CSR: Small: Leveraging Physical Side-Channels for Good

物联网和网络物理系统越来越多地应用于工业和住宅环境，为智能家居，传感器网络和智能制造开辟了新的机会。虽然这类计算设备的能力越来越强，但通常资源有限，能源和数据存储有限。因此，这些设备中常用的关键应用程序（如通信和调试）必须经过精心设计，以最大限度地降低能耗、性能和面积开销，同时兼顾这些系统中软件和硬件的多样性。该项目的创新之处在于提出了新的方法，用于实现物联网系统中的低功耗低开销通信，指纹识别和调试。所有提出的解决方案中的共同见解是，不是为了实现特定的功能而强加额外的开销（例如，通信或调试），我们利用由系统创建的无意物理信号（称为侧通道）来实现所需的功能。因此，我们能够提出创新和完全不同的方法。该项目的更广泛的意义和重要性在于，所提出的解决方案具有更低的能源，性能和区域存储开销，因为它消除了设备上额外的基础设施的需要，以实现所需的功能，同时适用于广泛的系统。该项目的目标是制定一个研究议程，开发技术和系统，以解决物联网系统的根本挑战。这个建议的关键思想是利用目标系统无意中创建的物理侧通道，以达到有用的目的。具体而言，本研究旨在实现三个主要目标：（一）我们设计了一种新的方法来发送和接收数据使用边信道。该方法仅依赖于软件，开销极低. (ii)我们开发了一种新的设备检测和认证策略，仅依赖于物理侧信道，而不是在最先进的技术中广泛使用的平均射频信号。（iii）我们提出了一种新的方法，通过使用物理侧信道来调试物联网设备。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进行评估，被认为值得支持和更广泛的影响审查标准。

Internet-of-things and cyber-physical systems are becoming increasingly applicable in industrialand residential environments, opening up new opportunities for smart homes, sensor networks,and smart manufacturing. While becoming progressively more capable, this class of computingdevices is typically resource-constrained with limited energy and data storage. It is thusimperative that critical applications commonly used in these devices, such as communicationand debugging, be carefully designed to have minimal energy, performance, and area overheadwhile embracing the diversity of software and hardware present within these systems. Theproject’s novelties are presenting new approaches for enabling low-power low-overheadcommunication, fingerprinting, and debugging in internet-of-things systems. The commoninsight in all the proposed solutions is, instead of imposing additional overhead for achieving aparticular functionality (e.g., communication or debugging), we leverage unintentional physicalsignals created by the system (called side-channels) to enable the desired functionalities. As aresult, we are able to propose innovative and radically different methods. The project's broadersignificance and importance is that the proposed solutions enjoy lower energy, performance,and area storage overheads since it eliminates the need for additional infrastructure on thedevice to achieve the required functionality while being applicable to a wide range of systems.The objective of this project is to set out a research agenda for developing techniques andsystems for addressing the fundamental challenges of internet-of-things systems. The key ideain this proposal is to leverage physical side-channels, unintentionally created by the targetsystem, for useful purposes. Specifically, this research aims to fulfill three major objectives: (i)we design a new method for transmitting AND receiving data using side-channels. The proposedmethod relies only on software and is extremely low overhead. (ii) We develop a new strategyfor device detection and authentication by relying only on physical side-channels as opposed toleveraging radio frequency signals which are extensively used in the state-of-the-art. (iii) Wepropose a new method for debugging Internet of Things devices by using physical side-channels.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.
