RGB Image Encryption and Decryption Using Discrete Wavelet Transformation

EasyChair Preprint no. 7341

12 pagesDate: January 18, 2022


To increase confidentiality of image,we propose an RGB image encryption and decryption using two stage random matrix affine cipher related to discrete wavelet transformation. In our proposed approach, color image encryption associated with DWT is immune the known-plaintext attack and chosen cipher-text attack, etc. This proposed approach is suitable for secure transmission of huge size images that ensure the total number of possible keys (key space of the whole cryptosystem) for attackers to decrypt correct (or wrong) images depending upon the right (or wrong) arrangement of parameters is very large.

Keyphrases: Discrete Wavelet Transformation, Image encryption and decryption, MSE, PSNR, RGB color image
