DNA-Based Cryptographic Method for the Internet of Things

Abstract

Internet of Things (IoT) is a set of connected smart devices providing and sharing rich data in real-time without involving a human being. However, IoT is a security nightmare because like in the early computer systems, security issues are not considered in the design step. Thereby, each IoT system could be susceptible to malicious users and uses. To avoid these types of situations, many approaches and techniques are proposed by both academic and industrial researches.DNA computing is an emerging and relatively new field dealing with data encryption using a DNA computing concepts. This technique allows rapid and secure data transfer between connected objects with low power consumption. In this paper, authors propose a symmetric cryptography method based on DNA. This method consists in cutting the message to encrypt/decrypt in blocks of characters and use a symmetric key extracted from a chromosome for encryption and decryption. Implemented on the embedded platform of a Raspberry Pi, the proposed method shows good performances in terms of robustness, complexity and attack resistance.

Nested Levels of Hybrid Cryptographical Technique for Secure Information Exchange

“…The results of the experiment show that, when measured in terms of cipher text size, encryption time, and throughput, suggested technique performs better than standard algorithms. Khobzaoui et al [12] have implemented DNA cryptography with help of chromosome and it was symmetric type of cryptography. The technique involves encrypting and decrypting the data in blocks of characters while using a symmetric key that was retrieved from a chromosome.…”

DNA sequences for robust encryption: a strategy for IoT security enhancement

“…Benyahia et al [5] propose a symmetric cryptography system based on DNA called Stegano-DNA-which operates under two main modules: scrambling and encryption .In [22] , the authors propose a symmetric crypto-system which consists in cutting the message to encrypt/decrypt in blocks of characters and use a symmetric key extracted from a chromosome for encryption and decryption. In studies [17], Khobzaoui et al presented a symmetric cryptosystem that involves segmenting the message to be encrypted/decrypted into character blocks and using a symmetric key derived from a chromosome for both encryption and decryption processes. Abdelkader et al [1] presented a novel two-level encryption/decryption scheme that merges the principles of cryptography and steganography is proposed.…”
