We propose an improved image encryption algorithm based on hyper chaotic system and permutation-diffusion structure. In the permutation process, the algorithm introduces plain-text feedback mechanism that makes the permutation effect not only associated with the chaotic sequences, but also related to plain-text. And in the diffusion process, the algorithm introduces both cipher-text and plain-text feedback mechanisms to diffuse the permuted image. All of these methods make the mapping-relationship between cipher-text and plain-text as well as secret keys more complex. At last, the security analysis such as key space analysis, histograms, correlation coefficients, information entropy, key sensitivity analysis, plaintext sensitivity, speed analysis. We also perform series evaluation experiments, experimental results show that the proposed image encryption scheme is of very good performance on security and reliability, with high potential to be adopted for the secure image communication applications. |
