This research project develops ideas and designs that can be used to fingerprint or authenticate computer hardware, to generate cryptographic keys, or form basis of new security protocols, all leveraging the physical properties of the computer hardware. Especially, the focus of this research is on commodity memories found in today's computers, and the work advances fundamental understanding of how the physical properties of memories can be used in computer security. By focusing on hardware already present in commodity computing devices, the ideas developed in this research can be readily deployed. Through development of professional and educational activities, and interaction with international colleagues, this project also supports dissemination of research ideas to a broad audience.To advance the hardware security research field, this research project explores the cell decay effects in Dynamic Random Access Memories (DRAMs) and applies them to the design of DRAM-based Physically Unclonable Functions (PUFs), as well as to development of new virtual proofs of reality and Physical Cryptography primitives, all based on commodity DRAMs. Through design of a manual refresh approach, this research shows how the DRAM's properties can be measured even if DRAM is part of a commodity computer system and actively used by software. Environmental impacts on DRAM are also evaluated and understanding is developed of how the environment affects DRAM-based security primitives. In addition, this research tackles challenges such as theoretical and mathematical issues of developing error correction schemes for use with DRAM PUFs, or practical issues of accelerating DRAM PUF readout time.

该研究项目开发了可用于指纹或身份验证计算机硬件，生成加密密钥或形成新安全协议的基础的思想和设计，所有这些都利用了计算机硬件的物理属性。 尤其是，这项研究的重点是在当今计算机中发现的商品记忆，而作品促进了对如何在计算机安全中使用记忆的物理特性的基本理解。 通过专注于商品计算设备中已经存在的硬件，可以很容易地部署本研究中发展的想法。通过开发专业和教育活动以及与国际同事的互动，该项目还支持向广泛的受众传播研究思想。为了推进硬件安全研究领域，该研究项目探索了动态随机访问记忆（DRAM）中细胞衰减的影响（DRAM），并将其应用于基于DRAM的物理性能（PUFS）以及新的Viraction（PUFS），以及新的事实（PUFS），以及新的事实，并开发了新的美德（PUFS）。戏剧。 通过设计手动刷新方法，该研究表明，即使DRAM是商品计算机系统的一部分，并且由软件主动使用，即使DRAM是如何衡量DRAM的属性的。 还评估了对DRAM的环境影响，并了解了环境如何影响基于DRAM的安全性原料。 此外，这项研究解决了开发用于DRAM PUF的错误校正方案的理论和数学问题等挑战，或加速DRAM PUF读数时间的实际问题。
