“…The correlation between the adjacent pixels of the encrypted images optimal and is close to zero. It is found that the obtained values are better than the methods in [10,15,20,21], comparable with those methods in [13,14,23] and slightly lesser than the method in [1]. The pictorial view of relationship between the adjacent pixels in horizontal, vertical, and diagonal directions in the original and encrypted Lena images are shown in Figure 8.…”

Information security has become an important issue for data storage and transmission due to growth of communication development and exchange of sensitive information through Internet. The services like confidentiality, integrity, and digital signature are required to protect data against unauthorized modification and misuse by anti social elements. Image encryption is widely used in multimedia, medical imaging, telemedicine and military communications to provide confidentiality service. A novel and simple image encryption method using Z-Order (ZO) curve based scan pattern and random number is proposed in this paper. The proposed method resists the statistical and differential attacks. The method provides optimal entropy value and assures security from the additive noise and cropping attacks.

“…In this paper, we need only to refer to the GENE BANK once for key generation in comparison with indexed based method et al [4], where every time the database is required to be referenced for DNA sequence. There are total 8 kinds of the DNA coding to meet the complementary rule, and there are altogether 6 kinds of legal complementary rules to be applied, which make the algorithm more secure.…”

“…Various operations performed on DNA include synthesis, insertion, truncation, deletion, transformation, ligation and polymerase chain reaction etc. Qiang Zhang et.al [4] proposed an encryption method that used DNA subsequence operations such as truncation, deletion and transformation operation combined with chaos system to scramble the location and value of image pixel. Encryption method proposed by Nirmalya Kar et al [5] used DNA sequencing along with cryptographic algorithm to generate the cipher text similar with the biological structure of the DNA Strands.…”

In recent years, various DNA based cryptographic algorithms have been suggested to develop secure image encryption techniques but still many of them have low computing security as they have low avalanche effect and require to send long key . In this regard, this paper proposes a new method of image encryption based on DNA computation technology. The original image is encrypted using DNA computation and DNA complementary rule. First, a secret key is generated using a DNA sequence and modular arithmetic operations. Then each pixel value of the image undergoes the encryption process using the key and DNA computation methods. The researcher prove the validity of the algorithm through simulation and the theoretical analysis on the parameters such as sensitivity to plaintext, key sensitivity, histogram analysis, correlation analysis including bio-security and math security. Further, the algorithm has huge key space generated using key expansion algorithm while keeping the original key sequence small. It is shown the algorithm has achieved the satisfactory computing security level in the encryption security estimating system.

“…The ancient Greeks also used to write in tablets and cover them by wax. Nowadays the steganography methods have developed a lot using digital cover medium carrier such as videos, audios, images [5], [15], text files, TCP/IP headers, documents and DNA steganography [1]. The DNA steganography explores and exploits DNA molecular techniques to hide information.…”

Almost all the existing DNA steganography techniques are based on DNA sequences from the existing databases such as the GenBank. 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. General Terms:DNA steganography, Chaotic maps
