Image Encryption Algorithm based on Elliptic Curves

Abstract

Several cryptography schemes on the images use chaos theory, these schemes are very effective but have weaknesses such as the distribution of keys between the two entities that want to exchange an image confidentially. In this work, we propose an efficient encryption scheme using elliptic curves, we show that the proposed scheme is tamper-proof against any attack. It also proves security because of the problem of discrete logarithm on this elliptic curve whose calculation is difficult. This scheme achieves the required objectives such as non-repudiation, confidentiality, and integrity. During the security analysis of the proposed scheme, we verified that many security attributes have been satisfied.
