AI 中文摘要
本文提出了去噪自编码器（DAE）辅助的密钥生成（SKG），抑制了因无线信道测量引起的信道噪声互易性缺陷，显著提高了可靠性和效率。具体而言，DAE能捕捉输入分布的内在结构，重建原始数据结构并去除加性噪声同时保留信号基本结构。分析表明，所提SKG方案在密钥不一致率、密钥容量和生成密钥的随机性方面比传统方案性能更高。
英文摘要
In this paper, we propose denoising autoencoder (DAE)-assisted secret key generation (SKG), where channel noise reciprocity imperfections induced due to wireless channel measurements are suppressed, hence significantly enhancing the reliability and efficiency. More specifically, the DAE is capable of capturing the intrinsic structure of input distributions, reconstructing the original data structure, and removing additive noise while preserving the essential structure of signals. In our analysis, it is demonstrated that the proposed SKG scheme exhibits higher performance than the conventional schemes in terms of key disagreement rate (KDR), secret key capacity (SKC), and randomness of the generated keys.
