摘要

摘要: 單載波頻域均衡(SC-FDE)系統(tǒng)中，信道的頻域響應(yīng)可以作為隨機(jī)源來生成密鑰。為了提高密鑰容量，該文提出一種利用多徑瑞利信道的頻域響應(yīng)來生成密鑰的機(jī)制(CFR-Key)。首先研究了CFR-Key機(jī)制的原理和密鑰生成速率，通過互信息理論推導(dǎo)出了CFR-Key的密鑰容量；進(jìn)而研究了CFR-Key機(jī)制中算法的量化等級(jí)的影響因素，推導(dǎo)驗(yàn)證了量化等級(jí)的選擇只與信噪比有關(guān)，當(dāng)信噪比確定的情況下通過選擇最優(yōu)的量化等級(jí)可以得到最大的密鑰生成速率；與基于信道沖激響應(yīng)生成密鑰機(jī)制(CIR-Key)對(duì)比，證實(shí)了CFR-Key機(jī)制可大幅提高密鑰容量。

Abstract: A secret key generation scheme is proposed in a Single Carrier Frequency Domain Equalization system (SC-FDE). The scheme uses the Channel Frequency Response (CFR) to generate the secret keys, which is termed as CFR-Key. The principle of the CFR-Key scheme is introduced and formulate the secret key capacity is derived based on mutual information theory. The Signal-Noise Ratio (SNR) is proved that is the unique factor and affects the quantization levels. The optimum quantization levels is designed to achieve the best key generation rate when SNR is given. Simulation results show that comparing with the secret key generation scheme based on the Channel Impulse Response (CIR-Key), the proposed scheme can significantly improve the secret key capacity.
