Due to some inherent features of image such as bulk data capacity and high correlation
among pixels, image encryption is somehow different from text encryption; so,
traditional algorithms are not suitable for image encryption. The parameters and initial
conditions of the chaotic system are derived using a 256 bit-long external secret key by
applying some algebraic transformations to the key. The DNA sequence image matrix is
obtained by encoding the original image. Also, XOR and XNOR operations are
presented in this paper. We use the chaotic sequences to encrypt the elements from
DNA sequence image matrix in only three rounds of encryption. The algorithm employs
the image data in order to increase the resistance of the cryptosystem against differential
attacks. Experimental results and performance analysis prove the viability of the new
cryptosystem based on privacy, integrity, and authenticity.
