Multi-Domain Image Encryption using Chaotic Map with DRPE
Rachit Jain, Jaydev Sharma · 2016
In this paper two level image encryption scheme based on chaotic Baker map in DWT domain and DRPE is presented. The original image is decomposed into approximate and detail components using discrete DWT, then the more important one is encrypted using chaotic Baker map followed by inverse DWT. Finally DRPE is applied using two different keys in order to increase security level and to reduce the correlation between pixels. Efficacy of proposed scheme is verified using different performance analysis methods. Simulation results show that correlation, noise immunity and key sensitivity analysis parameters for the proposed scheme are comparable to the other schemes.
