摘　　要：为了提高光通信网安全,设计了基于动态密钥的光通信网络数据传输加密方法,首先设定光通信网络数据加密协,跟随数据传输时段,对标数据的排放序列,促使动态密钥不间断更新,自动密钥协商下核对数据传输内容,对照加密和解密全过程,实现光通信网络数据的加密传输,完成方法设计。实验结果表明:本方法在有障碍与无障碍情况下的密钥的生成时间最长分别为0.6 s、0.2 s,且在有障碍与无障碍情况下的窃听占比均保持在10%左右;能够削减数据的窃取成功率。In order to improve the security of optical communication network,an optical communication network data transmission encryption method based on dynamic key is designed.Firstly,set the optical communication network data encryption protocol,follow the data transmission period,and check the emission sequence of standard data,so that the dynamic key can be updated continuously.Under the automatic key negotiation,check the data transmission content,and compare the whole process of encryption and decryption to achieve the encrypted transmission of optical communication network data,and complete the method design.The experimental results show that the longest key generation time of the method in this paper is 0.6 s and 0.2 s respectively and accessibility is 0.6 s and 0.2 s,respectively,and the proportion of eavesdropping in both obstacle and accessibility is maintained at about 10%.Ii is able to cut data theft success rates.
