A Lightweight Encryption Algorithm for Edge Networks in Software-Defined Industrial Internet of Things

With the development the industrial Internet of Things, a series of problems and challenges have emerged, and in order to solve these problems, many scholars and researchers have introduced software-defined networks into the Industrial Internet of Things. The introduction of software defined networks solves some of the problems, but there are still many problems to be solved. In this paper, we mainly analyze the safe transmission of data in the software-defined industrial IoT edge network. First, we analyze the special requirements of the data in the software-defined industrial IoT edge network. Then we analyze the principles and characteristics of several known lightweight encryption algorithms, and point out why the currently known lightweight algorithms cannot be directly used in software-defined industrial IoT edge networks, and we propose a new lightweight encryption algorithm. Finally, in this paper, experiments and evaluations of new lightweight encryption algorithms are carried out in several aspects. It is known from experiments that the lightweight encryption algorithm proposed in this paper satisfies the special requirements of software-defined industrial IoT edge network for data transmission.
