Abstract
Image encryption is not new. Several different encryption algorithms have been used. Some of the algorithms are based on random sequences generated using chao systems and DNA sequencing and others are based on compression. Still, others are based on Linear Feedback Shift Registers. This paper focuses on research solutions for securing digital images including medical images. Medical images are important and are generally regarded as sensitive in nature. In this research paper, higher order linear feedback shift registers are developed using combination of lower order LFSRs by suitable clocking and the ciphers generated are utilized to encrypt digital images. Our analysis involves using suitable metrics to compare the chaos-based and LFSR-based stream ciphers for image encryption. © 2025 Elsevier B.V., All rights reserved.
