An image encryption using chaotic permutation and diffusion

A lightweight and efficient digital image encryption using hybrid chaotic systems for wireless network applications

“…To evaluate the performance of our proposed image encryption scheme and check its security efficiency, we conduct several simulation experiments using the Matlab platform. We use Matlab R2012b under Windows 8 professional on We use in the simulation different standard test images from CMU and USC-SIPI databases in order to compare our results with other recently proposed algorithms [26,27,30,[37][38][39].…”

“…This study proposes a lightweight and efficient digital image security scheme based on chaotic theory for wireless networks. Our proposed scheme encrypts efficiently the images and resists against most attack types, and adds mini- 15.2563 Yashasvee et al [24] 130.6902 Gopalakrishnan et al [27] 0.2428 mal impact on node computational overhead and overall network communication performance. The proposed scheme is implemented in two phases: image compression, and image encryption.…”

“…A chaos-based image encryption scheme is proposed by Gopalakrishnan et al [27] with permutation and diffusion structure. The proposed encryption scheme undergoes three phases: mixing process, permutation process, and diffusion process.…”

“…Finally, the encrypted image is further confused by pixel shuffling and displacement algorithm. In the work of [27][28][29], we notice that the encryption process is also done in pixel-wise manner which requires extra calculations and processing time.…”
