本文介绍了物理不可克隆功能 (PUF) 在低成本身份验证和密钥生成应用中的使用。首先，它推动 PUF 与传统安全非易失性存储器的使用，并定义了两种主要的 PUF 类型：“强 PUF”和“弱 PUF”。它描述了强 PUF 实现及其在低成本身份验证中的使用。在此描述之后，本文涵盖了攻击和解决错误的协议。接下来，本文介绍了弱 PUF 实现及其在密钥生成应用程序中的使用。它涵盖了纠错方案，例如模式匹配和基于索引的编码。最后，本文回顾了 PUF 技术中的几个新兴概念，例如公共模型 PUF 和新的 PUF 实现技术。
This paper describes the use of physical unclonable functions (PUFs) in low-cost authentication and key generation applications. First, it motivates the use of PUFs versus conventional secure nonvolatile memories and defines the two primary PUF types: "strong PUFs'' and "weak PUFs.'' It describes strong PUF implementations and their use for low-cost authentication. After this description, the paper covers both attacks and protocols to address errors. Next, the paper covers weak PUF implementations and their use in key generation applications. It covers error-correction schemes such as pattern matching and index-based coding. Finally, this paper reviews several emerging concepts in PUF technologies such as public model PUFs and new PUF implementation technologies.
