In order to improve the secure transmission capability of data in fiber optic sensing networks,a secure data import method based on information leakage encryption transmission is proposed for fiber optic sensing networks.The discrete chaotic time series synchronous modulation method is used to realize the modulation and coding processing in the process of importing the transmission data of the optical fiber sensor network.According to the chaotic random coding characteristics,the synchronous output stability adjustment and autonomous random coding in the process of transmitting data of the optical fiber sensor network are realized,and the encryption key for suppressing the information transmission leakage of the optical fiber sensor network is constructed,The information leakage encryption retransmission during the data import process of the optical fiber sensor network transmission is realized through Logistic mapping.According to the mixed sensitive key representation and Arithmetic coding of the optical fiber sensor network transmission data,the information leakage control and data security import are realized.The simulation test results show that the encryption performance of the imported data transmitted by the proposed method is good.The recognition rate of the encrypted bit sequence of the transmitted data transmitted by the optical fiber sensor network is not less than 98%,the highest bit error rate is only 2.7∗10-9%,the anti-leakage ability reaches 0.970,and the integrity of the imported data reaches 0.996.It shows that the method has strong encryption effect and anti-leakage ability,and realizes the safe import and encrypted transmission of data.
