An adaptive image encryption scheme based on bit-level permutation
Ping Wang, Jin Qiu · 2019
The paper describes an adaptive image encryption scheme. In the proposed encryption scheme, the chaotic map is used to design the plaintext dependent bit-level permutation. The plain image is firstly divided into 8 bit panels and then arranged into two groups. The permutation is performed on each group based on the feature of the other group. After that, the keystream is employed to mask the permutated image to get the cipher-image. The different types of experiments have been conducted. The experimental results and security analysis demonstrate that the proposed encryption scheme is efficient and highly secure.
