Abstract
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.
Highlights
Process of converting messages from plain text to cipher text is called cryptography
We propose chemical properties of the DNA sequences are used for key generation purposes, which will be autonomously generated for communications encryption
Most of the known algorithms for DNA encryption use secret codes from one-time-pads generated from DNA sequences as a secret key to encrypt data
Summary
Process of converting messages from plain text to cipher text is called cryptography. DNA based bimolecular cryptography design is a technique that uses the huge parallel processing capabilities of bio molecular computation which converts short messages from hexadecimal and ASCII forms and back to encrypt and decrypt the information. This has been used on different applications, but we consider using this technique to safeguard sensitive information with the addition of the key generation technique from the bio-molecular properties of the DNA sequences. We use chemical properties of the sequences as an indexing keys to authenticate the communications and hide information from exploitation techniques used by intruders specially frequency analysis based attacks. We take this into account to go through current security methods and encryption algorithms to propose a novel algorithm to enhance the security and complexity of an encryption mechanism
