摘要
为提高红外监控系统安全性,在详细分析红外图像DFT特征的基础上,通过对DFT数据和Lorenz混沌系统数据进行科学处理,实现了基于Lorenz混沌系统的红外图像频域加密,并使加密效果可视化。实验结果表明,该算法能够抵抗穷举攻击和裁剪攻击,具有较快的运算速度,有效解决了红外图像高速网络传输的安全性难题。
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.
