Secure image encryption scheme based on fractals key with Fibonacci series and discrete dynamical system.

In this article, our aim is to design a new and efficient digital information confidentiality mechanism. We have offered an encryption scheme which is based on fractals and multiple chaotic iterative maps in order to add more confusion and diffusion capability. Due to randomness nature and unique repetitive pattern of fractal increases key space to hundreds of bits and enhance security level of proposed cryptosystem. The projected algorithm is authenticated by utilizing security performance analyses. The security performances elucidate that our suggested technique is quite competent for digital image encryption.
