The exploits of the structure of the DNA to realize the cryptographic systems is a new direction. The security of data transfer is an important factor for data transmission. Cryptography is one of the methods that ensures this constraint by techniques for sending data confidentially. Harnessing the benefits of DNA to secure information content makes cryptography more efficient. In this article, the authors propose a symmetric cryptography system based on DNA called Stegano-DNA- which operates under two main modules: scrambling and encryption. In its scrambling phase, Stegano-DNA eliminates the logical order of the letters in the clear text by the use of boxes of substitutions, and in its encryption phase, looks for the short sequence DNA in the chromosome sequence and memorizes only the number of positions needed to optimize the encryption time than when memorizing all positions.
