Abstract
The internet has become an integral part of our modern life, and the protection of secret data over the internet of multimedia things is the fundamental concern for Smart City applications. Nowadays, the widely used internet of things (IoT) uses audio, image, video, and various mixed modes as well, where privacy, as well as security, are equally essential in real-time transmission. Substantial research has been reported on various encryption algorithms for text and image files, but a similar need for video encryption has been felt a little late. It may be noted that the absence of any standard encryption technique designed especially for any video file has compelled us to design a new but quite robust encryption algorithm for video input as secret. This article has primarily addressed the security needs for video content in IoT. Any video file can be considered as a collection of continuous images. In this research article, we have dealt with video encryption, fundamentally a multi-round key-based shuffling of a collection of images, components of the original video file to be encrypted. The proposed novel scheme follows the fundamental concept of the symmetric encryption technique, where the encryption key is common for both encryption and decryption in real-time video applications.
