Abstract

Recently, DNA sequences and hyperchaotic sequence are jointly used for building secure and efficient image encryption model. However, the state-of-art model are not efficient (robust) against noise and cropping attack. Since, in existing model most digits of each pixel are not altered. For enhancing security for encrypting high dimensional images, this work use both hyperchaotic and DNA sequence. Firstly, pseudorandom sequence is generated using hyperchaotic system. This is done to use hyperchaotic sequence for nearly entire process of the encryption where intensity parameters of a high dimensional image are transformed to a serial binary digit stream. Then, this stream of bits is scrambled using hyperchaotic sequence. DNA complementation and algebraic function are conducted among the DNA and the hyperchaotic sequences to attain efficient and robust image encryption performance. Experimental outcome shows proposed image encryption model attain superior performance than stat-of-art model in terms of robustness against cropping attack and noise.
