随着物联网 (IoT) 越来越普遍并部署在关键应用中，物联网设备相互通信时保护敏感数据的机密性变得越来越重要。然而，传统的密码学通常耗费时间和精力。它可能不适用于计算能力或功率有限的物联网设备。在本文中，我们受到一次性 pad 加密的启发，提出了一种名为动态无线通道 P ad (DyWCP) 的轻量级加密方案。一次性一密加密虽然实现了完美的保密性，但由于密钥协商的不便，在实际中很少使用。我们的研究发现，在无线环境中，可以设计一种无需密钥协商的一次性密码本加密方案。为了实现 DyWCP，我们创建了利用无线信道的附加功能来加密消息、在无线物理层集成模块化操作以及防御多个窃听者的技术。我们使用通用软件定义无线电外设（USRP）实现了所提出方案的原型，并进行了一系列实验来评估所提出方案的性能。
As Internet of Things (IoT) is more and more pervasive and deployed in critical applications, it's becoming increasingly important to preserve the confidentiality of sensitive data when IoT devices communicate with each other. However, traditional cryptography is usually time and energy consuming. It may not be applicable to IoT devices with limited computational capability or limited power. In this paper, we propose a lightweight encryption scheme named Dynamic Wireless Channel P ad (DyWCP) inspired by one-time pad encryption. One-time pad encryption achieves perfect secrecy but has been rarely used in practice due to the inconvenience of key negotiation. Our research discovers that in the wireless context it is possible to design a one-time pad encryption scheme without key negotiation. Towards the realization of DyWCP, we create techniques to utilize the additive feature of wireless channel to encrypt messages, to integrate modular operations at wireless physical layer, and to defend against multiple eavesdroppers. We implement a prototype of the proposed scheme using Universal Software Defined Radio Peripherals (USRP), and conduct a suite of experiments to evaluate the performance of the proposed scheme.
