计算的进步导致了对使用加密密钥和物理密钥合并的多因素身份验证的新兴需求。这封信提出了一种新颖的身份验证方法，该方法结合使用信号和天线激活序列，最重要的是，使用扰动的天线阵列几何形状。提出了影响物理特性的扰动天线阵列几何形状的可能自由度及其检测。讨论了多个有效授权阵列的信道估计。精度作为信噪比 (SNR) 和授权阵列数量的函数进行研究。据观察，所提出的认证方案可以在 10 dB SNR 下提供 1% 的误认证率，同时实现低于 1% 的漏认证率。
Advances in computing have resulted in an emerging need for multi-factor authentication using an amalgamation of cryptographic and physical keys. This letter presents a novel authentication approach using a combination of signal and antenna activation sequences, and most importantly, perturbed antenna array geometries. Possible degrees of freedom in perturbing antenna array geometries affected physical properties and their detection are presented. Channel estimation for the plurality of validly authorized arrays is discussed. Accuracy is investigated as a function of signal-to-noise ratio (SNR) and number of authorized arrays. It is observed that the proposed authentication scheme can provide 1% false authentication rate at 10 dB SNR, while it is achieving less than 1% missed authentication rates.
