End-to-End Security Scheme for E-Health Systems Using DNA-Based ECC

Today, the amount of data produced and stored in computing Internet of Things (IoT) devices is growing. Massive volumes of sensitive information are exchanged between these devices making it critical to ensure the security of these data. Cryptography is a widely used method for ensuring data security. Many lightweight cryptographic algorithms have been developed to address the limitations of resources on the IoT devices. Such devices have limited processing capabilities in terms of memory, processing power, storage, etc. The primary goal of exploiting cryptographic technique is to send data from the sender to the receiver in the most secure way to prevent eavesdropping of the content of the original data. In this paper, we propose an end-to-end security scheme for IoT system. The proposed scheme consists of (i) a secure and efficient mutual authentication scheme based on the Elliptic Curve Cryptography (ECC) and the Quark lightweight hash design, and (ii) a secure end-to-end communication based on Deoxyribonucleic Acid (DNA) and ECC. DNA Cryptography is the cryptographic technique to encrypt and decrypt the original data using DNA sequences based on its biological processes. It is a novel technique to hide data from unauthorized access with the help of DNA. The security analysis of the proposed scheme reveals that it is secure against the relevant threat models and provides a higher security level than the existing related work in the literature.
