In the past few years, the transmission of digital images across the world has increased. Images such as military images, personal photos are transmitted which are not intended for all. It is essential to secure these images from unauthorized access and modifications. Chaos theory is a scientific discipline that deals with non-linear dynamical systems that are effectively impossible to predict or control. Lorenz attractor is one such chaotic dissipative flow used for image encryption through the generation of confusion matrix. In the encryption method used, image is considered as a cube. To generate the confusion matrix, Lorenz attractor is applied on every coordinate of the cube [1]. We have proposed a fast encryption scheme called FIELA, in which novel improvements to the bin creation and sorting scheme have been implemented to harness the power of parallel computing resources like GPUs and multi-cores.
