基于Piecewise映射的安全密文域可逆信息隐藏算法
security reversible data hiding algorithm in encrypted domain based on Piecewise chaotic mapping
摘要
Abstract
Symmetric encryption is often used in reversible data hiding in encrypted domain(RDH-ED).However,it has been proved that it is difficult to resist ciphertext-only attack,chosen-plaintext attack or known-plaintext attack(KPA)under the existing conditions by using only stream cipher XOR,scrambling or a combination of the two methods.Therefore,in order to improve the security of RDH-ED,a secure RDH-ED algorithm based on Piecewise chaotic mapping is proposed.The plaintext image is divided into blocks and XOR in bit units.The Piecewise chaotic mapping conversion key is used to perform intra block bitplane scrambling on the XOR image,and inter block scrambling encryption on the image.The experimental results show that the key space of the algorithm is increased to 28Np×Np!×8!Np compared with the single encryption method on the basis of being visually imperceptible and achieve the uniform distribution of pixel values,and it can resist the existing various attack methods.The cracking rate under the recent KPA test is 0.006 7%,which can enhance the security of the image while retaining the appropriate embedding amount.At the same time,after the Piecewise mapping,the key communication traffic does not change,and the original image can be restored completely and reversibly.关键词
