A Novel Two Layer Encryption Algorithm Using One-Time Pad and DNA Cryptography

Abstract

The need of encryption cannot be underestimated in today’s time. From a travel ticket to a movie ticket, almost everything of need is easily available. This comes with the cost of sharing important information, which if gets into wrong hand, will cause havoc. The aim of this work is to secure the data by fusing the extracts of one-time pad (OTP) and DNA cryptography. In the first level, a symmetric-key algorithm of OTP has been used to make the text secure which is a very random technique. In the next level, conventional DNA cryptographic techniques with few variations have been used. The target of implementation would be the storing and passing of vital information of customers like the debit/credit card details including the CVV code or the virtual passcode. Using DNA cryptography, large amount of storage can be made in the server with an efficient speed and power.
