Secure image encryption and authentication using Gaussian elliptic curve and complex invertible matrix

Image transmission in security-critical applications requires strong confidentiality, integrity, and key management. This paper proposes a Chaotic Complex Elliptic Curve-based Secure Image Encryption (CCEC-SIE) scheme operating in the Gaussian domain. By extending elliptic curve cryptography to Gaussian integers, the p...
