An improved substitution method for data encryption using DNA sequence and CDMB

Abstract

Cryptography provides the solution in fields such as banking services, digital certificate, digital signature, message and image encryption etc. In this paper, we propose an improved data encryption approach based on the Deoxyribonucleic acid that exploits two different techniques: Substitution technique and Central Dogma of Molecular Biology. It transforms the message into protein (cipher text) using various complementary rules. Deoxyribonucleic acid provides robust DNA sequence for the substitution technique from approximately 163 million huge DNA database, where Central Dogma of Molecular Biology support the encrypted output of substitution method using transcription and translation technique.
