摘要：
A chaos based image encryption scheme with bit level operation and nonlinear chaotic map is proposed in this paper. The bit plane permutation and diffusion using bits from neighboring pixel and other two colour channels introduce confusion and diffusion within the colour components as well as between the colour components. Simulation results show that the security of the scheme is enhanced when compared with certain known existing schemes.
