THzID: A 1.6mm2 Package-Less Cryptographic Identification Tag with Backscattering and Beam-Steering at 260GHz

📋 论文概要

本文提出了一种基于260GHz太赫兹频段的无封装加密识别标签（THzID），采用背向散射和波束控制技术实现定向安全通信，面积仅1.6mm²。旨在解决小型化、低成本标签的识别问题及隐私保护问题。

💡 主要创新点

• 首次在太赫兹频段实现无封装标签，利用波束控制增强通信定向性以保护隐私。
• 集成加密功能与背向散射通信，在极小的芯片面积上完成安全识别。

Chandrakasan1, Ruonan Han1 Massachusetts Institute of Technology, Cambridge, MA Analog Devices, Boston, MA 3 Boston University, Boston, MA 1 2 Energy-autonomous wireless tags have been adopted in authentication and supply-chain management. At present, their size and cost, limited by packaging, prevent the tagging for small or inexpensive industrial/medical components. At the same time, pervasive electronic tagging raises serious privacy concerns related to inadvertent and malicious tracking of the tagged assets. In order to enable secure and ubiquitous asset tagging, fully passive particle-sized cryptographic chips without external packaging are highly desired. Recent prototypes [1-4] that aim to address this challenge face either size, energy, communication, or security limitations. [1] demonstrates a 9mm2 sensor node,
