EAGER: SARE: Collaborative: Low Energy Secure Wireless Transceiversfor IoT Trusted Communications

低能量无线通信作为维护网络中用户之间的连接的首选方法正日益流行。建立无线通信链路的安全和信任对于维护用户的安全和隐私至关重要。用于创建安全可靠的数据通信链路的现有解决方案主要集中于在后端执行的复杂的能量密集型数字编码。虽然这种方法很有效，但与无线链路的低能耗特性本质上是不一致的。该项目旨在通过开发可在射频前端实施的低能量射频(RF)和模拟安全功能来应对这一挑战。从这项研究中获得的新知识将为低功耗、低延迟的可信无线通信奠定基础。除了消费电子产品，低能量安全无线电收发机的成功开发将对各种应用和行业产生深远影响，在这些应用和行业中，安全和可信的电磁频谱访问至关重要。除了技术影响，该项目还广泛地造福于社会。通过为通过物联网(IoT)连接的低能耗设备带来急需的低成本安全，这项研究将对改善日益在日常生活中使用这些设备的弱势社会经济群体的人们的生活和隐私产生深远的积极影响。本项目的目标是通过在射频和模拟域使用安全特性来创建一个新的低能耗、低延迟、安全和可信的无线通信收发信机框架，消除对耗能的实时数字后端加密的需要。该研究利用了许多低能耗无线连接应用的实时特性，以权衡在数字后端完成的耗能大的逐位数字加密与在射频前端实施的低能耗射频和模拟安全功能。通过在模拟域中对调制波形进行模糊处理，可以设想安全的无线链路。一旦建立了安全的无线链路/通道，就会使用唯一的设备属性在模拟域中应用设备身份验证。该项目的智力优势涉及安全和身份验证两个重要领域。(I)研究提供了一种整体的系统级和电路级方法，该方法使用RF/模拟技术来创建低能耗、低延迟、可信的无线通信链路，而对数字后端的依赖程度最低。(Ii)它创建了一个两步RF/模拟混淆和加密系统，该系统将通道安全与设备身份验证相结合，以创建受模拟启发的端到端安全无线通信链路。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Low-energy wireless communication is gaining currency as the preferred method to maintain connectivity between users in a network. Establishing the security and trust in the wireless communication link is vital to maintaining the security and privacy of users. Existing solutions to create a secure and trustworthy data communication link have primarily focused on complicated energy-intensive digital encoding performed in the backend. While effective, this approach is inherently inconsistent with the low-energy nature of the wireless link. This project aims to address this challenge by developing low-energy radio frequency (RF) and analog security features that can be implemented in the RF front-end. The new knowledge gained from this research will form the foundation for low-power low-latency trusted wireless communications. Besides consumer electronics, the successful development of low-energy secure radio transceivers will have profound impact on various applications and industries, where secure and trusted access to the electromagnetic spectrum is paramount. In addition to the technical impact, the project broadly benefits the society. By bringing much-needed low-cost security to low-energy devices connected through the internet of things (IoT), this research will have a far-reaching positive impact in enhancing the lives and privacy of people from disadvantageous social economic groups who increasingly use these devices in their daily life.The objective of this project is to create a new framework for low-energy low-latency secure and trustworthy wireless communication transceivers by employing security features in the RF and analog domain that obviate the need for energy-hungry real-time digital backend encryption. The research takes advantage of the real-time nature of many low-energy wireless connectivity applications to trade off energy-heavy bit-by-bit digital encryption done in the digital backend with low-energy RF and analog security features implemented in the RF front-end. By obfuscating the modulated waveform in the analog domain, a secure wireless link is envisaged. Once a secure wireless link/channel is established, device authentication is applied in the analog domain using unique device attributes. The intellectual merits of this project involve two important areas of security and authentication. (i) The research offers a holistic system- and circuit-level approach that uses RF/analog techniques to create low-energy low-latency trusted wireless communication links with minimal dependence on the digital backend. (ii) It creates a two-step RF/analog obfuscation and encryption system that combines the channel security with device authentication to create an analog-inspired end-to-end secure wireless communication link.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.
