Research on security of optical CDMA system

  • 摘要: 简要介绍了OCDMA系统的原理,分析了码型和码容量、地址序列的扩频作用对OCDMA安全性的影响,结合完全无差错探测几率给出完全探测到正确地址码所需探测次数的期望值,并以此重点分析了码字探测对OCDMA安全性的影响,比较分析了OCDMA技术与现代光纤保密通信技术的关系,给出了增加OCDMA系统安全性而采取的一些措施。
    Abstract: The OCDMA system is briefly introduced. The code pattern and code capacity, the role of sequence spread spectrum to the security of OCDMA are analyzed, the expectations of the frequency of the correct address code detection is given with complete error-free detection probability and the address code detection to the security of OCDMA is analyzed. The relationship between OCDMA technology and modern fiber-optic secure communication technology is compared. Some measures to increase security of the OCDMA system are put forward.
