入侵信号分析和识别有利于提高光纤通系统的安全性,而单一时域特征或频域特征无法保证光纤通信系统的安全要求。为了提高光纤通系统的安全性,对入侵号进行分析,设计了基于时域特征和频域特征的光纤通信系统入侵信号识别模型。首先采集光纤通系统的入侵信号,并分别从信号中提取时域与频域特征,然后根据特征建立光纤安全系统入侵识别模型,最后采用具体数据对其性能进行分析,结果表明,本文方法可以提高光纤安全系统入侵信号的识别率,能够保证光纤通信系统的正常工作。
Analysis and identification of intrusion signals help to improve the security of fiber-optic systems. However, single time-domain or frequency-domain features can not guarantee the security requirements of optical fiber communication systems. In order to improve the security of the fiber-optic system, the intrusion number is analyzed, and the intrusion signal identification model of the optical fiber communication system based on the time domain feature and the frequency domain feature is designed. Firstly, the intrusion signals of fiber-optic system are collected, and the time-domain and frequency-domain features are extracted respectively from the signals. Then, the fiber-optic security system intrusion identification model is established based on the characteristics. Finally, the performance of the system is analyzed with the specific data. The results show that the proposed method can improve Optical fiber security system intrusion signal recognition rate, to ensure the normal operation of the optical fiber communication system.
