Cryptography method based on hill’s cipher And ECC in image processing

hill’s cipher is a symmetric cryptography algorithm which is based on blocking cipher and use array computation to encrypt a message. in this article we want introduce new application of hill’s cipher cryptography in digital image processing to encrypt an image and ECC totransfer the key during an unsecure channel to decrypt it. The method involves each type of images including binary, gray scale and RGB images.
