Abstract:

The advancement of technology has sped up the process of data transfer in the expansion of multimedia and communication tools. Digital images are one of the most frequently used data types in data transfers. These images may contain personal and confidential information. When images are sent over a public network, it is crucial for information security to transmit them to the receiving party in encryped format. Chaos-based methods are the most commonly used image encryption techniques. In this study, a confusion and diffusion based image encryption method is designed and implemented in real time on Jetson Tx2 and Jetson Nano embedded systems using Henon and Tent chaotic maps. To evaluate the performance of the implemented image encryption system, the most frequently used images in the literature are subjected to security tests such as histogram analysis, correlation analysis, and key sensitivity analysis. Moreover, the proposed system is evaluated by comparing the encryption and decryption times of two different embedded systems. The results clearly demonstrate that proposed image encryption system has a highly secure.
