In recent years, the ubiquitous nature of Internet-of-Things (IoT) applications as well as the pervasive character of next-generation communication protocols, such as the 5G technology, have become widely evident. In this work, we identify the need for low-cost security in current and next-generation IoT networks and address this demand through the implementation, testing, and validation of an intrinsic low-cost and low-overhead hardware-based security primitive within an inherent network component. In particular, an intrinsic Physical Unclonable Function (PUF) is implemented in the peripheral network module of a tri-band commercial off-the-shelf router. Subsequently, we demonstrate the robustness of this PUF to ambient temperature variations and to limited natural aging, and examine in detail its potential for securing the next generation of IoT networks and other applications. Finally, the security of the proposed PUF-based schemes is briefly assessed and discussed.

下一代物联网网络的低成本安全性

近年来，物联网 (IoT) 应用的普遍性以及下一代通信协议（如 5G 技术）的普遍特征已变得越来越明显。在这项工作中，我们确定了当前和下一代物联网网络对低成本安全性的需求，并通过在一个内部低成本和低开销的基于硬件的安全原语的实施、测试和验证来满足这一需求。固有的网络组件。特别是，在三频商用现成路由器的外围网络模块中实现了固有的物理不可克隆功能（PUF）。随后，我们展示了这种 PUF 对环境温度变化和有限自然老化的稳健性，并详细检查其在保护下一代物联网网络和其他应用程序方面的潜力。最后，简要评估和讨论了所提出的基于 PUF 的方案的安全性。
