Data encryption is a process to transmit sensitive information over a public channel such as a wireless channel, so that only authorized receivers can access it. Unfortunately, digital encryption techniques typically require the use of microprocessors which are power-hungry devices. This project advances the use of alternative analog encryption techniques, such as chaotic encryption. Since analog encryption techniques are more power efficient, this approach makes it possible to avoid the use of microprocessors and consequently facilitate the realization of more portable devices.While the idea of encrypting information via chaotic signals is at least three decades old, only relatively recent technological advancements in circuit fabrication allow the practical implementation of chaotic encryption over a wireless channel. Indeed, one of the main intellectual merits of this project would be the realization of a wireless sensor with integrated encryption on the same chip. Another technological innovation brought by the project is the creation of mechanisms for coordinated communications among multiple devices over the same chaotically encrypted channel using cognitive radio.The impact at large of these methods can be significant. For example, embedding analog encryption techniques in biomedical devices increases the privacy and comfort of patients since data are going to be transmitted wirelessly over a secure channel. Furthermore, autonomous energy-harvesting coin-sized sensors could be easily deployed to monitor large areas requiring minimal maintenance.The results, data and simulation software obtained in this project will be stored on the website https://www.eecs.utk.edu/people/faculty/dmateras/ for at least five years. Software will be released under an open-source license to facilitate the replicability of the results.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.

数据加密是通过公共通道（例如无线通道）传输敏感信息的过程，以便只有授权的接收者才能访问它。不幸的是，数字加密技术通常需要使用微处理器，而微处理器是耗电设备。该项目推进了替代模拟加密技术的使用，例如混沌加密。由于模拟加密技术更加节能，因此这种方法可以避免使用微处理器，从而有助于实现更便携的设备。虽然通过混沌信号加密信息的想法至少已有三十年历史，但只有相对较新的电路制造技术进步才允许在无线信道上实际实现混沌加密。 事实上，该项目的主要智力优点之一是在同一芯片上实现具有集成加密功能的无线传感器。该项目带来的另一项技术创新是创建使用认知无线电在同一混沌加密通道上的多个设备之间协调通信的机制。这些方法的总体影响可能是巨大的。例如，在生物医学设备中嵌入模拟加密技术可以提高患者的隐私和舒适度，因为数据将通过安全通道无线传输。此外，硬币大小的自主能量采集传感器可以轻松部署，以监控需要最少维护的大面积区域。该项目中获得的结果、数据和模拟软件将在网站 https://www.eecs.utk.edu/people/faculty/dmateras/ 上存储至少五年。软件将在开源许可下发布，以促进结果的可复制性。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
