TL;DR

This paper proposes a novel bi-serial DNA encryption algorithm (BDEA) that leverages DNA digital coding, number conversion, and PCR amplification to transform plaintext into highly secure ciphertext. By integrating biological principles with cryptographic techniques, BDEA achieves strong resistance against cryptanalysis, demonstrating enhanced security through hybrid DNA-biochemical operations.

ABSTRACT

The vast parallelism, exceptional energy efficiency and extraordinary information inherent in DNA molecules are being explored for computing, data storage and cryptography. DNA cryptography is a emerging field of cryptography. In this paper a novel encryption algorithm is devised based on number conversion, DNA digital coding, PCR amplification, which can effectively prevent attack. Data treatment is used to transform the plain text into cipher text which provides excellent security

Motivation & Objective

• To develop a new encryption method that leverages the inherent properties of DNA molecules for enhanced data security.
• To address vulnerabilities in traditional encryption by integrating biological computation principles such as DNA coding and PCR amplification.
• To improve resistance against cryptanalytic attacks through the use of bi-serial transformation and parallel processing in DNA-based operations.
• To explore the feasibility of combining number theory with molecular biology for advanced cryptographic applications.
• To provide a secure, energy-efficient, and scalable encryption framework using DNA's high information density and parallelism.

Proposed method

• The algorithm begins with number conversion of plaintext data into DNA sequences using a predefined DNA digital coding scheme.
• It applies a bi-serial transformation process that manipulates DNA sequences in two parallel serial streams to increase complexity.
• PCR amplification is used to replicate and enhance the encoded DNA sequences, increasing redundancy and security.
• The method integrates principles from number theory to ensure unique and non-repeating transformations during encoding.
• The final cipher text is generated by converting the processed DNA sequences back into digital form using reverse coding rules.
• The entire process is designed to exploit the vast parallelism and high information density of DNA molecules for robust encryption.
