论文摘要
物理上的不元件功能（PUF）是资源受限的物联网设备的有前途的安全性基础。而Xor Arbiter PUF（XOR-PUF）是研究最多的PUF之一，出于提高对机器学习攻击的抵抗力，可能是基于最轻巧的延迟PUF-Arbiter PUF。但是，最近的攻击研究表明，即使是XOR尺寸较大的XOR-PUFS仍然不安全，可以防止机器学习攻击。增加PUF阶段或组件以及针对不同组件的不同挑战是提高基于APUF的PUF安全性的两种方法，但是更多的阶段或组件会导致更高的硬件成本和更高的操作功率，以及对不同组件的不同挑战需要在操作过程中传输更多位，这也导致更高的功耗。在本文中，我们提出了一种策略，该策略结合了XOR ARBITER PUF（XOR-PUF）体系结构参数与XOR-PUF的使用方式来实现硬件成本和能源消耗的轻量级，以及防止机器学习攻击的安全性。实验评估表明，借助提出的策略，高度轻巧的组件分差呈挑战性XOR-PUF可以承受到目前为止开发的最强大的机器学习攻击，并保持出色的设备内和设备间的性能，从而使该策略成为用于制造和使用XOR-PUF的XOR-PUF的潜在蓝图，以用于XOR-PUF，以实现XOR-PUF，以实现XOR-PUF，以实现IOT构成的IOT IOT应用程序。
Physical Unclonable Functions (PUFs) are promising security primitives for resource-constrained IoT devices. And the XOR Arbiter PUF (XOR-PUF) is one of the most studied PUFs, out of an effort to improve the resistance against machine learning attacks of probably the most lightweight delay-based PUFs - the Arbiter PUFs. However, recent attack studies reveal that even XOR-PUFs with large XOR sizes are still not safe against machine learning attacks. Increasing PUF stages or components and using different challenges for different components are two ways to improve the security of APUF-based PUFs, but more stages or components lead to more hardware cost and higher operation power, and different challenges for different components require the transmission of more bits during operations, which also leads to higher power consumption. In this paper, we present a strategy that combines the choice of XOR Arbiter PUF (XOR-PUF) architecture parameters with the way XOR-PUFs are used to achieve lightweights in hardware cost and energy consumption as well as security against machine learning attacks. Experimental evaluations show that with the proposed strategy, highly lightweight component-differentially challenged XOR-PUFs can withstand the most powerful machine learning attacks developed so far and maintain excellent intra-device and inter-device performance, rendering this strategy a potential blueprint for the fabrication and use of XOR-PUFs for resource-constrained IoT applications.
