Abstract
En 中文
In this paper, an image encryption technique is proposed to encrypt the images by using a 2D Logistic map with the SHA-256 sequence generator. The initial conditions and control parameters of the chaotic maps served as the key for the cryptosystem, and were made dependent on the plain image through the SHA-256 protocol. The internal loop of the proposed image encryption method is made of 2D logistic permutation, and 2D logistic diffusion. In order the proposed system performance, widely known and accepted metrics as keyspace, key sensitivity, histogram, correlation and entropy were computed. Experimental results showed that the proposed approach was highly key sensitive and exhibited a good resistance against brute-force and statistical attacks. The cryptosystem presented in this part was designed to ensure the safe exchange of medical images on the 5G telecommunication network using IoHT in the interconnexion of different hospital services.
