A first approach on an RGB image encryption

An RGB image encryption using diffusion process associated with chaotic map

“…Table 4 shows MSE of decrypted image with slight change in key. The MSE results obtained are better than the results of Kumar et al (2014) and Kumar (2013). The Peak Signal Noise Ratio (PSNR) of a given colour component is the ratio of the mean square difference of the component for the two images to the maximum mean square difference that can exist between any two images.…”

“…But the security of color images by the proposed cryptosystem is developed by affine hill cipher over S L n (F q ) [3] and M n (F q ) domains with Arnold transformation. The technique [4] provides security of RGB images by two stage random matrix affine cipher (RMAC) associated with discrete wavelet transform for each component of RGB image data. The security of the approach [4] is based on the keys and the arrangement of RMAC parameters.…”

“…The technique [4] provides security of RGB images by two stage random matrix affine cipher (RMAC) associated with discrete wavelet transform for each component of RGB image data. The security of the approach [4] is based on the keys and the arrangement of RMAC parameters. But in the proposed cryptosystem, the security of color images developed by each channel of color image with two phase affine hill cipher (TPAHC) over S L n (F q ) and M n (F q ) domains and Arnold transformation (AT), which is designed to ensure secure transmission of color image data.…”

Two Layers of Security for Color Video by Matrix Affine Cipher With Two-Dimensional Discrete Wavelet Transform

“…The technique in Ref. 1, the security of RGB image data is achieved via symmetric key cryptosystem. It implements novel approach for security of RGB image data using random matrix affine cipher (RMAC) and discrete wavelet transform for each channel of color images.…”
