Digital image protection is crucial since images often contain private and sensitive information in business, medical, and military. One of the best techniques for securing the content of these images is encryption. This work introduces a cryptosystem known as Elliptic Curve Diffie-Hellman Hill Cipher (ECDHHC) that uses the modified Elliptic Curve Diffie-Hellman (ECDH) key exchange protocol to generate the shared secret key integrated with the Hill Cipher (HC). With this combination, the correlation between adjacent pixels in the ciphered image is effectively removed, and the level of unpredictability and uncertainty for ciphered image is also enhanced. The suggested approach used the key space, entropy, histogram, anti-noise attack, differential attack, and correlation coefficient to evaluate the performance of the encryption method. According to simulation findings, the proposed method offers a high level of security, and efficiency, and resists attackers.
