Abstract

In this letter, a multi-dimensional dual-frequency physical layer cross-domain fusion secure distribution scheme is proposed. The scheme achieves physical isolation by using different frequencies to transmit encrypted data and key data within the W-band. The encrypted data is modulated using 16 quadrature amplitude modulation (QAM) to ensure information capacity, while the key is modulated using quadrature phase shift keying (QPSK) and interpolated to ensure reliable transmission. The overall system supports a data transmission rate of 20 Gb/s. Experimental results demonstrate that the encrypted data and the key can be transmitted and received simultaneously without crosstalk between them. This scheme can effectively prevent against brute attacks with the expanded key space of

$10^{119}$

, the bit error rate (BER) of the illegal user is above 0.4, while leveraging the W-band high-speed, high-capacity transmission to enhance communication system efficiency and performance, thereby enabling the development of secure communication.

多维双频物理层跨域融合安全分发方案

本文提出了一种多维双频物理层跨域融合安全分发方案。该方案通过在w频段内使用不同的频率传输加密数据和密钥数据来实现物理隔离。加密数据采用16正交调幅（QAM）调制以保证信息容量，密钥采用正交相移键控（QPSK）调制并内插，保证传输可靠。整个系统支持20gb /s的数据传输速率。实验结果表明，加密后的数据和密钥可以同时传输和接收，互不产生串扰。该方案可以有效防止暴力攻击，密钥空间扩展到$10^{119}$，非法用户的误码率（BER）在0.4以上，同时利用w波段的高速、大容量传输，提高通信系统的效率和性能，从而实现安全通信的发展。

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
