Design of laser network communication encryption, improve communication privacy. According to the low cyclic shift key decoding speed, strong sensitivity problem, put forward based on piecewise linear key check the chaotic laser network communication encryption technology. First for floating point data of chaotic laser network communication arithmetic coding to build encryption scheme diagram, using laser chaos mapping skew tent to network communication source key design parameters, and then use the piecewise linear calibration method for source parameter keys to chaos encoding and decoding design, optimized encryption technology. Finally USES to enerypt data simulation performance test, the results show that using the method of laser chaos encryption has good reliability of network communi- cation, reduce the risk of crack, improved the confidentiality of the data transmission oerformance.
