Background & Objective:
Digital multimedia exchange between different mobile communication
devices has increased rapidly with the invention of the high-speed data services like
LTE-A, LTE, and WiMAX. However, there are always certain security risks associated with the use
of wireless communication technologies.
Methods:
To protect the digital images against cryptographic attacks different image encryption algorithms
are being employed in the wireless communication networks. These algorithms use comparatively
less key spaces and accordingly offer inadequate security. The proposed algorithm described
in this paper based on Rubik’s cube principle because of its high confusion and diffusion
properties, Arnold function having effective scrambling power, blocking cipher with block encryption
and permutation powers. The main strength of the proposed algorithm lies in the large key spaces
and the combination of different high power encryption techniques at each stage of algorithm. The
different operations employed on the image are with four security keys of different key spaces at
multiple stages of the algorithm.
Results & Conclusion:
Finally, the effectiveness and the security analysis results shows that the proposed
image encryption algorithm attains high encryption and security capabilities along with high
resistance against cryptanalytic attacks, differential attacks and statistical attacks.
