摘要
随着信息网络化飞速发展,图像网络交互在诸多领域得到应用,尤其某些图像信息涉及个人隐私和国家安全,必须采取秘密传输的方式,因此图像加密的安全问题备受人们关注。文章提出了基于创新性的图像预处理、二维到三维图像信息变换的图像加密算法的加密原理、优势和最新进展。实验结果表明该成果对图像加密算法的改进、新算法的研究以及在实际工程中对算法的选取具有重要意义。
With the rapid development of information network, image interactive network has been applied in many fields, es- pecially some image information involves individual privacy and national security, must take the secret transmission mode, so the security problems of image encryption is paid more attention. This paper presents an innovative encryption principle, advan- tage and the latest progress based on image preprocessing, image encryption algorithm based on two-dimensional to three-di- mensional image information transform. The experimental results show that the image encryption algorithm on the improved al- gorithm,the selection of the algorithm, engineering significance is important.
