An efficient environmental monitoring data encryption algorithm based on DNA coding and hyperchaotic system

Securing data in wireless environmental monitoring systems based jointly on Deoxyribonucleic Acid (DNA) database and chaotic sequences is a hot new research topic. This paper deals with the implementation of an encryption scheme combining DNA cryptography and the pseudorandom property of hyperchaotic behavior to secure data from air quality monitoring stations. We propose an appropriate cryptography algorithm, which guarantees the confidentiality, integrity, and authentication of data. The dynamics of the hyperchaotic system was studied in order to be able to make a wise choice of the sequence to be used in the encryption and decryption processes, which will be used at all stages of the cryptosystem to strengthen data security. Several studies including security analysis, execution times as well as a comparative study with some existing algorithms were carried out to assess the resistance to attacks of the proposed scheme. The performance analysis demonstrated the ability of the proposed cryptosystem to resist various attacks through a low execution time and a large key space.
