RARE: A robust algorithm for rapid encryption

摘要

Regarding the intensive use of images in the context of IoT, their security becomes crucial. Despite that severals lightweight ciphers have been proposed, they are not suitable for images data due to their features such as correlation, redundancy and voluminosity. In this context, we treat in this paper the weaknesses of the existent lightweight ciphers concerning the constraints of images. Additionally, we propose an appropriate lightweight image cryptosystem that takes all the features of this kind of data. The experimental results show the effectiveness of the new scheme compared to existent ones.
