with the increasing use of media in communications, the content security of digital images attracts attention from both academia and industry. In This paper proposes an asymmetric image encryption algorithm based on a Homomorphic cryptosystem (Paillier) with an elliptic curve. The algorithm is used for securing images that are transmitted over a public unsecured channel. The Homomorphic property with an elliptic curve is used in this paper, the proposed approach consists of three stages: key generation, encryption, and decryption. To realize such an approach, the encryption cryptosystem must support additional operations over encrypted data. This cryptosystem can be effective in protecting images and supporting the construction of programs that can process encrypted input and produce encrypted output while preserving the original execution time of the proposed algorithm.
