Cryptographic protocols have become an essential facilitator for the Internet and its many applications, supporting the needs of modern society. It is hard to imagine the Internet without the extensive use of applied cryptographic protocols, e.g., protocols used to secure web and email. Such protocols use and depend on the Public Key Infrastructure (PKI), which is also key to the security of other open systems such as mobile networks, Internet of Things, and blockchains. PKI provides a critical security infrastructure to achieve confidentiality, authentication, integrity and non-repudiation. However, there have been many attacks exploiting vulnerabilities of the PKI itself; PKI, in contrast to other well-known cryptographic protocols, has no security proofs or even precise definitions of security goals. As a result, systems utilizing PKI may be vulnerable. The proposed research will define security goals for PKI schemes, present PKI schemes which provably meet these goals, and present practical and efficient implementations of PKI schemes. This research will also develop the necessary theoretical tools to define security goals of cryptographic protocols and to analyze their security. The outcomes of this research will have broad benefits. Developers will benefit from the availability of open-source, provably secure PKI systems, enabling security for real-world applications. End-users will benefit from improved security guarantees and privacy. Given the global role of the Internet, society at large will benefit from a strengthened, advanced security infrastructure and PKI ecosystem and from educational efforts which will raise awareness of the importance of these topics. Furthermore, this research will support the development of a diverse cohort of graduate and undergraduate students at the University of Connecticut and Trinity College through increased research opportunities, education, and mentoring and outreach efforts. Research efforts of this project, the results of which will significantly impact the theoretical and practical aspects of developing and deploying cryptographic protocols, are organized in three main areas: 1) Advancement of PKI theory: to define a comprehensive set of formal PKI requirements, and to design and analyze schemes to produce provably secure PKI schemes; 2) Development of PKI systems with improved security guarantees: to design, develop, and standardize provably secure PKI designs that are practical and appropriate for real-world applications; 3) Development of a framework and tools to facilitate provable security for applied cryptographic protocols under realistic models: to build a comprehensive framework that supports composability and formal verification tools for rigorous specification and analysis.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.

加密协议已成为互联网及其许多应用程序的重要促进者，从而支持现代社会的需求。很难想象没有广泛使用的加密协议，例如用于保护网络和电子邮件的协议。此类协议使用并取决于公共密钥基础架构（PKI），这也是其他开放系统（例如移动网络，物联网和区块链）安全的关键。 PKI提供了一个关键的安全基础架构，以实现机密性，身份验证，完整性和非拒绝。但是，有许多攻击利用了PKI本身的漏洞。与其他众所周知的加密协议相比，PKI没有安全目标的安全证明甚至精确的定义。结果，利用PKI的系统可能很脆弱。拟议的研究将定义PKI计划的安全目标，呈现PKI计划，这些计划可实现这些目标，并呈现PKI计划的实际实施实施。这项研究还将开发必要的理论工具来定义加密协议的安全目标并分析其安全性。这项研究的结果将带来广泛的好处。开发人员将受益于开源，可证明的安全PKI系统的可用性，从而为现实世界应用程序提供安全性。最终用户将受益于改善安全保证和隐私。鉴于互联网的全球作用，整个社会将受益于加强，先进的安全基础设施和PKI生态系统以及教育工作，这将提高人们对这些主题重要性的认识。此外，这项研究将通过增加研究机会，教育以及指导和推广工作来支持康涅狄格大学和三一学院的各种研究生和本科生的发展。该项目的研究工作将在三个主要领域中组织和部署加密协议的理论和实际方面，其结果将极大地影响：1）PKI理论的进步：定义一套全面的正式PKI要求，并设计和分析方案以生成可靠的安全PKI Schemes； 2）开发具有改进安全保证的PKI系统：设计，开发和标准化可证明的安全的PKI设计，这些设计是实用且适合现实世界应用程序的； 3）开发一个框架和工具，以促进现实模型下应用的加密协议可证明的安全性：建立一个支持合成性和正式验证工具的全面框架，以进行严格的规范和分析。这项奖项反映了NSF的法定任务，并通过使用该基金会的知识分子优点和广泛的影响来评估NSF的法定任务，并被视为值得的支持。
