Abstract

Recently, several image encryption schemes based on chaotic maps have been proposed. Most of them hinder the system performance, security, and suffer from the small key space problem. This paper presents a image encryption using modified 4 out of 8 code and chaotic map. Generally image encryption involves permutation and substitution network. Here permutation is done by using chaotic map and using modified 4 out of 8 code carrier image is generated with the help of alpha-numeric keywords and also special characters. Substitution done by performing XOR operation between permuted image and carrier image to get a encrypted image. Simulations have been carried out and the results demonstrate the superior security and high efficiency of the proposed scheme.
