CAREER: Investigating the Impact of Device Aging on the Security of Cryptographic Chips

加密芯片在硬件中实现加密功能，以获得更好的性能。尽管具有显著的性能优势，但攻击者可以通过监视其功耗、篡改其逻辑或将芯片置于压力下生成错误输出来推断敏感数据，从而破坏加密芯片。目前针对此类攻击的保护措施没有考虑到设备的老化，这可能导致设备参数随时间的变化。设备老化可能会危及设备安全。本项目将研究设备老化对加密设备安全性的影响。该项目的目标是了解危及加密设备安全性的与老化相关的风险，特别是那些防止物理攻击的风险，并开发解决方案，以确保在考虑设备老化时的安全性。该项目将重点关注以下威胁并调查老化如何影响它们：(i)最先进的侧信道分析攻击；最先进的故障注入攻击；（iii）硬件木马，其激活可能因老化而容易/强化。它将针对这些方案的缺点，并开发抗老化的对策，以规避侧信道和故障注入攻击。该项目还将研究老化感知木马检测解决方案。该项目的成功将为可信的硬件平台开发持久的安全性，并产生抗老化的安全解决方案，通过在其使用寿命中保持安全的设备使社会受益。为了吸引研究生、本科生和代表性不足的学生参与硬件安全和密码学的研究和教育，该项目将开发一门关于密码学、硬件安全和测试的新课程。将为本科生提供硬件安全方面的指导和实习。该项目还将设法吸引代表性不足的少数民族。将为克里斯多雷耶稣会高中学生组织硬件安全讲座。项目储存库将以电子方式存储，并通过马里兰大学巴尔的摩县计算机科学与电气工程系主办的网站（https://www.csee.umbc.edu/~nkarimi/）提供。这些数据将在资助期结束后至少保留五年。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。

Cryptographic chips implement cryptographic functions in hardware for better performance. Despite the significant performance benefits, cryptographic chips can be compromised by the adversaries via monitoring their power-consumption, tampering their logic or placing the chips under stress to generate erroneous outputs to infer sensitive data. The current protections against such attacks do not consider aging of the devices that can cause parametric shift of device parameters over time. Device aging may potentially compromise device security. This project will investigate the the effects of device aging on the security of cryptographic devices.The goal of this project is to understand the aging-related risks that compromise security of cryptographic devices, particularly those with protection against physical attacks and develop solutions to ensure security when device aging comes into account. This project will focus on the following threats and investigate how aging can affect them: (i) The state-of-the-art side-channel analysis attacks; (ii) The state-of-the-art fault-injection attacks; and (iii) Hardware Trojans whose activation can be facilitated/hardened due to aging. It will target the shortcomings of these schemes and develop aging-resilient countermeasures to circumvent side-channel and fault-injection attacks. This project will also investigate aging-aware Trojan detection solutions.The success of this project will enable the development of long-lasting security for trusted hardware platforms, and result in aging-resistant security solutions that benefit the society via devices that remain secure over their lifetime. To attract graduate, undergraduate, and underrepresented students to hardware security and cryptography research and education, this project will develop a new course on cryptography, hardware security, and testing. Tutorials will be conducted and internships on hardware security will be offered to undergraduate students. This project will also seek to attract underrepresented minorities. Lectures on hardware security will be organized for Cristo Rey Jesuit high-school students. The project repository will be stored electronically and made available through the website hosted by the University of Maryland Baltimore County, department of Computer Science and Electrical Engineering (https://www.csee.umbc.edu/~nkarimi/). The data will be retained for a period of at least five years following the end of the grant period.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.
