A detailed review on the technological aspects of Blockchain and Physical Unclonable Functions (PUFs) is presented in this article. It stipulates an emerging concept of Blockchain that integrates hardware security primitives via PUFs to solve bandwidth, integration, scalability, latency, and energy requirements for the Internet-of-Energy (IoE) systems. This hybrid approach, hereinafter termed as PUFChain, provides device and data provenance which records data origins, history of data generation and processing, and clone-proof device identification and authentication, thus possible to track the sources and reasons of any cyber attack. In addition to this, we review the key areas of design, development, and implementation, which will give us the insight on seamless integration with legacy IoE systems, reliability, cyber resilience, and future research challenges.
本文详细回顾了区块链和物理不可克隆函数（PUF）的技术方面。它规定了区块链的一个新兴概念，即通过 PUF 将硬件安全原语集成到区块链中，以解决能源互联网（IoE）系统的带宽、集成、可扩展性、延迟和能源需求。这种混合方法，以下称为 PUFChain，提供了设备和数据来源，可以记录数据的来源、数据生成和处理的历史，以及防克隆设备识别和认证，从而可以跟踪任何网络攻击的来源和原因。除此之外，我们还回顾了设计、开发和实施的关键领域，这将使我们深入了解与传统 IoE 系统的无缝集成、可靠性、网络弹性以及未来的研究挑战。
