均匀散射环境中物理层安全密钥容量分析
Analysis of physical layer secret key capacity in the uniform scattering environment
摘要
Abstract
Physical layer secret key capacity was affected by time difference of channel sounding, mobility of terminals, and additive noise. Effects on the physical layer secret key capacity were quantitatively analyzed in the uniform scattering environment. Based on the time domain statistical characteristics of narrow band wireless channel parameters with noise, a closed-form solution to physical layer secret key capacity in the time domain was derived. Afterwards, simulations in the uniform and non-uniform scattering environment were carried out to demonstrate its validity and applicability, re-spectively.关键词
