SHF: Small: Hardware-Level Security to Side-Channel Analysis Attacks

计算机固有地容易受到所谓的侧信道安全攻击，这些侧信道安全攻击将它们的操作特性（例如，功耗），其中存储有秘密信息（例如，密码密钥）。 以前的方法，旨在解决这一脆弱性的阻碍了过高的功率，面积和性能开销。该研究项目探索设计安全计算机的技术，使用有可能产生比传统计算硬件更安全的计算设备的技术，在性能，面积和能源效率方面几乎没有牺牲。 该研究工作还包括为高级本科设计课程开发项目，并通过各种推广计划吸引高中生参与。该项目将探索新颖的硬件设计技术，这些技术本身就能抵抗侧信道攻击，同时实现与主流设计技术相比毫不逊色的性能、面积和功率水平。 具体来说，它将探索电路拓扑结构，回收用于其操作的能量，产生上级能源效率和平坦的功耗曲线，是免疫的侧信道攻击。 它还将探索具有面积高效逻辑系列和平坦功耗曲线的流水线架构，可以抵抗侧信道攻击。 该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。

Computers are inherently vulnerable to so-called side-channel security attacks that correlate their operating characteristics (e.g., power consumption) with secret information stored in them (e.g., cryptographic keys). Previous approaches aimed at addressing this vulnerability are hampered by prohibitively-high power, area, and performance overheads. This research project explores technologies for designing secure computers, using technologies that have the potential to yield computing devices that are significantly more secure than conventional computing hardware with little-or-no sacrifice in performance, area, and energy efficiency. This research effort also includes the development of projects for advanced undergraduate-level design courses, and the engagement of high-school students through a variety of outreach programs.This project will explore novel hardware design technologies that are inherently resistant to side-channel attacks while achieving performance, area, and power levels that compare favorably with mainstream design technologies. Specifically, it will explore circuit topologies that recycle the energy used for their operation, yielding superior energy efficiency and a flat power consumption profile that is immune to side-channel attacks. It will also explore pipeline architectures with area-efficient logic families and a flat power consumption profile that can resist side-channel attacks. The proposed technologies will be evaluated through the design, fabrication, and experimental evaluation of silicon prototypes.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.
