摘要
将图像的加密和压缩结合在一起同步完成可以带来设计上的灵活和计算上的简化,同时也可以更好地保证安全性,为图像信息的安全高效存储和传输做出保障。基于CALIC良好的压缩效率,本文研究并设计了面向CALIC的图像加密算法。根据CALIC编码原理,算法实现在CALIC编码过程中的加密,主要包括GAP预测值的加密、最终残差的加密、明文像素的加密、熵编码码流的加密。实验结果表明面向CALIC的图像加密算法在压缩性能上取得较好效果的同时增加了安全性。
Image encryption combined with image compression synchronously can result in the design flexibility and computational simplification.Moreover,encryption and compression are mixed together to ensure better security,and ensure secure and efficient image information storage and transmission.In terms of good compression performance of CALIC,image encryption scheme for C.ALIC is studied.Based on CALIC coding principle,the algorithm performs encryption in CALIC coding process,including encryption of gradient-adjusted prediction,encryption of final residual,encryption of two lines of pixels needed by prediction mode,and encryption of entropy coding bit stream.The experimental results show that the image encyption scheme for CALIC has better compression p erformance and security.
