This project addresses how semiconductor designers can verify the correctness of ICs that they source from possibly untrusted fabricators. Existing solutions to this problem are either based on legal and contractual obligations, or use post-fabrication IC testing, both of which are unsatisfactory or unsound. As a sound alternative, this project designs and fabricates verifiable hardware: ICs that provide proofs of their correctness for every input-output computation they perform in the field. These proofs must be efficiently verifiable in less time and energy than it takes to re-execute the computation itself.Building upon exciting recent theoretical and practical advances in verifiable outsourced computation for the cloud, this project develops new techniques that exploit the unique constraints and adversary models that relate to the verifiable hardware problem. In addition, the project also develops new practical approaches to the problem of general verifiable computation. As a broader impact, computing systems security is one of the greatest technological problems faced by society today. Verifiable hardware is an essential foundation for building future computing systems that are reliable and free from catastrophic security failures. The ultimate goal of this project is to make verifiable hardware practical and accessible for use in cryptographic and mission-critical hardware applications through open-source tools. The PIs are strongly committed to education and public outreach by producing widely-used course materials and taking active roles in outreach at minority-serving universities, community colleges, student organizations and high schools.

该项目解决了半导体设计人员如何验证他们从可能不受信任的制造商那里采购的 IC 的正确性。 现有的解决方案要么基于法律和合同义务，要么使用制造后的 IC 测试，这两种方法都不能令人满意或不健全。作为一个合理的替代方案，该项目设计并制造了可验证的硬件：为现场执行的每个输入输出计算提供正确性证明的 IC。这些证明必须能够以比重新执行计算本身更少的时间和精力进行有效验证。基于云可验证外包计算方面令人兴奋的最新理论和实践进展，该项目开发了利用独特约束和对手的新技术与可验证的硬件问题相关的模型。此外，该项目还开发了解决通用可验证计算问题的新实用方法。作为更广泛的影响，计算系统安全是当今社会面临的最大技术问题之一。可验证的硬件是构建可靠且不会出现灾难性安全故障的未来计算系统的重要基础。该项目的最终目标是通过开源工具使可验证的硬件实用且易于在加密和关键任务硬件应用中使用。 PI 坚定地致力于教育和公共宣传，制作广泛使用的课程材料，并在少数族裔服务的大学、社区学院、学生组织和高中的宣传活动中发挥积极作用。
