Abstract EN
An image encryption algorithm based on improved piecewise linear chaotic map (MPWLCM) model was proposed.
The algorithm uses the MPWLCM to permute and diffuse plain image simultaneously.
Due to the sensitivity to initial key values, system parameters, and ergodicity in chaotic system, two pseudorandom sequences are designed and used in the processes of permutation and diffusion.
The order of processing pixels is not in accordance with the index of pixels, but it is from beginning or end alternately.
The cipher feedback was introduced in diffusion process.
Test results and security analysis show that not only the scheme can achieve good encryption results but also its key space is large enough to resist against brute attack.
