ABSTRACT
This chapter presents taxonomy of a Deoxyribonucleic Acid (DNA)-based security model, based on the categories. It discusses many existing DNA-based security models along with their advantages and disadvantages. The chapter presents the reasons for the proposed taxonomy. Many researchers have proposed many cryptographic schemes by using DNA computing, which can be categorized into two types: DNA-based data hiding schemes and DNA-based data encryption schemes. The existence of the DNA sequence is hidden in some other fake DNA sequences. C. T. Clelland et al. proposed the first method for data hiding, namely Hiding Messages in Microdots. Using a microdot, they developed a DNA-based steganographic technique to send secret data or messages. A DNA-based steganographic algorithm is used to hide a secret message. In 2011, M. R. Abbasy et al. proposed a Data Hiding Method using DNA for increasing the complexity. In 2013, M. Babaei proposed an efficient method for encryption, namely the Text and Image Encryption Method.
