摘要

摘要: 利用无线信道参数提取物理层安全密钥时，密钥容量受加性噪声、信道测量时差、终端移动速度、采样周期和采样点数等因素影响。针对这一问题，该文在均匀散射环境中利用单输入单输出无线信道定量分析密钥容量，推导了密钥容量的闭式解以确定最佳采样周期的约束条件。仿真分析表明该结论同样适用于非均匀散射环境，同时验证将物理层密钥提取技术应用于无线通信系统的可行性。

Abstract: Physical layer secret key capacity is affected by such factors as additive noise, the time difference of channel sampling, terminals moving speed, sampling period, and the number of samples, whose effects on the physical layer secret key capacity are analyzed quantitatively using the single-input single-output wireless channel over the uniform scattering environment. Specifically, a closed-form solution to the secret key capacity is derived to determine the constraints on the optimal sampling period. Analysis and simulation results reveal that the results can also be applied to the nonuniform scattering environment. Furthermore, the feasibility to utilize the physical layer secret key extraction techniques in the mobile communication systems is verified.
