A New Lightweight Encryption Approach for Correlated Content Exchange in Internet of Things

So far, many cryptography systems adapted to Internet of Things (IoT) paradigm have been introduced. However, in these approaches, the constraint of images exchange has not been taken into consideration. In fact, image content is characterized by the correlation between its elements e.g. pixels. Correlation impacts negatively the security. Actually, using correlation, one can disclose data content once he/she has recognized a part of it. In this paper, we introduce a new cryptography system that takes into consideration correlation issue. Furthermore, our system allows reducing significantly memory use and time consumption, which are critical factor in IoT dedicated cryptosystems.
