Image encryption based on the finite field cosine transform

作者：

Highlights：

• A novel image encryption scheme is proposed.

• The technique involves two steps, where the finite field cosine transform is applied to blocks of an image.

• The proposed scheme provides benefits related to computational complexity and encoding of the ciphered-images.
