Two-Fold Cryptography: Enhancing Image Security with Henon Map

Abstract

This paper presents a robust approach to image encryption by employing the Henon map in a dual-layered cryptographic framework. The method, termed 'Two-Fold Cryptography,' enhances image security by subjecting them to dual encryption processes. The key parameters derived from the Henon map dynamically influence both encryption stages, contributing to intricate and resilient security architecture. Results demonstrate that the Two-Fold Cryptography approach significantly bolsters image security, surpassing traditional single-layer encryption methods.
