Eihab Bashier, Ghaidaa Ahmed, Hussam-aldeen Othman, Rayan Shappo . Hiding Secret Messages using Artificial DNA Sequences Generated by Integer Chaotic Maps. International Journal of Computer Applications. 70, 15 ( May 2013), 1-5. DOI=10.5120/12035-7970
Almost all the existing DNA steganography techniques are based on DNA sequences from the existing databases such as the Gen- Bank. With the current available computational powers, bruteforce attacks on those DNA data sequences can easily be carried out. In this paper, the technique of generating artificial DNA sequences using chaotic maps running on the domain of integer numbers is introduced. Then, two steganography algorithms for hiding a cipher message in artificial DNA sequences, before sending it to the other party are developped; where the natural techniques by which the genes are hidden, accessed in the DNA and translated are simulated in this paper. The purpose of using this type of chaotic maps is to allow the compatibility between devices with different architictures, such that the extraction and decryption of the hidden message can be carried out correctly. The first algorithm has low computational requirements but vulnerable to statistical attacks when the cipher message is divided into large number of sub-messages. This issue is dealt with in the second algorithm.
