摘　　要：为了提高光学图像的传输安全性,针对当前光学图像加密算法存在的缺陷,提出了一种基于单通道的光学图像加密算法。首先设计迭代图像复数模型以解决光学图像加密过程的复杂性,并引入混沌系统构造加密函数,减少光学图像的传输负载,然后通过混沌系统对光学图像进行单通道加密,防止出现"失真现象",最后对加密和解决性能进行测试和分析。测试结果表明,单通道加密算法可以获得十分理想的光学图像加密效果,解密质量好,具有广泛的应用前景。In order to improve the security of optical image transmission, aiming at the defects of current optical image encryption algorithms, an optical image encryption algorithm based on single channel is proposed in this paper. Firstly, the complexity of the current optical image encryption process is solved by designing the iterative image complex model, and the chaotic system is introduced to construct the encryption function and reduce the transmission load of the optical image, and secondly the chaotic system is used to single channel encryption the optical image, and the appear- ance of ＂distortion phenomenon＂ is prevented,and lastly, test and analyze the performance of encryption and decryp- tion. The results show that the proposed encryption algorithm can obtain very good image encryption effect and good de- cryption quality, so it has a broad application prospect.
