Abstract -
A novel self-adaptive color image
encryption scheme with exchange strategy is
proposed. The 2D skew tent map is used to generate
chaotic sequences to exchange the 4 higher bits part
and the 4 lower bits part at half-pixel level with
respect to the red, green, blue color components of
the plain-image. The resulted three base color
components are combined horizontally and
encrypted simultaneously then to reduce the
correlations among the three base color
components. Moreover, self-adaptive diffusion
process is adopted to encrypt the red, green, blue
components in a cross way. The security and
performance of the proposed image encryption
scheme have been analyzed. All the experimental
results show that the proposed scheme is secure and
effective for practical application.
