The content security of digital images is a hot topic in both academics and business because to the growing usage of media in communications. In the meanwhile, users of symmetric cryptosystems must manage and transmit keys. This study suggests an elliptic curve-based asymmetric image encryption technique (ECC). The Diffie-Hellman public key sharing method is used to determine an elliptic curve point that is agreed upon by both the sender and the recipient. The sender first puts pixel data together and turns them into large numbers to shorten the encryption timings. Second, the sender uses the chaotic system and ECC to encrypt large integers. Finally, huge integers that have been encrypted are used to create the encrypted image. The suggested technique makes key management and transmission comparatively easy and secure. The suggested algorithm displays excellent security and great efficiency, according to simulation data.
