A secure cryptosystem using DNA cryptography and DNA steganography for the cloud-based IoT infrastructure

Abstract

In this digital era, most of the data of an Internet of Things (IoT) infrastructure are communicated over the internet and they are stored in a cloud environment. As there are numerous users and attackers over the internet, IoT data face many security issues. Currently, Deoxyribonucleic Acid (DNA) cryptography is a cutting-edge area, which is used to enhance data security. In this paper, a novel cryptosystem is proposed using DNA cryptography and DNA steganography for the cloud-based IoT infrastructure. Here, the confidential data is encrypted by using a long secret key. Then, it is hidden in an image. Thus, the proposed cryptosystem not only hides the data, but also encrypts the confidential data prior to storing it on the cloud server, and it resists many security attacks in the cloud-based IoT infrastructure. To evaluate the performance of the proposed scheme, many experiments are performed. The results show the effectiveness of the proposed scheme.
