中文摘要:
      目的 为了避免传统加密算法直接将图像信息作为明文加密及加密图像含有明文图像信息而带来被破解的风险,提出一种将伪明文图像加密嵌入宿主图像传输的强鲁棒性信息加密技术。方法 首先对明文图像彩色QR码和伪明文图像进行初步加密,然后通过加性原则构造出两者之间的映射矩阵,最后基于小波变换和奇异值分解将加密后的伪图像嵌入到载体图像中。结果 仿真结果表明,该算法具有较高的安全性及强大的抗攻击能力。结论 算法通过将QR码作为明文图像建立与伪图像之间的关系,并将伪图像加密嵌入宿主图像传输,不仅有效地避免了明文被破解的风险,还具有较强的抗噪声、压缩、裁剪和旋转等恶意攻击能力,表明该加密算法具有良好的安全性和稳健性。
英文摘要:
      The work aims to put forward an information encryption technology with strong robustness by embedding pseudo plaintext image into host image transmission, in order to avoid the risk of being cracked brought by the traditional algorithm directly encrypting the image information as plaintext and the encrypted image with plaintext image information. First of all, preliminary encryption of plaintext image color QR code and pseudo plaintext image should be done, then the mapping matrix between two images by addition principle was constructed, and finally the encrypted pseudo image was embedded into the carrier image based on wavelet transform and singular value decomposition. Through establishing the relationship between the QR code (as plaintext image) and the pseudo image and embedding pseudo image into host image transmission, the algorithm not only effectively avoids the risk of cracked plaintext, but also has a strong ability to resist noise, compression, clipping, rotation and other malicious attacks, which shows that the encryption algorithm is of good security and robustness.
