational assumptions.This research is bringing cutting-edge cryptographic applications closer to practice by improving the efficiency and security of said applications. A particular focus is program obfuscation, a powerful new tool at the heart of many of the recent theoretical advances in cryptography. This project develops new constructions and security analyses for obfuscation and other related cryptographic tools, yielding more efficient protocols and increasing our confidence in their security. In addition, education is integral to this project, as the PI develops new cryptography courses and advises undergraduates and graduate students alike in order to cultivate the next generation of scholars and practitioners.

云计算正日益成为我们日常生活、商业生态系统和整个社会的一部分。 最近，已经开发出了尖端的密码系统，为许多与云相关的任务提供了有史以来第一个理论解决方案。 这些任务包括对加密数据的细粒度访问控制，以最小的通信开销广播到一组接收者，在公共代码中隐藏秘密等等。不幸的是，这些最新的系统还远远没有准备好部署，由于显着的计算效率低下，以及新的，因此很少了解的基本计算假设。这项研究是通过提高效率和安全性的前沿密码应用程序更接近实践。 一个特别的焦点是程序混淆，这是一个强大的新工具，是密码学最近许多理论进展的核心。 该项目为混淆和其他相关的加密工具开发新的构造和安全分析，产生更有效的协议，并增加我们对其安全性的信心。此外，教育也是该项目不可或缺的一部分，因为PI开发了新的密码学课程，并为本科生和研究生提供建议，以培养下一代学者和从业者。
