Design and analysis of a secure image encryption algorithm using proposed non-linear RN chaotic system and ECC/HKDF key derivation with authentication support

Abstract Ensuring digital image security is critical in today’s edge computing and networked communication environments. Chaotic systems offer powerful tools for lightweight, real-time encryption, but often suffer from limited chaotic ranges and weak key sensitivity. This paper introduces a robust n...
