物联网在近二十年前被引入，过去二十年技术有巨大进步，可穿戴设备市场不断增长，但对用户隐私和安全构成威胁。本文提出一种用于可穿戴设备的硬件辅助、节能、低开销安全解决方案。具体分析了仲裁器物理不可克隆函数（Arbiter PUF）和混合振荡器仲裁器（HOA）PUF两种架构以集成到物联网系统中。结果表明，Arbiter PUF消耗25微瓦，而HOA PUF生成加密密钥仅消耗2.7微瓦。这些架构在提供强大安全性的同时引入最小的功率开销，非常适合资源受限的物联网生态系统。
英文摘要
The Internet of Things (IoT) was introduced almost two decades ago. In the past two decades, technology has seen huge advancements. Many devices have become powerful and have less power consumption. Many IoT architectures and environments were introduced to help make life easier, especially in wearable devices. The market for these wearable devices has constantly increased over the years and is expected to reach its maximum in the next couple of years. They also pose a threat to users' privacy and security because they constantly store and transmit personal information such as location, heart rate, and other sensitive data. Therefore, addressing the security vulnerabilities is a crucial aspect of this research. This paper presents a hardware-assisted, energy-efficient, low-overhead security solution for wearable devices. Specifically, two Physical Unclonable Function (PUF) architectures: Arbiter PUF and Hybrid Oscillator Arbiter (HOA) PUF are analyzed for integration in IoT systems. The result shows that Arbiter PUF consumes 25 $μ$W, whereas HOA PUF consumes only 2.7 $μ$W to generate keys for cryptographic purposes. These architectures introduce minimal power overhead while providing robust security, making them well suited for resource-constrained IoT ecosystems.
