摘要/Abstract

摘要： 传统基于接收信号强度的物理层密钥生成方案在窃听者靠近合法方时，合法方的密钥易被窃听者获取.针对该问题，在分析密钥误比特率的基础上，提出一种基于信号传播特性的物理层密钥生成方案.方案根据接收信号强度的实测样本估计大尺度衰落模型，提取出多径效应影响下的小尺度参数量化生成密钥.实验结果表明相比于传统方案，本方案在室内环境窃听距离大于0.6倍波长以后，窃听方密钥误比特率大于0.48；在室外环境窃听距离大于1倍波长后窃听方密钥误比特率为0.47，实现了安全可靠的物理层密钥生成.

Abstract: The existing physical layer secret key generation scheme is not sufficiently secure when the eavesdropper keeps close to the legitimate user to get the correlated channel characteristics.To solve the problem,this paper analyzes the secret key bit error rate and proposes a physical layer secret key generation scheme based on signal propagation characteristics.We calculate the large scale fading model which parameters is fitted by the measured sample,in order to get the small scale parameter of received signal strength indication under the effect of multipath fading to quantify into binary secret bit.The experimental results show that compared with the traditional scheme, in the indoor environment,after eavesdropping distance is greater than 0.6 wavelength,the eavesdropper key bit error rate is greater than 0.48.And in the outdoor environment,after the eavesdropping distance is greater than 1 wavelength,the eavesdropper key bit error rate is 0.47. Secure and reliable physical layer secret key generation is achieved.

Key words: physical layer security, secret key generation, signal propagation characteristics, received signal strength indicator (RSSI), secret key bit error rate
