Abstract

A new symmetric cryptosystem is proposed in this paper which will be used to carry out image encryption without compression. The proposed system has been developed to encrypt images in BMP format. A significant contribution of this investigation is the use of one solution point of a zero valued constant elliptic curve in order to generate a set of 15 encryption keys. On the other hand, using a differential equation that produce chaotic numbers a permutation and its inverse permutation are generated. Every encryption key and both permutations are the same size as the image. The proposed cryptosystem is tested for the purpose of verifying its resistance against several cryptographic attacks as well as the randomness and quality of its ciphering. Results are showed and compared with some recent scientific articles published between 2017 and 2019.
