CAREER: Utilizing Principles of Energy Recovery Computing for Low-Energy and DPA-Resistant IoT Devices

该项目将开发能量回收电路的电路设计技术和此类设计单元库，以促进移动物联网（IoT）设备的低功耗分组密码实现，其中降低功耗至关重要。设计挑战是生产低能耗、轻量级和安全的设备，这些设备还可以抵御恶意攻击，恶意攻击利用功耗跟踪提取私人或敏感信息。该项目将为抗低能耗和差分功率分析（DPA）的物联网设备提供一套能量回收（ER）原则。研究目标是：(i)调查ER电路中的信息泄漏并提出缓解方法；（ii）研究和开发用于轻量级加密电路的低能量和抗dpa的ER标准单元库和半定制设计流程；（iii）研究和开发功率时钟的产生和分配，以及硅原型，以评估基于er的加密电路的能量耗散和dpa电阻。该项目的成果和成果将为行业采用ER计算设计低能耗和安全的物联网设备提供强有力的案例。该项目的另一个整体目标是扩大研究生、本科生、少数民族和代表性不足的人对网络和硬件安全研究和教育的参与。该项目将为本科生和研究生开发硬件安全方面的新课程，并举办研讨会。硬件安全方面的实习机会将提供给阿巴拉契亚地区的高中生、历史上未被充分代表的少数族裔和第一代学生。项目储存库将以电子方式存储，并通过肯塔基大学工程学院主办的网站（http://hthapliyal.engineering.uky.edu/）提供。这些数据将在合同期限之后至少保留三年。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This project will develop circuit design techniques for energy-recovery circuits and a library of such design cells to facilitate low-power implementation of block cipher for mobile Internet-of-Things (IoT) devices, where reducing power consumption is critical. The design challenge is to produce low-energy, lightweight, and secure devices, which are also resistant against malicious attacks that use power consumption traces to extract private or sensitive information. This project will provide a set of energy recovery (ER) principles for low-energy and differential power analysis (DPA)-resistant IoT devices. The research objectives are: (i) to investigate information leakage in ER circuits and propose mitigation methodologies; (ii) to investigate and develop a low-energy and DPA-resistant ER standard cell library and semi-custom design flow for lightweight cryptographic circuits; and (iii) to investigate and develop power clock generation and distribution, and silicon prototyping to evaluate energy dissipation and the DPA-resistance of ER-based crypto circuits. Outcomes and results from this project should make a strong case for industry adoption of ER computing for the design of low-energy and secure IoT devices. Another integral goal of this project is to broaden graduate, undergraduate, and minority and underrepresented participation in cyber and hardware security research and education. The project will develop new courses in hardware security for undergraduate and graduate students, and conduct workshops. Internships on hardware security will be offered to Appalachian high-school students and historically underrepresented minorities, and first-generation students. The project repository will be stored electronically and made available through the website hosted by University of Kentucky, College of Engineering (http://hthapliyal.engineering.uky.edu/). The data will be retained for at least three years beyond the duration of the award.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.
