摘要:
图像信息的传输需要通过压缩和加密来减少冗余并阻止非授权者的访问.关于图像压缩的研究由来已久,各种压缩算法和理论层出不穷,而加密压缩仍有相当大的发展空间.为此,针对目前常见的已知明文攻击等黑客攻击方式,在研究Logistic混沌加密技术和基于混沌置乱的分量融合图像加密压缩方法的基础上,提出了一种可逆的融合算法.该算法将提取到的彩色图像颜色分量分别进行DCT变换而后融合,将压缩和加密过程同时进行,显著提高了压缩算法的安全性.前期研究表明,即便所提出的方法已经可以满足正常的加密要求,但一旦泄露了部分明文,安全性便立刻降低.为了提高对已知明文的安全性,在进行完加密压缩过程之后,又使用Logistic混沌映射置乱作为二次加密.实验结果表明,在保证较好压缩性能的条件下,所提出的方法成功通过了已知明文攻击等黑客攻击方式的测试.
Abstract:
 The transmission of image information needs to be compressed and encrypted to reduce redundancy and prevent unauthorized accessing.Image compression has been investigated for a long time,so various compressed algorithms and theories have emerged in an endless stream,and there is still space for improvement in the field of encryption compression.In view of the known-plaintext attacks and other hacker attacks,on the basis of studying on Logistic chaos encryption and mage encryption and compression method based on chaos scrambling,an inverse fusion method is proposed.It fuses the color component extracted in RGB image after it is conducted Discrete Cosine Transform (DCT),which carries out compression and encryption meanwhile,improving its security significantly.Although it can meet the requirements of normal encryption,previous investigations have shown that once leaked part of plaintext,its safety must be reduced.In order to improve the security against known-plaintext attacks,Logistic chaos scrambling has been employed as the second encryption after encrypted and compressed.The experimental results show that it can successfully resist the known-plaintext attacks and hacker attack test with good compression performance.
