DNA Based Cryptography and Stegnography

The most common and widely used technique in the communication security and computer security fields is cryptography. Cryptography includes converting some data to incomprehensible format so that a non-intended recipient cannot determine its intended meaning. In this project, a binary form of data, such as plaintext message transformed into sequences of DNA nucleotides. The proposed method is a two-step procedure. First it converts the text messages to a DNA format, subsequently the nucleotides are passing through a Playfair Encryption process based on amino acids structure and in the second phase hide these message in a reference DNA sequence using 3:1 hiding rule.
