As the prevalence of mobile computing technologies and applications, short-range communication over emerging aerial acoustic and visible light channel is undergoing a fast rate of expansion with many promising benefits including low power and peer-to-peer communication, without incurring complex network infrastructure. Although those short range wireless channels have an inherent and physical protection against many malicious attacks, the confidentiality of the data transmission against eavesdropping remains a risk, motivating considerable interest in the security of short range communication. Unlike traditional cryptographic methods that rely on central security management infrastructure to secure wireless links, this project proposes to obfuscate the transmitting wireless signals by incorporating random channel dynamics to defend against eavesdroppers. Specifically, based on specific wireless channel characteristics, different channel obfuscation schemes are to be developed to achieve information-theoretic secrecy with respect to aerial acoustic and visible light channels. The proposed research will also contribute to interdisciplinary education on wireless security for both graduate and undergraduate students.This proposal aims to enhance physical layer security for short range wireless communications over acoustic and visible light channels. The research reveals that the unique characteristics of different types of wireless channels can be exploited to perform channel obfuscation for protecting secrecy against eavesdropping attacks. Particularly, for acoustic channels, this project develops the channel obfuscation scheme relying on self-jamming signals emitted by the legitimate receiver to secure short-range communication. Moreover, a novel communication protocol based on time-difference-of-arrival modulation is introduced to achieve accurate and robust data transmission. For visible light communication, a channel obfuscation scheme is developed for screen-to-camera channels to realize a secure secret key distribution leveraging the color shift property of Liquid Crystal Display and Light-Emitting Diode screens.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

随着移动计算技术和应用的盛行，对新兴空中声学和可见光通道进行的短距离通信正在快速扩张，并具有许多有希望的好处，包括低功率和点对点通信，而不会产生复杂的网络基础架构。尽管这些短距离无线渠道具有针对许多恶意攻击的固有和物理保护，但针对窃听的数据传输的机密性仍然是一种风险，激发了对短距离通信的安全性的巨大兴趣。与依靠中央安全管理基础架构保护无线链接的传统加密方法不同，该项目提议通过合并随机通道动力学来防御窃听窃听器来混淆传输无线信号。具体而言，基于特定的无线通道特性，应开发不同的通道混淆方案，以实现有关空气和可见光通道的信息理论保密。拟议的研究还将为研究生和本科生的无线安全跨学科教育做出贡献。该提案旨在提高与声学和可见光频道的短距离无线通信的物理层安全性。该研究表明，可以利用不同类型的无线通道的独特特性进行通道混淆，以保护保密性免受窃听攻击。特别是，对于声学渠道，该项目开发了依靠合法接收器发出的自我判断信号来确保短期通信的频道混淆方案。此外，引入了基于时间差异调制的新型通信协议，以实现准确且健壮的数据传输。对于可见光的沟通，为屏幕到相机频道开发了一种通道混淆方案，以实现一个安全的秘密钥匙分布，利用液晶显示屏和发光二极管屏幕的色移特性。这项奖项反映了NSF的法定任务，并被认为是通过基金会的智力功能和广泛影响的评估来评估CRETERIA的评估。
