Deoxyribo Nucleic Acid (DNA) computing is a new method of simulating the bimolecular structure of DNA and computing by means of molecular biology. DNA cryptography is a new field which has been explored worldwide. The concept of using DNA computing in the fields of cryptography and steganography has been identified as a possible technology, which may bring forward a new hope for unbreakable alg...

To solve the problem of low secret space and security some image schemes, a novel 4D chaotic system is derived in this paper. Compared with other similar systems, new only has one equilibrium point can exhibit hyperchaotic characteristics, under parameter space. The better dynamic characters represented by calculation Lyapunov exponents, phase planes, visual 0–1 test diagram. In study, encrypti...

Similarity search of DNA sequences is a fundamental problem in the bioinformatics, serving as basis for many other problems. In this, calculation similarity value between most important, with Edit distance (ED) commonly used due to its high accuracy, but slow speed. With advantage transforming original into numerical vector form that retaining unique features based on properties. The processing...
