Cryptanalysis and Improvement in a Plaintext-Related Image Encryption Scheme Based on Hyper Chaos
Recently, a plaintext-related image encryption scheme based on a hyper-chaotic system has been proposed by Li et al. In their encryption scheme, the permutation process is related to the sum of plaintext pixel values, and the diffusion process is related to the values of nine special positions in th...
