| Abstract: | In order to improve the security of infrared monitoring system and based on the frequency domain character of DFT,the data of DFT and Lorenz chaotic system has been processed. An infrared image encryption method in DFT frequency domain based on Lorenz chaotic system has been advanced in the paper. The experiment results show that the cipher image looks like noise and has good resistance property for exhaustive and clipping attack. So it resolves the security problem of high speed transmission of infrared image. |
