摘　　要：针对目前图像加密技术效率不高或安全性较弱的问题,在对混合图元加密基本原理阐述的基础上,提出了一种混合图元加密系统,建立了系统的数学模型和结构模型,并详细分析了系统的加密效率和安全性。从理论上对混合图元加密算法进行了较为深入的探讨。最后,对系统研究成果进行了概括,对尚待解决的问题进行了描述和展望。In view of the lower encryption efficiency or the weaker security of current image encryption technology, and on the basis of the encryption principle of mixed image element （MIE）, a MIE encryption system is proposed in this paper. The mathematical model and structure model of this system are also established. And the encryption efficiency and security analysis of this system is analyzed in detail in this paper. In terms of theory, the MIE encryption algorithm is discussed in depth. Finally, the achievements of this system are generalized, and the unsolved issues and outlook described.
