Secure and Efficient Image Encryption for UAVs Using 4D Chaotic System

P. Vishnu Vardhan, et al.

Developed as an outcome of the Interdisciplinary Project (IDP 100) at SRM University AP. Designed and evaluated an ultra-fast, robust image cryptosystem tailored for Unmanned Aerial Vehicles (UAVs). Utilizing a custom 4-dimensional hyper-chaotic mathematical map, the system generates high-entropy sequences to encrypt air-to-ground image feeds. Won the prestigious Best Paper Award under the Security and Privacy track.

A Secure Image Encryption Scheme for UAV Applications Using 4D Chaotic Sequences and DNA Encoding

P. Vishnu Vardhan, et al.

Developed a highly robust and lightweight image cryptosystem tailored for secure UAV visual communications. The framework combines high-entropy 4-dimensional chaotic sequences with biological DNA sequence encoding rules, demonstrating exceptional resistance to statistical, differential, and cipher-text attacks. Honored with the Best Paper Award at the ETICT 2K26 National Conference (Sethu Institute of Technology) and currently submitted and under review for international publication.
