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.

Arraymetrics:通过混沌天线阵列几何进行身份验证

计算的进步导致对使用加密和物理密钥的融合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,该方法结合了信号和天线激活序列,以及最重要的是干扰了天线阵列的几何形状。提出了扰动天线阵列几何形状影响物理特性的可能自由度及其检测方法。讨论了多个有效授权阵列的信道估计。根据信噪比(SNR)和授权阵列的数量来研究准确性。可以看出,所提出的认证方案可以在10 dB SNR的情况下提供1%的伪认证率,而实现的伪认证率不到1%。
