DNA Secured Edge Computing for Heterogeneous IoT

Abstract

Edge computing (EC) effectively analyses and stores data near end users and Internet of Things (IoT) devices. IoT is an innovative concept that offers several applications essential to our daily lives. It is crucial to protect data safety because huge amounts of private information are transmitted between these devices. Due to the low computing power of IoT devices, standard cryptography methods are unsuitable. The objective of this paper is to improve a lightweight cipher procdure for heterogeneous smart devices. This paper proposes a three-stage data security (TSDS) algorithm for heterogeneous IoT in edge computing using DNA (Deoxyribonucleic Acid) encoding. DNA encoding is a cryptography technology that uses DNA sequences based on biological functions to encode and decode the original data. The level of security is selected depending on the IoT data confidentiality level. Through tests, the effectiveness of the suggested method is evaluated in terms of encryption and decryption times. The proposed algorithm uses simple, lightweight encoding methods with DNA operations. The suggested technique efficiently hides the data from unauthorized access with the help of DNA. It reduces encryption and decryption time. It is more reliable and lighter, which makes it appropriate for low-power IoT devices.
