ABSTRACT
Nowadays smart phones and wireless data communication are serving as the key components in any communication system of digital world. Furthermore, data being shared in the course of this medium is quite sensitive during both transmission and reception phase. Hence, it is greatly recommended to protect the shared data from frauds and spam. Furthermore in today's smart world of Internet of Things (IoT), a variety of objects are connected through the same wireless network like smart home appliances, personal smart phones, other gadgets related to work from home or school from home in these tough COVID-19 situations. One of the best wireless networks equipped with secured and efficient channel is needed to work upon. In this paper, author has proposed a Novel Improvised Advanced Encryption Standard (NIAES) for secured image or video sharing over wireless network. Here, a novel way of construction of Substitution Box (S-Box) is proposed with the extensive formulation of an improvised version of the equation while dealing with the square matrix construction throughout the affine transformation stage of proposed NIAES scheme. The proposed NIAES was found to be speedy, more secured and efficient based on various performance and quality parameters. Copyright © 2022, Anka Publishers. All rights reserved.
