A Novel String Matrix Data Structure for DNA Encoding Algorithm

摘要

DNA Cryptography is a rapidly emerging field of DNA Computing research to provide invincible cryptographic technique for the modern cyber world of today and the futuristic DNA computers. Several DNA based cryptographic algorithms are proposed for encryption, decryption and authentication, etc. The first and foremost step of DNA based encryption is DNA encoding of plaintext. The main limitation of DNA encoding is the absence of effective, randomized, dynamic, secure DNA Encoding technique for DNA encoding of plaintext. To overcome this limitation, this paper describes a novel DNA encoding algorithm. This encoding algorithm is based on a novel string matrix data structure, for generating the unique DNA sequences that can be used to encode plain text (comprising of alphabets, numbers and special characters) as DNA sequences. The experimental results and comparison results have proved that the proposed DNA encoding algorithm is more effective than the existing DNA encoding algorithms.
