Dual Cellular Automata on FPGA: An Image Encryptors Chip

Sundararaman Rajagopalan, Har Narayan Upadhyay, John Bosco Balaguru Rayappan and Rengarajan Amirtharajan

Abstract:
Secure data transmission plays a crucial role in today’s world. While the data in the form of images are required extensively, the need to safeguard the original images has become inevitable. An image encryption based on the architecture of 14-bit and 8-bit cellular automata circuits has been proposed in this study. With the mighty pseudo randomness of two different cellular automata circuits, both shuffling and encryption operations were performed on grayscale images. The algorithm was implemented on Cyclone II EP2C35F672C6 FPGA. The proposed image encryption scheme on the reconfigurable hardware consumed a maximum of 11,675 logic elements (35% of total LEs) and 2,62,144 M4KRAM bits for encrypting the two grayscale secret images of size 128x128 that were stored in internal memory of the FPGA.
