Increasing robustness of data encryption standard by integrating DNA cryptography

Abstract

Encryption has become a necessity of life, especially in the field of exchanging and transmitting data through transmission media, such as internet, wireless networks, mobile networks, bluetooth, and infrared. The deoxyribonucleic acid (DNA) cryptography is a very promising approach which is shown to be efficient in computation, storage, and transmission. In this paper, we introduce a new technique for encryption called DNA-DES that is more robust than traditional data encryption standard (DES). The proposed technique integrates concepts derived from DNA, ribonucleic acid, and nucleic acids to increase the key space and number of available permutations of traditional DES. The theoretical and experimental analysis show that the proposed DNA-DES method is efficient in computation, storage, and transmission. The security analysis proves that DNA-DES has high confidential strength against brute-force and cryptanalysis attacks.
