Data Encryption in Communication Using DNA Sequences

cryptography is a field which makes the transmitted message unreadable to unauthorised users. In this work we take inspiration from DNA encryption schemes and use of biological alphabets to manipulate information by employing the DNA sequence reaction to autonomously make a copy of its threads as an extended encryption key. Information is converted from plain text to several formats and then follows the stages of protein formation from DNA sequences to generate an extended key using chemical property and attributes to be used in encryption mechanism. This technique will enhance the security of the encryption mechanism by substitution, manipulation, and complexity. Furthermore this technique can be used in many applications of information and communication systems as well as adding more complexity to existing encryption algorithms.
