摘　　要：传统的数据加密方法,加密后图像的灰度值分布不均,导致关键信息外泄,因此对舰船监控数据提出嵌入式的加密方法。该方法利用混沌系统,增强数据序列的随机性;根据变换函数,置乱监控数据的位置信息;使用嵌入式系统代换明文字节,实现端到端的监控数据加密。实验结果表明,与传统加密方法相比,所提出加密方法加密后的监控数据灰度值分布均匀,隐藏了全部监控信息,加密效果更显著。The traditional data encryption method has uneven distribution of the gray value of the encrypted image,which leads to the leakage of key information. Therefore, an embedded encryption method is proposed for ship monitoring data. This method uses a chaotic system to enhance the randomness of the data sequence;scrambles the position information of the monitoring data according to the transformation function;uses the embedded system to replace the plaintext bytes to achieve end-to-end monitoring data encryption. The experimental results show that compared with the traditional encryption method, the proposed encryption method has even distribution of the gray value of the encrypted monitoring data, hides all the monitoring information, and has a more significant encryption effect.
