摘要

为了在毫米波（mmWave）多输入多输出（MIMO）通信系统中实现高效的物理层安全密钥协商，基于毫米波MIMO多维信道参数特性，提出了一种基于多维优势提取（AD）的密钥协商方法。将毫米波MIMO信道建模为跨空-时-频域的高维张量，合法通信双方采用张量唯一性分解方法，通过一次双向信道估计同时获取幅度、角度、时延等多个信道参数估计值作为优势提取的公共随机性源进行密钥协商，提高了密钥协商效率。在此基础上，综合几何和统计特性分析，建立合法信道与窃听信道参数间的相关性模型，研究了所提方法在不同信道相关场景下的密钥率性能，分析了不同因素对密钥率的影响。

Abstract

To achieve efficient physical layer secure secret key agreement in millimeter wave (mmWave) multiple input multiple output (MIMO) communication systems

a key agreement method was proposed based on multi-dimensional advantage distillation (AD) exploiting the multi-dimensional characteristics of mmWave MIMO channel parameters. The mmWave MIMO channel was modeled as a high-dimensional tensor spanning the space

time

and frequency domains. The legitimate communication parties alternately sent pilot symbols

based on the uniqueness property of tensor decomposition

simultaneously acquired estimates of multiple channel parameters

i.e. amplitude

angle

and delay

in a single shot. The legitimate communication parties used the common information contained in the estimates of the multiple channel parameters as the source of common randomness for advantage distillation

thus significantly improving the overall efficiency of key agreement. Further

a correlation model between the legitimate and eavesdropping channel parameters was derived through a joint geometric and statistical analysis of the channels. Simulation studies were conducted to evaluate the key rate performance of the proposed method under different channel correlation scenarios and to investigate the impact of different factors on the key rate.
