Cybernetics and Information Technologies, 23(3), 126-144. https://doi.org/10.2478/cait-2023-002913119702https://doi.org/10.2478/cait-2023-0029https://hdl.handle.net/20.500.12519/960In this work, we build upon an implementation of a peer-to-peer image encryption algorithm: "Rubik's cube algorithm". The algorithm utilizes pixel-level scrambling and XOR-based diffusion, facilitated through the symmetric key. Empirical analysis has proven this algorithm to have the advantage of large key space, high-level security, high obscurity level, and high speed, aiding in secure image transmission over insecure channels. However, the base approach has drawbacks of key generation being handled client-side (at nodes) and the process is time-consuming due to dynamically generating keys. Our work solves these issues by introducing a Key Distribution Center (KDC) to distribute symmetric keys for transmission, increasing confidentiality, and reducing key-generation overhead on nodes. Three approaches utilizing the KDC are presented, communicating the dimensions with KDC to generate keys, standardizing any image to fixed dimensions to standardize key-generation, and lastly, using a single session key which is cyclically iterated over, emulating different dimensions. © 2023 Aswani Kumar Cherukuri et al., published by Sciendo.This work is licensed under the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License.ArticleCopyright : © 2023 Aswani Kumar Cherukuri et al., published by Sciendo.
